Electric Bikes: Gateway Drug to Bike Commuting?

st1_b_m_e_c_ckeWhat would the world be like if almost anybody could ride a bike effortlessly, at any speed they choose, regardless of physical fitness, hills, headwinds, or drag from the bike trailer full of kids and groceries?  What if even those of us who are not athletes could get all the glorious benefits of cycling including invincible health, complete freedom from traffic jams, free Rockstar Parking everywhere, and Zero Dollar Gasoline, forever?

This is the promise of the Electric Bicycle, a trend that has become enormous in Asia and Europe and is finally making its way here to North America.

Temporary Note – the EbikeKit company has a sale running until October 21st. Jason has decided to allow combining the coupon code “MMM” created for this article on top of this sale to get a total of 21% off their kits

The basic idea is that you take a regular bike but swap out one of the wheels for a different one with an electric motor built into the hub. Add a battery, basic control electronics, and a motorcycle-style twist throttle, and you have created an astonishing Frankenbike that allows you to perform like Lance Armstrong at Maximum Sprint, without even breaking a sweat. Depending on the model and style, Ebikes can attain top speeds anywhere between 15 and 50 MPH, with ranges from 10-50 miles.

To put the value proposition into the simplest form possible, this is why I am excited about this invention:

Convenient range for various cyclists

Convenient range for various cyclists

This table is obviously just an approximation. Steep hills or humid summers may reduce a beginner cyclist’s range even further, and meanwhile some readers can crank out 15 miles before the first bead of sweat forms upon their brow. But the bottom line is that these things get you further and faster, with the option of little or no sweat.

At this point I need to admit that I’m personally not the ideal electric bike customer. I live in a town that is 5 x 5 miles and I rarely leave here except to go to the airport. Standard leg-powered bikes have been getting me around this place easily for 9 years and they allow me to carry everything from groceries and kids right up to major appliances. With my 40th birthday coming up next month, I don’t need to be getting any less exercise. And while we do also have a car and a minivan, both are still sipping on the tanks of gas I bought them in April 2014.

But hey, I like speed at least as much as the next guy, and I’ve been known to own a fast motorcycle or two in earlier years and also perilously approach highway speeds on a snowboard. On top of that, electric propulsion is absolutely the future of personal transport – chant out the usual oil exec slogans all you like, but electric cars are already here and they make their gas counterparts look like tragic clown dinosaurs by comparison. I’ve been researching electric vehicles for years now, and looking forward to the day when we can all make the switch.

I test drove a 2015 Nissan Leaf over the summer and was floored by its lightning acceleration, solid handling, silky silence even at 90 MPH, and general 5-door practicality. If we could take the benefits of that, and scale them down to bicycle size so we could still get some fresh air and exercise (and spend a lot less than the price of a new car), it would be even better.

So I built myself an electric bike recently, with the goal of evaluating long-term performance and reporting it back to you. It is a hell of a lot of fun, and I’ve been blasting around town (and country) on it for several days now. But before we get into the details of my setup, let’s take a look at the whole ebike scene to see where everything fits in.

In my mind, it breaks down to three categories, which will appeal to different people:

Off-the-Shelf Electric Bikes ($600 – $10,000)

The Stromer Sport (image credit nycewheels.com)

The Stromer Sport, with battery compartment shown open (image credit nycewheels.com)

These are the easiest (but generally most expensive) option. Last year, I toured the inventory at Small Planet E-vehicles here in my own town, and test rode some very fancy bikes. My favorite was the $2800 Stromer Sport, which senses your pedaling effort and adds the proportional boost of your choosing, which feels exactly like being a bionically enhanced superhero. However, the bionic boost gets you no faster than about 25MPH, as the pre-made bikes must comply with federal e-bike speed limits.

Pros: Ready to go immediately. Sit on it and start riding. Just plug it in every now and then to recharge. This is the option for people with more money than mechanical skill, and a desire to get out into the fresh air immediately.

Cons: More expensive, top speed (while still swift) will not appease speed demons like myself.

Examples: Stromer, Prodeco, and Pedego are some of the leaders in this field. Some car manufacturers are offering their own take on E-bikes including the SMART (owned by Mercedes), BMW, Audi (prototype only), and KIA.

 Complete Conversion Kits ($800-$2000)

Here's the kit I used, from ebikekit.com

Here’s the kit I used, from ebikekit.com

Several companies are now putting together kits that allow you to take almost any existing bike and convert it to electric drive. The motor, battery, controller, and any accessories are all designed to work together with matching plugs, voltages, etc.

This is the option I chose for myself, because I wanted to profile something within the technical skill of the average bike owner. If  you can change the back tire on a bike and install a bike speedometer, you can install this kit. On top of that, I was able to get advice from Ebikekit* founder Jason Kraft about exactly what setup would best fit my existing bike and align with the way I use it.

I ended up with a 500 watt direct drive motorized rear wheel, a 13 amp-hour lithium battery, plus everything required to use it and charge it at home. The total list price of my setup with shipping was about $1600, although with strategic use of discounts, this can be had for about $300 less. We’ll get into how well this system works at the end of the article.

Pros: Top e-bike quality at lower cost. Unrestricted speed. Flexibility in choosing your own bike and exactly how you want things installed. Easy to upgrade battery later.

Cons: A bit of work to install (mine took 1 hour). A slightly more homemade look to your bike.

Honorable Mention: Although it is not yet available for general delivery (release date seems to bump out another three months every time it gets close), the Copenhagen Wheel is a $700 conversion that has everything – battery, motor, and control electronics – packed seamlessly inside the wheel itself. It senses and boosts your pedaling effort and links with your smartphone to present an incredibly fancy yet simple user interface. Because of the splendid ease of use, this will probably change the face of electric cycling forever. But it’s still not as fast as the full kit above.

Fully Customized Systems for Hackers:

reader kit

This is the full setup of a monsterbike built by an MMM reader who helped me when researching this article.

Just as it works with home renovation, auto maintenance and most other practical fields, if you bring more knowledge and effort to the table, you can build a system to your own specifications and potentially save quite a few dollars in the process.

For example, if you search Ebay for “electric bike kit“, you’ll find basic straight-from-China front wheel kits for about $260, then you’d add a 48V Lithium Ion battery for about $400 – $600 with shipping, depending on capacity. The downside is the risk of part failure (and I wouldn’t expect the greatest support if anything breaks), and the need to splice and solder a few wires here and there to get everything to work together.

Or instead of cheap, you could go for high-end. At the forum called Endless Sphere, enthusiasts spend hours doing detailed reviews and extensive discussion. One MMM reader sent me a full description of the $3400 ebike he built from the ground up that easily does 35MPH and regularly rocks a 42 mile roundtrip commute in a hilly area with high winds.

A Quick Primer on Terminology:

If you are going to look into one of these yourself, here are the basic things to know:

The Motor: 250 watts, 500 watts, or more?

Think of it this way: a fit cyclist can put out about 150 watts for an extended period of time. If you combine this with a fairly streamlined bike, you’ll end up zooming along at about 20MPH. During a quick sprint of acceleration, the same cyclist can put out over 745 watts (1 horsepower) for short periods of time. So even a 250 watt motor can beat you in a long race, and 500 watts is almost like sprinting at full speed. Sure enough, my 500 watt motor tops out at just over 30MPH if you are letting it do all the work, which is about the fastest I can pedal a conventional bike for short sprints without assistance. When I set my own legs and the motor to maximum output, we can achieve over 35MPH together.

Voltage: 36 or 48 volts? This doesn’t strictly matter, although you will generally find 48 volt batteries and motors in the higher-powered systems.

Lithium or Lead Acid Batteries? In my opinion, Lithium batteries are the only way to go. The older technology Lead-acid batteries are heavy and bulky, which are both properties you want to minimize in a bike. On a trike or golf cart, however, Lead batteries are fine.

What are Amp Hours and How Many Do I need? To understand battery capacity, multiply the “Amp hours” by the “Volts”.  My new system is 13Ah x 48 volts, which gives us 624 watt hours (also known as 0.624 Kilowatt Hours, to put things in the context of my old Electricity article.) To put this simply, the battery holds energy equal to about four hours of intense cycling. The neat part is that charging it only requires about seven cents of electricity, which is way less than the cost of the enormous meal I devour after returning from a 4 hour ride!

So what is the range of these things?

Just as with a car, that depends on how fast you drive it. On a recent outing to the far side of Boulder (a 30 mile roundtrip), I rode my own bike at a swift 28-30MPH speed the entire time, pedaling along at my own normal energy level. This used up about 75% of my battery pack, which means the total range with this fairly intense use is about 40 miles. Just like an electric or hybrid car, you get better mileage in the city than on the highway, and my trip was mostly highway.

So tell me about the Mr. Money Mustache E-bike!

This post has grown quite long, so we’ll save the detailed analysis and testing for my second article in this series, which will come after I get some more miles on the clock . I’ve also recruited a friend to build one of those Customized Hacker Systems in order to compare his results with my own with the premade kit.

Here’s what my bike looks like so far. It is a fairly incognito setup, and the battery bag is simply held on with bungee cords at the moment. But so far, so good. The added speed of this thing has expanded my options for speedy errands around town, and it just might prove to be a revolution even for me. Tune in next time to learn more.

mmm_ebike

Here’s my regular city bike, now enhanced with Electricity. 100 miles into the test, it is already lots of fun, but more development is still in the works.

    I’m looking forward to article 2, I hope with care taken to analyze how it affects your effort and how it performs when hauling. I’ve done a lot of research on e-bikes with the hope that a conversion of my surly LHT would turn me from an 18mph stud into a 36mph road monster. I’ve never executed the plans because of the fear that instead of a road monster I become a lazy git.

      I wonder if you could create a “battery backpack” and plug it up when you get on the bike. If they didn’t get too hot, you really could get that extra boost of power that you’ve been looking for :-)

    I just bought an ebike from Amazon just about a week ago. I haven’t received it yet (should be here Friday), but I have read many great things. Mine was $550 (including shipping) and had some great reviews, just the usual complaints. I cannot wait to get it and start riding instead of walking! It will definitely prevent those times when I want to be lazy and take the car! Anyone who wants to know more, just look for Watseka bikes. It is a lead-acid battery, but for the price, it can’t be beat (at least that’s my opinion). Thank you, MMM, for another great article. I always look forward to your posts.

      Trevis, You’ll love your electric bike but one thing you’ll give up when you go with a bike that cheap is the battery. The higher priced bikes have lithium batteries. Lithium batteries have 1000+ charge cycles so they will last years instead of 200-300 charge cycles on the lower end batteries. The cheaper bikes also have less range, lower speeds, and less power. The good thing is that after a year you can replace the battery, sell it, and upgrade to a better bike, with a better battery and motor.

      • Trevis Kelley October 7, 2014, 3:39 pm

        I received the bike and have tried it out for a couple of days. It needs a good charge when it gets here and the battery indicator is not the most accurate. I took it out for a spin without the motor, and it definitely requires some good leg power due to it’s heavier battery. Not a bad bike, though. Comes with a head and tailight for night riding, a horn, and a front basket. Good stuff. It is definitely not a high-end bike, but for someone just getting back into biking, it’s a good start. It has enough power to move this 280 lb guy around, so it should handle most people here. Only real complaint I have so far is the seat is hard as a rock. It hurts pretty good after even a minute of riding. Range is also somewhat shorter than what I would expect the higher-end ones to have, but is less than a third of the price.

        Mini,
        I am sure that you found the one. Maybe mine was on a sale, though it wasn’t listed that way. I don’t think Watseka makes another bike (yet). I guess I got lucky getting it when I did. $650 still isn’t bad in the world of ebikes.

        Matt,
        Yeah, I know I am. I am saving close to $2000/yr by switching my phones to Republic – guess where that first year’s savings are going! I am considering using the frame of this bike and getting a FlyKly, which would save me a bunch of money. It would also allow me to start customizing the seat and other things right away. I don’t know what makes a great frame, so I am still researching. I am definitely open to any and all advice out there!

        Just wanted to let everyone know that the bike does work and, while I wouldn’t call it amazing, it is a very solid ebike for such a low price. I recommend you at least keep it in mind when you are shopping.

          Trevis, fear not regarding the hard seat! All new cyclists think that the saddles suck but it is just a matter getting used to riding a bike. They key is to start with short trips and do them regularly. A little bit of voluntary discomfort and badassity is involved, but will help prevent buying extra saddles you don’t really need. Sheldon Brown is a top resource on bicycle info and has a more elaborate article on this subject:
          http://sheldonbrown.com/saddles.html

          That said, some saddles are truly shitty but this is very uncommon. Give it some time.

    I clicked on the snowboard link, and almost and was about to call absolute BS on the speed…But I realized it was 93.9 km/h not mph, lol. 93 mph would be extraordinary. Still 93.9 km/h / 58.3 mph is real fast on a snowboard and beats my top speed ever, well done!

      I don’t ride in the highway traffic lane, silly – the bike lane or shoulder is where you go when you’re below traffic speed. The “highway” in this case is just the Diagonal / 119 road between Longmont and Boulder. Speed limit is 50-65, so it still functions as a highway for cars.

For now, Mr. Frugalwoods conducts his daily commute on a regular ol’ leg-powered bike and I scrabble along on my Girls’ Huffy bike (in magenta & teal no less). I really should get a proper adult bike, but, you go to town with the bike you have. Or at least I do for now.

    Oh good, something I can contribute to.

    First of all, never buy a commercial e-bike. Aside from the expense, there are essentially no standards so every company has their own proprietary crappy components. Also the market hasn’t shaken out yet so half of the companies might not even exist anymore if something breaks two years down the line.

    My brother has been into electric bikes for years and has this one: http://clevercycles.com/blog/2012/10/30/xtracycle-reinvents-its-own-with-edgerunner-and-some-backstory/
    Rides everywhere with his two kids in the back and put 10,000km on it in the first year of ownership.

    My wife has a ~13km commute to work. When she went back to work after mat leave I converted her bike to electric to give her the push to switch from the bus to biking to work. She started with the electric but in the summer she removed the battery and just rides it as a normal bike to get the extra exercise. Great success at making the transition to biking.

    I ride a normal bike to work and take our daughter in the bike trailer, but to replace my motorcycle I built a powered BOB trailer for hauling gear. So huge reduction in costs by getting ride of the motorbike and it’s awesome fun to burn around with the trailer pushing you, you don’t have to modify your bike at all, and I can load on $100 of groceries and still power up the steepest hill at 25km/h. I found for errands that I used to drive to I now take the bike with power trailer and get there just as fast or faster, so my riding increased.

      This– what you said about your wife needing a ‘boost’ to get started. Three years ago, when I started trying diligently to ride to work, it was really hard to get my butt in gear, up a couple of big hills, etc. Now I wouldn’t want an e-bike– the main reason I bicycle is to get in a little bit of cardio thumping before and after work– without the exercise benefit it’s not worth the anxiety of being in traffic to me.

      That BOB trailer idea is fantastic. The Mustachian community is really bringing it today!

      I’m curious how you handle breaking with the powered BOB trailer pushing you. Is there something wired to your handlebars which lets you kill the motor?

      • Leo October 1, 2014, 8:28 pm

        I have a twist throttle on the handlebar so I have full control. When it’s set to cruise control technically I should have a brake cutoff switch to make the whole thing legal but it works without.

      I have to disagree with the “never buy a commercial e-bike” sentiment. While there are certainly some dodgy e-bike manufacturers out there, there are also plenty of established players in the market. I own a Stromer ST1 Elite and the Stromer brand is a subsidiary of BMC…not exactly a lightweight in the bicycle field. I’m willing to bet they’ll be around in the years to come. While there are many proprietary components on the bike (namely the controller and battery tech), pretty much everything else is quality off the shelf, including the motor which is found on several other competing e-bike brands. So I think I’d rephrase it to “don’t buy a complete bike unless it’s from a reputable company” and I’m with you 100%.

      I certainly thought about the build it yourself route, but the reviews of the Stromer were just so good and the complete package is so well put together that I couldn’t argue, even with the high price. Since buying it my 1:50 minute round-trip commute by bus dropped to 50 minutes total and just in terms of time regained it’s already paid for itself twice over in a little more than a year of ownership!

        I have the Stromer ST1 Platinum (no speed limit but pretty much tops at 30) that I commute 16 miles each way to work because housing prices near work are nearly double (and I can’t justify that). It is an amazing bike. It has good speed, I really like how the battery is hidden in the tube, it feels like a normal bike in every way except it’s heavier (about 60 pounds), but small price to pay for how fun it is and how fast I can get to work.

        I usually get home about the same time it took to drive (sometimes faster) without having to be frustrated I am wasting time on the parking lot er… freeway. You still get a good workout but it makes going up hills much faster and easier plus maintaining top speed on flat areas is a lot easier. It will still pay for itself over time vs car commuting and I bike a lot more now than before when I had a regular bike. It also increases your confidence because you feel like you can ride anywhere as long as the battery doesn’t die, but for the Stromer it has so many gears that if it did die, it’s not a huge deal, you can still make it home, but I have only had that happen once on a 50 mile leisure ride.

        Negotiate with the bike shop you can get significant discounts. Mine was about 3k for the top model which was well worth it to me as it made the 32 miles a day not so “scary” and is actually really fun.

        I do get a few “damn ebikes” in jest as I pass normal bikes up the big hills which is pretty fun and have noticed a large uptick in ebikes around here.

        Highly recommend it especially if you are not too excited to ditch the car yet and commute to work, this is a good middle ground.

    Hi,

    I’ve considered doing more biking vs. driving my car for commuting but safety concerns are what has prevented me from doing so. With all the distracted drivers out there (texting, etc.), it seems very dangerous to be sharing the road on an unprotected bike. I also lost someone very close to me in a motorcycle accident, which I’m sure weighs heavily on my aversion to bicycles on the open roads. I live in Florida and always cringe when I see bicyclists on roads with heavy car traffic.

    I realize cars are also very dangerous and car accidents occur all the time but I would be interested to see a comparison of biking injuries / deaths vs. cars on a normalized basis for the number of users. In other words, per 1,000 car drivers how many are injured or killed per year? Likewise for every 1,000 bike riders how many are injured or killed per year?

    If we only consider cost savings and leave out the safety aspect we may be encouraging people to take on more risk in order to save money. This may not be the case but again looking at the hard data would help people decide if is right for them. If anyone has something they could share relating to data on this subject I would appreciate it.

    Thanks,
    Dan

        Do you have any safety concerns going 30MPH on a bike? I’ve flipped over my handlebars twice going maybe 15MPH, and both times took me out of the biking game for at least two weeks (plus required a new helmet).

        I think I will stay on a manual bike until I’m old and can’t hit 15MPH w/o an electric bike.

          I would be worried about this too. I had a bad accident on a scooter and broke several bones. I was an experienced driver, and it wasn’t my fault. It would be great to be able to have the boost on a bike as I now have a permanent ankle and shoulder injury. But my ride would take me down the same road I was hit on (with bike lane), so I am not sure the extra speed would be a great plan. Having health insurance and long and short term disability is important if you are the victim of this kind of car accident in my experience, as I did lose my job, and the medical bills were over $300,000. Luckily, those were in place and I am working to get my career back.

        My own gut feel of the bike safety situation is that it will improve as more people are biking. I’m encouraged by things like these electric bikes, which just might help turn the tide in favor of a better biking experience.

          The “Bike Safety” article is the by far the worst article ever written on this blog. If my memory serves me correctly, your own statistics show that travel by car is about 6 times safer than by bicycle on a straight mile-by-mile comparison.

          I don’t even like driving a car, in fact I hate driving in general and try bike as much as I can if I not traveling with my son. But the article is BS because of the way you contort and twist around the statistics to try to support your view. It is so fake.

          It is absurd to assume the average driving speed of a car is 75 mph when most of driving in America is for daily commuting and waiting at traffic lights and, thus, what commute are you thinking of exactly where average speed of the whole trip is 75 mph for an hour? In fact the only reason you choose that speed is because if you do the math and the car is assumed to be less than 70 mph, i.e. say a more reasonable 30 mph, then the car ends up being safer. In fact, the average driving experience or commute in America is more accurately represented in the first 20 seconds in this video:

            When you build cities around the car, those cities are really good at smashing cars into eachother (and into other road users).

            That’s why the normalized death toll in cars in Orlando is like 10x higher than NYC.

            The death toll for bicycles is similar, it drops in walkable, bikeable cities. It’s just another argument in favor of choosing where you live carefully.

            George, everyone where I work tells me cycling to work is dangerous, yet I do it daily, without incidence or near misses on my less thank bike friendly suburb. Also, growing up, riding on the shoulder in traffic was how I learned, at age 10, and rode my paper route at age 12, in the dark, at 4.30am in the morning. Try it, you’ll see it’s not nearly as dangerous as your inexperienced self thinks it is. Also, you sound mad, chill out. You’d be so much happier on a bike with all the exercise and fresh air you get.

        I read this original post, but I think cycling stats are *vastly* under-reported. I was hit by a car on two separate occasions in 2012 while on a bike.

        On one of those two, I was completely fine, got right back up – but the car sped off, and my front wheel was busted. Could have been much worse, I’m fairly certain driver was either drunk or texting or something.

        Second time, got slightly bumped at a stop sign again due to a careless driver looking at cellphone.

        Neither of my two incidents were reported to the police or would appear in the stats. There’s a huge biking community here down in South Florida, and every so often, I hear about a friend of a friend who had a terrible accident (i.e. life changing injury or death) from a bike. It’s enough that I think there must be a few dozen situations in South Florida alone per year. I really don’t buy the national stats, I think injuries on bicycles are much higher than reported.

          I have been “rear ended” in my car twice, and never once reported either accident. What’s your point? Minor car accidents aren’t reported either, so by your logic, car accidents are grossly under reported, which I am sure they are. I have yet to be hit on my bicycle.

      One thing to consider is that the more bikes on the road/cycleway the more drivers get used to it or know someone who rides. Behaviour is better from drivers in areas with lots of bikes – purely my opinion, but if you have lots of kids on foot and on bikes in a suburb, 99% of cars go slower. More bikes = less cars eventually too.
      As a (kind of) bike rider who has had an accident, I would hope that people with electric bikes capable of faster speeds are buying helmets to go with them.

      The whole concept is pretty awesome and new tech that makes it easier and cheaper is going to get more bikes out there. It’s a good thing for overall health, not just your wallets’.

        It has definitely been noted that as the # of cyclist goes up so does cyclist safety. There are also movements afoot to reduce the ‘normal’ speed limit on residential/urban roads from 50km/h to 30km/h (30mph to 20mph). Mostly to increase the percieved as well as actual safety of cyclists and get the women/children/older people feeling comfortable enough to bike again… and it really reduces the risk of death/injury if you are hit by a car going 30km/h instead of 5o…

          Or as the number of cyclists goes up on small roads without shoulders so does the frustration level of drivers. Especially if the fast bikers are passing the slow bikers. You will get more car/bike accidents. The only way to stop the problem is to speed up the bikes or make the cars go very slow. I don’t see them reducing the speeds in town from 35mph to 15mph (or slower).

          Has anyone tried to figure out how much car efficiency is reduced by needing to break a lot due to slow bikers?

      Im 6 weeks into owning my first e bike. Got a Gazelle with Bosch motor made in Netherlands. Its a quality build and will last well into my bike future. First time commuter as well. I love going to work on the bike it makes me feel like a kid going to school even though I’m 53. Im starting to feel the power in my legs but I think its just an illusion as the battery kicks in only when you peddle only. My main issue with the bike commute has always been the perceived danger of getting cleaned up by a car or truck however after 6 weeks I feel very safe I hope thats not an illusion as well.
      On a bike you get to hear the traffic around you and you are a bit higher than a car which gives you very good visibility and peripheral vision comes into play.
      The beloved wife got a Pedago for our weekend commutes and its getting plenty of road time.
      Im starting to look for a bit more speed but I think thats would spoil most of the reasons on started on the blke in the first place.

      I was concerned about this too… and then I actually became a bike rider. I was astonished by just how much cars would go out of their way to avoid me. There’s this very narrow, somewhat hilly, two lane road I have to ride on all the time, and I stay as far to the right as I can to give cars as much room as possible. And yet, cars will go COMPLETELY ON THE WRONG SIDE OF THE ROAD to avoid me. If there’s oncoming traffic, they’ll slow to my speed instead of trying to squeeze by, until there’s enough space to give me a wide berth. And here I thought people would be doing their damnest to run me off the road… nope. I think one of the reasons for this is despite what the media says, most people actually pay attention when they’re driving, and even if they glance down at their phones occasionally, that still doesn’t equal instant death for anyone in the vicinity. It really doesn’t take much effort to drive competently. Remember, the media picks up on unusual circumstances and hypes them up to make them sound common and exceedingly dangerous– that’s their job. Accidents involving distracted texters running over hapless cyclists is rarer than you’ve been led to believe.

      All that said, I typically ride on the sidewalk when possible, even though this is statistically LESS SAFE than riding in the street. In fact, I have been hit while riding on the sidewalk once, but I have never had an accident in the street. But I choose to ride on the sidewalk for the same reason some people choose to pay off debt with the snowball method instead of the avalanche method– while yes, the avalanche method will save you the most money overall, the snowball method is psychologically better for some people, and that can actually mean more to those people than the *real* impact of saving more money. So it is with me and riding on the sidewalk– I know it’s less safe, but psychologically, it *feels* safer to me, and that’s the difference between having a relaxing 26 mile RT commute versus a harrowing one. I consciously trade safety for peace of mind.

    I’ve been looking into electric bikes and thinking of building one from scratch. I live about ten miles from work all highway. I know it’s not ideal but I bought the house last year much cheaper than anything in town with bigger lot and garage. I’ve been more interested in building a custom reverse trike than the e bike. I might suck it up now and go for the e bike. Look forward to your follow up article!

    Very interesting. So I assume that you still peddle and the motor is just boosting your power to increase speed and reduce the effort required by the rider. But do these systems come with an option that you can take over and provide all the power via the pedals and recharge the batteries as you ride?

      No that would defeat the purpose of an assist, if you had to work harder the rest of the time. However the more advanced controllers support regenerative braking, so it uses the motor to brake and recharges the battery while braking just like a Prius.

        To clarify, you can turn off the e-assist and pedal the bike by yourself but you cannot pedal the bike to charge the battery. At least, that’s how it was on the ebike that I tried out.

    • RubeRad October 1, 2014, 8:31 am

      Doing the reverse and charging the battery by your pedaling would be unnecessarily difficult, like riding while squeezing the brakes. (Which is why e-cars use “regenerative braking” — if you’re desiring to brake anyways, might as well capture the energy. Perhaps bikes could use this too, but probably wouldn’t gain enough charge to make it worth it)

      ebikes are heavy enough that they are (reportedly) difficult to ride when the battery runs out, especially uphill. So consider total final weight into any ebike solution, because you don’t want to get stranded somewhere with a spent battery.

      Although that’s probably complainypants thinking… sure bad things happen occasionally, the point is most of the time, you’ll have your battery well charged and experience a speed benefit!

        I’ve had an ebike for two years now and I’m a total convert! The original owner modified it so I can go top speed of 50 kph. I usually pedal somewhere around 24 kph. I get about 100 km per charge. I worried too about being stranded if I ran out the battery. I did, and pedaling a heavier beast (<5km) is really not that bad.
        I felt like I'd finally arrived when a racer pulled up to me and we had a nice conversation about ebikes.

        They can you just need a controller that supports it. You gain about 15% range in the city, depending on riding style.

    • Innkeeper77 October 1, 2014, 11:37 am

      Only direct drive motors can do this, and only some controllers are set up to do it. It doesn’t help range much.. but it is nice to do on downhills. One system, the BionX, can be set up to be in constant regen mode, and different levels. If you are on a long downhill, or want some extra exercise, it can recharge! It would take MANY MANY miles to fully recharge a battery though, which is why many systems ignore this feature. My bike isn’t set up for it, because it is a mid drive, but is more efficient in general with careful usage, so it’s somewhat of a wash.

    The electric bike looks great and like a very excitkng prospect. I think I’m going to stick with my pedal power fir the minute though, for two reasons:

    Still being a way off financial independence it is the cheaper and more badass options, although if you could use the electric bike to replace further motorised commutes there could be an argument for this!

    The electric bike is far more fancy and thus a more exciting prospect for theives in big cities such as the one I live in.

Granted, that almost never happens, so it would probably be cool. Also, I’m not sure how the regenerative breaking would work, if it doesn’t somehow hook up to your breaks to know when you want to slow down. I tried checking out their FAQ, but they just wanted me to email them questions.

      I’m looking forward to this being release and tested by a bunch of consumers before I consider it.

Right now I have a 1.3 mile bike commute down a calm residential street, but I would consider switching to an electric bike if I took a commute much longer than 4 miles. Don’t judge me, the wind and these hills are no joke in San Francisco!!

      One reason to buy an actual e-bike over a kit is the upgraded components. My electric bike has thicker spokes and front fork. My brakes are also heavy duty disc brakes. After riding 2k miles and two years commuting I’m very happy with this bike. The biggest downside to this bike is the weight. This bike is on the heavy side but there are trade offs with everything.

      I ordered my bike off Amazon.com. It’s the Predeco V3 ($1,499). From what I could tell, this is a great deal for the type of battery, motor, and upgraded components it comes with.

      I can, however, see it replacing public transit. That extended range that used to be done with a 1.5hr long bus ride is now done with an ebike. The formly multi-modal trip (bike to the bus/train) now being done exclusively with an ebike.

The city is far but we have a pretty good bus system to get to the core. You still get some exercise walking around, get to read and don’t have to worry about the bus getting stolen. The ebike would be more convenient because there would be no waiting around and it would take you door to door. But, I can’t see the payoff being there for us unless it gets the hubby onboard to go car free. I think he’d still be complainy about hockey gear…

        Andres I do not think the e bike would replace public transit–but rather have the opposite effect. As I read the article & comments I could not help but think that the e bike could be used in conjunction with public transit. The buses here in Calif. have bike racks on the front of them. So– one could peddle bike or e bike to that distant bus stop and take the bus the rest of the way. Or–one could pick up the bus just to avoid heavy traffic/dangerous highways segments of the trip. The e bike would also make commuting by train easier because one could ride the e bike to the station, skip paying for parking, take the bike on the train and use the bike to finish the commute.

      Can you charge at work? 40mile is a bit of a stretch. I get just shy of 30 miles out of a good quality lithium battery (10Ah 48V). Of course you can always get another battery, but that’s the most expensive component.

I always wanted to try commuting on a regular bike, but 20 miles each way seems a bit of a stretch even though I’m in good shape. Lack of any bike infrastructure and no showers at work are the other two major issues. Ebike could help with not getting too sweaty though.

          I commute 20 miles each way to work – no showers. It is a stretch but totally doable. I just bring work clothes to change into, wash my hair in the bathroom sink, cool off for 5 min in the bathroom, put on some deodorant change and good to go. It’s harder when it’s 110 outside but now that highs are in the 90s (only in the 70s in the morning) I’m golden. A full shower when I get home.

          We do have decent bike infrastructure but I always recommend people ride through neighborhoods which should be doable as long as you are not going through an industrial complex.Probably 80% of my commute is through neighborhoods or smaller side streets

            Are you doing it on a regular bike or an ebike? How long does it take you on average to go 20 miles to work and what kind of a cyclist are you? For example, I can ride a couple of hours on my regular bike at a moderate pace without feeling sore but I never ride competitively like the spandex guys you see on the street. Just trying to ballpark the time it would take me to go 20 miles on my hybrid street bike without e-assist (i.e. all muscles, no motor). For example, Google Maps is telling me that my one way trip would be 19 miles and it would take 1 hour and 40 minutes by bike. If that’s true, there is no way I’m ditching my car where it takes me 30-40 minutes door to door. I guess I should just try it one day and see, huh?

              Regular Bike – on Average it takes about an hour 20 minutes to an hour and 30 minutes. Some it has to do with waiting at stop lights and such. I recommend everyone try it at least once. 20 Miles commute definitely doesn’t happen daily overnight (depending on your fitness).

              I had to take a 3 week break because of hours at my job this summer and the fist time commuting again I was sore and tired (but in a rewarding way). But that goes away after a couple rides. Your body adjusts. I build up 2 days a week, then 3, etc you get home and you aren’t as tired.

              I always recommend ride it on the weekend when you aren’t dealing with rush hour traffic or time restraints to get a feel if it is doable or not.

              It definitely takes more time out of my day, but it is worth it for me for many of the reasons others have said.

          Basically your range would depend hugely on how fast you want to go. I get about 30 miles max at about 20MPH. If I slowed down a bit I could go further. Definitely the sweat factor is a big bonus. If you can’t charge at work you could ride in taking it easy and using more power so as not to get sweaty, and then pedal harder on the way back when it doesn’t matter.

      Started doing this a month ago w/ a 40 mile round trip commute. I would do it a couple of times a month on my road bike, but now ride every day with the electric bike. It’s pedal assist, so still a workout, but not so much that you can’t do it every day.

        one more note on the battery range: It’s possible to squeak out a 40 mile round trip w/ mine, but more typical use is 60%+ of the battery for each 20 mile leg. Don’t get a second battery though, just get a second charger. I keep one at work, one at home and just charge on both ends.

    I have a few issues with these. Probably biggest is the weight: for the direct drive I was looking at, the motor alone weighed 14 pounds. Add that to a 20 pound bike and that’s 34 pounds — you’ll likely be using the motor where you used to pedal just due to the weight! Next is the weight limit requiring direct drive. 200 pounds for ride + bike isn’t much to need to go to direct drive. Plus, a 7 gear limit pretty much limits you to bikes from a few years ago — 9 and 11 speeds seem to be the standard these days. Personally, I’d rather buy a used low end Vespa/Vespa-like vehicle — seem much more practical to me, and a bigger step from a regular bike.

      It is true, the bike is heavier now.. but I still find myself riding it without assist sometimes just for the challenge. The effort that used to get me to 20MPH is now good for perhaps 18. No big deal. My strategy has always been “put as much energy as I can handle into the pedals, whenever possible”. Add in electric boost, and you just cover more ground.

      You can use a 9-speed transmission too – it just might require a slight spreading of the front or rear fork area, which you can do easily with a small car jack.

      I thought about the scooter comparison too – used scooters are almost free. But the difference is CYCLING versus sitting passively on one’s ass for transport and losing all the benefit. This is a night and day difference and affects the course of your whole day.

      You can also put the motor in the front: http://www.ebikes.ca/shop/conversion-kits/direct-drive/crystalyte-front-hs-kit-basic-throttle.html
      That’s how I set up my wife’s bike. Works fine and much easier to install.

      But no exercise, no ability to take bike paths, no ability to pass rush hour traffic on the shoulder (depending on your state laws), costs gas, costs insurance. It’s a bit faster, but quite a few downsides.

          Some people don’t like the weight of the motor up front as it makes hopping obstacles harder. Wiring is a bit longer to get from the batter which is usually at the back to the back. On the plus side the bike is more balanced and it has two wheel drive!

          Reply
    • LennStar October 1, 2014, 2:00 am

      The weight certainly is a problem if you have to carry your bike up and down steps.

      While driving the difference is not so big, and with active motor you are better – if you start the motor gives you help, you are actually a lot faster accelerating (depending on setting). When driving at “normal” speed, the wind force is already starting to be the main factor. There is a reason fast drivers like to kiss the wheel ;) Its because the resistance is squared the speed – you double your speed, (additional) resistance 4-folds! So driving at speed 30 takes 5 times the power of speed 15 (+ tire resistance, which means probably #2 at speed 15 and #6 at speed 30).
      And if you have ever seen an electric bicycle going uphills with speed 20+ when you breathless go at under 10, the weight gets pretty ignorable ;)

      My 13Ah battery is about 8 pounds, and the wheel is maybe 10 pounds heavier than a normal wheel (will put more details and weights into next article).

      So including other parts, the bike went from 30 up to 50 lbs – not too big of a deal, since towing 100 pounds of groceries in a 20 lb trailer was already quite practical.

    I think you have your city/hwy MPG backwards. You get better MPG on the highway and worse in city stop-and-go situations.

    This whole post is very anti-mustachian in my opinion. Why spend the extra money on more parts to go wrong and electricity when one can easily power oneself? It’s definitely a giant leap from an SUV,and arguably not as big of a jump to a regular bike, but still.

      Depends what you are replacing. If you are taking the electric bike instead of a regular bike it’s a step backwards. If you are replacing car trips because now it’s feasible to take the bike because of range/gear hauling, then it’s a step forward.

Endurance-wise, I can make the 22 mile round trip commute on my bicycle just fine. Problem is, doing so with any regularity causes me significant pain in one knee.

      MPG is the other way around for electric vehicles. You get better mileage in the stop-and-go city than you do on the highway. Ask a Prius owner the next time you see one.

      I believe his point is to get people who would not normally ride, to hop on and leave the car behind. Yes, if you already cycle, this may seem like a step back, but not everyone is willing to ride 15-20 miles to work. A small investment in an E-bike would pay for itself in a very short time. I just hope he wears his helmet more now and I’ll be looking for him on the Diagonal ;-)

        I’m not a Prius owner, but my dad is, and I’ve driven his a number of times. I could get 50 MPG in the city just fine– but when I pushed it, I got 63.2 on a long road trip from southern Jersey to northern VA. Funny enough, the Prius actually gets its best mileage in heavy (but not stop-and go) traffic– the situation where most cars get their worst mileage. This is because you can use the electric motor and regen a lot of the time, and you’re rarely coming to a full stop, which requires a lot of energy to get back up to speed from.

      The benefit I see is extending the use of a bicycle. I have a bakfiets, and am considering an electric assist conversion to extend my area of use – when loaded it really doesn’t like hills. Even with just 2 4yo kids in it, going over the train bridge to preschool is an effort. With electric assist, I could get almost everywhere I travel on a weekly basis.

The folks I work with think I have lost my mind ;-) It has been enjoyable overall with some comedy along the way (thunderstorms, rattlesnakes, attack dog, etc…). I like the idea of an electric assist primarily due to cutting down on travel time. It currently takes me 32-40 mins one way. I look forward to the next Ebike article! In the mean time, I will be researching to learn more. Thanks for getting the wheels turning with this post.

They go a long ways on a charge and its amazing how effortless it is to cover a tremendous amount of road. The beauty is you are still working out a lot but because it’s not over strenuous to climb hills you’re happy to do it. Love them.

    I built my own electric bike some months ago and am extremely happy with the performance. I used the BBS01 (a mid-drive) which I ordered from greenbikekit.com. I’ve got lots of hills around where I live here in Sweden, and thats why I chose a mid-drive, since they are way more effective climbers. 350w is enough for me, although I did some custom programming back at home to give the drive a slightly better performance than stock settings. I even sold my car because of this thing since I only used the car for getting groceries earlier. Now I use a bike trailer. Tons of money saved, me like.

    I have a 350w (650w peak) electric mid-drive for my three speed gentleman’s bike with a 36v 10ah lithium battery from (Allcell, based in Chicago). My commute is 35 mi round trip over rolling hills and I do it in dress clothes, even in summer, with no sweat. It automatically senses when you pedal and simply makes you bionic. The system is stealth (aprox 28mph top speed with pedaling) and super efficient (though maybe not as much brute power as a hub motor)–40 mi range. Battery will last 30,000mi or more. It’s been a great set up for me. I purchased the kit from Lectric Cycles, based in Arizona. Support is good, LeGrand Crewse is the guy’s name. If I had a shorter commute I might not have considered it, but it sure makes the longer commute more enjoyable, esp in summer. It also gets me to work in less time than riding under human power alone. I can drive the route in 40min, and it takes about an hr to bike it. I would take the electric bike over a moped any day.

    A note: a lot of those kits on eBay are junk. Find a reputable company with good support. And get a well-made battery, as this is often the weak link. Sometimes you do get what you pay for.

I bought it partially as a proof of concept to try to convince my hubs that we would benefit from an electric assist bucket bike of some sort (bakfiets, madsen, kr8, bullitt, etc.) to replace one car and still haul kids and stuff regardless of weather, hills, and/or humidity. However, I love this bike so much I keep thinking of ways to try to weather proof it for the kids (I ride with two) and not bothering to get a bucket bike.

    For those interested in DIY conversions on the cheap, lead acid batteries can be trailer mounted to provide inexpensive capacity while eliminating the concern of added weight (it takes energy to move the batteries around, of course, but you can load up without affecting your bike’s balance).

    Reply
    • Russ Graves October 1, 2014, 11:31 am

      Lead acid batteries are a false savings over a lithium pack. When used under normal commuting loads (which is to say, discharging the batteries greater than 50% somewhat regularly), pack life is normally measured in months. Also, due to the chemistry, you get out a lot less than you put in energy-wise. A lithium pack (I prefer LiFePO4 due to the 1000+ cycles to 80% capacity and lower tendency of catching on fire) is lighter, more powerful, more efficient, and will save you money in the long run, as well as making your bike more enjoyable to ride.

    I have an e-bike. Of course I live in the Netherlands and the speed of those baby’s is definitely limited here. Once you hit 25 k/h (16 m/h) you’re working on just muscle power.

    My husband wanted e-bikes for both of us and I battled him for over a year, saying that my thighs didn’t need LESS exercise… He ‘won’ in the end and after about a week I wished I’d caved earlier. I used to always take the train to visit my family (25 k away). Now all of a sudden, I could go on bike. And what a lovely route! I enjoyed myself so much. Plus, on a 2-way trip I still got plenty exercise!

    And then we had a baby and there’s no transporting one on a bike before they can sit very sturdily in a bike seat. Well mine is 11 months now and she’s almost there. However, I got a bike trailer with a baby seat and was still able to go anywhere safely with the baby in tow since she was about 3 months. These carts can get heavy to pull, especially uphill. But with an e-bike… Whoohoo!!

    I make way more mileage than I ever could have imagined, I still work out (some) and the fresh air and excellent fall scenery keep me happy and healthy. I’ll never get rid of that e-bike ever again!!

    Paid 950 euro’s (about $ 1200) for a previous year’s model, by the way.

    “faster than about 25MPH, as the pre-made bikes must comply with federal e-bike speed limits.”
    Like Sandy in the netherlands, in germany e-bikes (“Pedelecs”) have an upper limit of 25km/h for motor power, after that its your body alone. I always thought that should be upped a bit to 30 (consistent to many town speed limits anyway) for the commuter.

    The reason is the law: You can ride it as a normal bike. No license, no helmet obligation, bike lanes etc.

    If your bike is motor-powered above 25km/h or can go without you inputting muscle power (= self-driven), you need a license, put on a helmet and I think have to use the street.

    So before you buy one, look at your local laws.

    There are 2 things that prevented me from getting one: 1. the price 2) the simple reason I dont drive farther then 3 miles because of my knee. I would be able to go farther and faster here in town without hurts, but I can reach everything and even if it hurts the knee a bit sometimes, the price and the simple fact I have to carry the bike up and down steps every time… no. Perhaps if the price halfed.

    Also from the Netherlands… Here ebikes are coming into fashion particularly for people who are a bit older and have trouble using a regular bike. For them, the extra weight of the bike can be hard to handle at times. Also, for some of these people they can’t actually handle these kind of speeds anymore: their bike goes too fast for them to understand the traffic situation and react to it.

    So there have been accidents where people have hurt themselves or others because of the weight of the bike or because of the fact that they didn’t make the right judgement when “plowing into” an intersection at 16 miles per hour or so.

    Assuming most mustachians are younger and still have enough power in their arms to hold up a bike, and enough brain power to drive at 20 miles per hour or so, they should be fine.

      There are a couple excellent reasons why not to get a motorbike in this scenario-

      1) Cost to operate – an eBike will run on pennies worth of electricity rather than dollars worth of gas. Even when you average out the cost of periodic battery replacement, the per-mile cost is far cheaper than the fossil fuel options.

      2) Noise! eBikes are *very* quiet, if not effectively silent. Not so much for the mopeds of the world…

      3) Emissions – while there’s plenty of pollution coming from our electrical power system as it stands, there are a lot of us going with wind, solar, and other ‘clean’ power options. As those options improve and become more plentiful, the overall emissions footprint of an eBike is only going to get smaller, whereas the 125cc moped you’re suggesting will still dump the same pile of crap into the atmosphere no matter what. Also, many smaller-displacement engines are exempt from the majority of the ‘clean air’ regulations, meaning they actually pollute more than a full-size SUV!

          Insurance again. No insurance on ebikes.

          As for exercise, very difficult to get enough if you don’t build it into normal activities. Sure I could go for a jog but that would be a waste of time if I can combine exercise with commuting

    E-bikes actually terrify me. First I’ll say I’m an avid cyclist, raced for 15 years, spend most of my weekends and all of my vacations cycling, etc. But I live in NYC, where these are supposed to be illegal, and it’s easy to see why. A lot of amateur cyclists and delivery men ride them, and they zip along, going way too fast in the bike lanes, cruising through lights, and I’ve had some scary near-misses. The effect of getting hit by one, especially t-boned in an intersection, would be like getting hit by a motorcycle. And yes, I know I could get hit by a car, too, or another cyclist, but the speed of the electric bikes, and their incognito appearance, puts them somewhere in the middle. I’ve spent time in Thailand where I rode a scooter, and thought they were pretty cool and should be used more in the U.S., so if I were to get on board with e-bikes, I believe they should be catagorized the same way, as motorscooters, and kept out of bike lanes and off the shoulders of roads.

    We’ve got yahoos now on the pathway of the George Washington Bridge cruising along on their e-bikes. It’s a dangerous space, lots of pedestrians and cyclists all trying to navigate a narrow path, then someone comes zooming along on what is effectively a scooter. People who opt for these are often inexperienced cyclists and aren’t great bike handlers. Now they’re going at speeds over their ability.

    I can understand the attraction of using an e-bike instead of a car to run errands 20 miles away, I just don’t believe the safety issues of where they’re being used has been worked out yet, and I see them adding even more chaos to the places where I ride.

    • Rob October 1, 2014, 7:12 am

      I agree KR, in urban areas they can be dangerous. It’s unfortunate, too, because the more they attract attention to themselves with unsafe and irresponsible handling (blowing stop signs, lights, hitting people, etc), the more electric bikes come into the spotlight in a negative light. I am extra cautious to obey all laws and not draw attention to myself or my bike, though it is legal. I think federal law limits them to 20mph in the U.S., though ebikes in Europe have even wimpier limits (might be 25km/hr, not sure). 20mph is a decent speed, and I chose not to go for the 30+mph ebike kits mostly for the legal reasons (thought it would be hella fun). I find my ebike solves the sweat problem and the being-too-tired problem for my commute to work. In urban areas, unless you are using a cargo bike, I find them unnecessary and more of a hindrance.

My query is in terms of bike security (for bikes in general, but particularly for a high-value item like this): what security system would you want on it? A lock, or something more?

My commute is 15 miles each way and I hate taking the car! The bike cost me $3500 to build, but costs just $0.20 to get me to the office and back. It’s halfway to having paid for itself, probably about 2 more years to go.

    So glad you’re doing this! I’ve been interested in electric bikes for years, but never bit the bullet and bought a conversion kit. They seem like such a perfect compliment to the MMM philosophy. It would allow all those people with longer commutes to get to work cheaply and dryly. Now if we only all had protected bike lanes everywhere, it would be a perfect world.

    Funny, I actually *just* bought a secondhand ebike off Craigslist a few weeks ago (a Giant hybrid with a professionally-installed BionX 350W conversion kit) for about $600. There are a lot of questionable electric bikes on CL, but, like anything else on CL, you can get a great deal if you poke around for it.

    I’m finding that the ebike is a GREAT way to lower the mental barrier to getting on a bike, even for more involved hauling or trips when it’s hot out. I can’t help but feel like it’s cheating a bit, but I’m looking at this as a way to help continue to minimize my car usage.

    I biked to a Tesla Motors meetup a few months back. There was a guy there who had 2 electric bicycles to show off. He let me ride them both and they were a blast! Actually more fun than a Tesla, really.

    I rode one electric bike developed by the Russian spetsnaz in the 1990’s. It was too heavy for service though. I could hardly carry it more than 10 feet. But the 2014 bike I rode was way lighter and sleeker. It’s impressive to see how quickly this technology is advancing.

    Hey MMM, I imagine you are already aware of this, but you may want to consider putting in a fuel stabilizer into your car and minivan gas tank if the gas has been in there since April. Great article and yes, electric is the way of the future!

      Hey Kyle/MMM,
      I was actually wondering about this as a tank of gas is lasting me about 1-2 months.

      -Would you still recommend a fuel stabilizer? Which one?
      -Would you take any other maintenance steps in light of very infrequent use?

      I always feel like I’m shocking my Taurus’ system whenever I finally use it :)

    Any would be speedsters looking for the fastest e-bikes would be wise to check their local laws. Unlike regular bicycles, here in Illinois e-bikes are limited to 20 mph… everywhere, always. Getting cited for speeding would certainly take all the fun out of it.

    I do see a place for electric assisted bikes, just not for me. Muscle over motor.

    The Bosch motor on the European bikes looks awesome. It is of the type that just multiplies your input. I think Cannondale is making one destined for our shores this year. These things are pretty pricey which may eliminate the direct savings, but maybe not the indirect through health and fitness for someone on the fence about bike commuting longer distances

    Love the idea of an e-bike – would certainly make biking more attractive given all the hills around here. Anyone bike with kids? I have a 4yo who goes pretty much everywhere I do and he’s just about to outgrow the child seat over the rear wheel. What’s a good next step for a kid who can’t ride his own bike yet?

      In my hilly city, I see a lot of folks biking with their kids on a trailer bike (also known as tag-along bicycles) – if you google those terms you’ll see what I mean. It’s like you chopped the front wheel off a kid’s bike and attached the rest to the back of your bike.

    Just curious MMM, did you research recumbent bikes? They have similar gains like an ebike (according to the tests of the NL cycling union http://www.fietsersbond.nl/de-fiets/snelheid-5-verschillende-type-fietsen-vergeleken), but use the motor over muscle principle. Just enhanced with better engineering (aerodynamics). Should have thought you would have researched it.
    Things like http://www.nazca-ligfietsen.nl/nl/list/models/ kind a stuff.

    This is not even mentioning the ultraefficient option of the velomobile, which only is an option for specific commutes. But when an option, wins from the ebike (any ebike!). The options might be scarce in car-centric US, so I could imagine that bike not featuring in your article – though my boyfriend did ride 3000 miles in US in a month with it without any problems. https://www.youtube.com/watch?v=OxJDxPiANmQ

    Just a minor yet nerdy revision to your numbers. Depending on your weight, a 150W output will get you to about 11-13MPH. This is what can be expected from a couch potato. To go at 20MPH, you need to put out almost twice as much power or some 250W which would be in the range of fit person. Reference: Coggan power chart (google it).

    Incidentally, there’s a much less expensive solution than electrifying a bike which doesn’t require any downtime for charging. It’s called “a used moped” ;-)

    Hi MMM! The idea of an electric bike is really neat. I’m assuming there would be limitations to using it in the winter and with a bike trailer with children in it? My husband and I are currently considering going car less (our 2003 Ford Taurus is starting to have transmission problems) and relying on our bikes and public transportation to get around. Winter is the only thing that is really scaring us. We have a 4 month old and don’t live to far from your home town in Ontario so as you know the winters aren’t very fun. However, we are looking into winter bike tires and appropriate clothing. We really want to make this work! We love reading your blog!!

    • Mr. Money Mustache October 1, 2014, 3:19 pm

      Yeah, Ontario winter can really slow down the cycling unless you live somewhere with properly plowed bike paths or road shoulders. I did manage to do my last 3 years of university in Hamilton with 100% bike commuting, but it was only 5km each way.

      Where I live now it rarely snows, so it’s always biking season – one reason I’m never moving back!

      But combining electric assist with really wide knobby tires would be a powerful thing. You could handle longer distances even in snow.

        I’m a full time bike commuter in up to about -30C and I’ll say two things:

        – Fuck the car drivers, they can wait behind me. The Ontario Highway Traffic Act says I am a vehicle, so I will ride on the road that I pay property tax for. No need for plowed shoulders or bike paths. But at the same time, my protest-style riding may lead to bike paths in the future.

        – Lithium batteries cannot produce as much current when they’re cold. -30C is my rough limit in winter not because I can’t handle it, but because my bike lights (only get 8 hours of daylight so I commute in the dark both ways) cannot last my entire commute past -30C. I assume an e-bike battery would be the same.

    Dear MMM,
    You, sir have recently become my hero. I sold two cars, cut my spendings, started cycling to work on a moderate trafic out of town road 20miles in the dark, rain and 5degrees o Celcium above zero. My wife does 10 miles daily (two times/day actualy) to the kindergarden with a bike trailer and two kids inside. I have also a knee injury and it hurts me if there is a strong wind in front while I bike to work, that is why I started to think about el. Assistant. BUT, I have read your article “Muscle over Motor. It’s more than just an article. It’s a Founding Principle of Mustachianism, because when you embrace it, it adds great fun to your life even while it simultaneously strips away the fat from your physique and your budget. It’s one of the most powerful little three-word sentences you can embrace.” and decided to keep cycling – hoping to build some muscles and get-through the pain.
    But with rhis article, sir, I got confused.

    By the way, bigger part of electricity in the world is still produced by heavilly poluting the Earth by burning coal or producing nuclear waste.. That is why this is not so “green”.

    Sincerely,
    Young, beginner mustachian from Lithuania.

      Thanks Mindaugas,

      You are totally right, Muscle over Motor still applies – see the paragraph where I said an e-bike is NOT actually the ideal addition for my own life, because I can already handle everything by M-bike. This article is for people who are currently unable/unwilling to bike, but ready to dive in if it is a little easier. It is a gateway drug, and they will find themselves riding more after that.

      The electricity consumption of e-bikes is so incredibly low, that it doesn’t matter how it is generated in this case – it is an environmental win. It has an even lower impact than the FOOD a cyclist would normally have to eat to produce the same cycling distance!

      • solid citizen October 1, 2014, 6:28 pm

        I think to be fair, you should also somehow monetize the cost and environmental impact (consumption) of the batteries – production, replacement, and disposal…Battery materials and manufacturing is not very green. I have been waiting for somebody to do the analysis on a Prius or Leaf when taking into account the whole life cycle of the batteries and their total “carbon footprint”… is a Leaf really overall greener than a Honda Fit? Such a comparison is probably hard to make without much assumptions and speculation though.

          You’re definitely right.. there is a bit of that in this article about the Prius: http://www.mrmoneymustache.com/2012/03/20/toyota-prius-ass-kicker-or-trouble-maker/

          The batteries do come with a bit of an environmental footprint. But if you are using the bike to displace a large amount of real car driving (or even enough food eating), it still ends up a big positive because the batteries last 1000 charges x 30+ miles each. This is 30,000 miles, which is an incredible amount of cycling.

      If your knee hurts in a headwind you need to downshift and keep a faster cadence. If your bike is a single speed, invest in gears. If you can’t spin out a 22 by 32 gear even in 50kmh headwinds then you’re gonna have to take the parachute off your bicycle.

      Muscle over motor is great, and bicycles give you the mechanical advantage to use muscle to its maximum potential.

      Edit: Oh yeah, another main cause of knee pain is having your seat too low. Mechanical advantage and all that…

    One thing though, MMM: to you and other Mustachians whose minimal driving habits allow you to stretch a tank of gas for several months, I’d advise only filling up with no more than 1-2 months worth of gas at a time. Gasoline has a limited life, especially with today’s ethanol blends (even when it’s only 10%).

I ride a special petite-frame bicycle, so my options for are limited. I HATE going fast on my bike, but maybe this could be a way to get a little boost. We are a one-car family, so my choices are often “schlep children on bike” or “stay home and all want to kill each other inside of an hour.”

    As someone who commutes 35+ miles a day by bike, I have mixed opinions of the new e-bikes. I live not far from MMM in Colorado and commute to Boulder. This year I have noticed an increase in ebikes on the roads and bike paths. Unfortunately, many of the people riding these bikes lack proper cycling etiquette and safety knowledge. There have been multiple occasions where I have personally experienced these folks trying to squeeze around other bikers and pedestrians and creating unsafe situations for all. Because these bikes go faster than most manual bikes, the folks riding them seem to be overly aggressive in passing and travel at speeds that are inappropriate for the conditions. Moreover, many of these same people do not have a lot of cycling experience and are not always in control of their bikes at these speeds. I would urge folks who adopt this new technology to be respectful of others that use bike lanes and path bikes and to understand cycling etiquette and how to control your bike before cranking it up to 30 mph and trying to pass a group ride of experienced cyclists.

      I definitely agree – they’ll probably start requiring licenses eventually because of just this problem. For now, though, my version of etiquette is to use the super speed mode only on real roads and switch to leg power only on the bike path (unless it is completely deserted as it is during working hours here in Longmont).

    E-bike has come a long way in the last 8-9 years. I did some engineering projects on e-bike during university days and back then it was super cool to work on the e-bike. With the battery technology getting better and better, you no longer need a super heavy battery for the e-bike. This makes life easier when you’re paddling with your own power too. For e-bike to really pick up the price needs to drop further. For now people would just pick scooters over e-bike. I suppose this is similar with electrical cars and regular cars.

    I think this would be a great option for me. I used to live biking distance from work and biked regularly to an office that had a shower if needed. Then, within a few months I both moved in with the new husband and changed jobs – each of which increased the distance with a net result of “too far to bike” – plus I lost the shower. This could get me there in a timely manner and reduce the sweat factor. I am sold :) Admittedly, thinking about using this on ice and snow in the winter make me nervous, but maybe with studded tires I would be okay.

      check for a local bike dealer that sells electric bikes so you can try some out. Your options are a ready-made production bike, or an add-on conversion kit for an existing bike. Bikes with pedal assist can be ridden slowly via both low assist levels and light pedaling (most bikes now work by varying the assist according to how hard you pedal). So if you just want to go easy, there’s no problem doing that. As for the hills, unless they are extremely steep, nearly any current electric bike is likely to be fine for your needs. Details of weight, wattage, amp hours and all the rest matter if you need extended range, are hauling very heavy loads, or are interested in maximum speed/performance. For most folks that just want a little boost you don’t need to worry about all that. Just try out some bikes and have fun choosing.

    I’ve been looking at (read: salivating over) e-bikes for 2 years now. I’ve been in a job that is about 12mi each way, and I work a compressed schedule (Mon-Thurs 10hr days) so I feel like the time burden of biking to work and showering sort of takes away from my time with my son which is the whole purpose of the compressed schedule.

    E-bikes have always been a promise of minimizing that downside. Though, I do wonder how long a 12mi commute would take in the winter when everything is icy/sloshy and you can’t exactly zoom at 35mph on 2 wheels.

    Complainypants aside… I love article and it’s certainly giving me another reason to consider this as my commute.

Once my kid can ride better, then I’ll see if I can get one of these so we can go on longer distance rides. Hopefully, the price will come down a bit in a few years. Yeah, if it’s over $1,000, then I’d probably go with a scooter too.

  • MrBill October 1, 2014, 1:18 pm

    It’s good to see MMM discuss e-bikes.

    A few thoughts:

    1) Reader “Cecile” suggests using an e-bikes are a “big NO” if it replaces a regular bike. I disagree. The marginal value of exercise decreases with the amount of exercise (energy burned) and can easily go negative if it causes over-use injuries. It has also been shown that e-biking has a lower cost of energy than 100% human-power biking, in part because food Calories are more expensive than Calories pulled from the wall outlet. See https://www.ebikes.ca/documents/Ebike_Energy.pdf

    2) In California where I live (and probably other states), any bicycle with a motor is considered a “motorized bicycle” and is by default banned on multi-use paths, trails, and other facilities, except where those paths run immediately on or adjacent to a roadway (such as a bike lane). Although the law was probably written when the only motorization was accomplished with a beastly 2-stroke gas banger, the law makes no exception for an e-bike, whether or not it is speed/power limited. This means you can get busted for riding your e-bike on a bike path, even if you aren’t using the motor. Merely possessing an e-bike on a path is illegal. An effort earlier this year to amend the law to give speed- (20mph) and power- (750 watts) limited e-bikes same access to bicycle facilities as human-powered bicycles recently failed but I expect the effort to be renewed in the coming year, especially since a growing industry’s target market starts out by riding on paths and trails away from auto traffic.

    3) I recommend readers planning to build their own e-bikes with lithium batteries use turn-key battery and charger solutions and avoid using HobbyKing RC packs as shown in the “monsterbike” photo, unless they understand the care and use requirements of lithium batteries and their safety risks. pingbattery.com, em3ev.com (in China) offer solutions price-competitive with HobbyKing and make a good and safe product. Your local ebike vendor will also offer good after-sale service.

    I’ve often considered electrifying a bike but I always come to the same conclusion – for me (a healthy 37 year old man who already commutes by bike about 80 miles/week) it doesn’t make much sense. However, if it will open up new places to use a bike where I normally use a car (like monthly trips to Costco) then it might be worthwhile. Not anytime soon though – still dealing with some pre-Mustachian debt!

      Just because ebikes are capable of 25+ mph doesn’t mean you have to go that fast. Our cars can all get up to 80 on the highway but if we want to maximize our fuel economy, we’ll go much slower, sticking to 60-65 mph in the right lane. Just do the same with an ebike. Use it at a common sense speed and you’ll be fine.

    How long do these Li Ion batteries last for before the range starts reducing considerably?
    Phone batteries start noticeably losing capacity after 18 months or so.
    Presumably a bicycle battery with daily use might do the same?

    Then Li Ion batteries don’t like being fully discharged, so do the bicycle controllers prevent that?

    Reply
    • LennStar October 1, 2014, 3:22 pm

      Modern, good quality Li-Ion batteries shoudl easily give you several years at min 80% even if daily charged and discharged.
      Good quality is the key here.

      And that phone batteries lose after 18 month is either a myth, planned obsolescence (iPhone not long?), bad quality or very heavy/misuse. I had one and the same run for 8 years before it broke down – and that was a very cheap 2001 model!
