    I know one is in my future. I cant see cycling up the !#@$! Custis Hill for the rest of my life.

    I have seen Freshbikes Specialized on a burrito run to Chipltee . Man that thing does move. But $6K?

    Need to be
    * Affordable
    * Reliable, and
    * Non proprietary (none of this: battery is dead and the company is gone and now by ebike is a paper weight)

    Then you need reputation / word of mouth buzz. Those new wheels that you put on your bike, for I think $800, I think an MIT project… that could be very interesting.

    I’ve said it before and I’ll say it again: an ebike kept me pedaling through my entire 2nd pregnancy. And they keep us pedaling with 2 kids whenever it’s safe to do so. They’re amazing things.

    I often have conversations with non-bike people that start out focusing on the bakfiets — how awesome it is to take the kids around, get fresh air and exercise, not worry about parking or gas — that turn to “oh, I could never push that thing and two kids up hills”. “But you could”, I explain, “because of this little motor.” Most had never heard of the concept of ebikes before, and the idea definitely peaks their interest – especially with city-dwellers.

    I like to think about the future of cycling being in the hands of the “bike-curious” crowd, and e-bikes are a great way to raise their curiosity.

    The “Copenhagen wheel” – I thought that looked really promising too. There’s also the FlyKly which is a very similar concept.

    There are certainly days I wouldn’t mind an assist in the morning when I’m tired, or in the afternoon when I’m dead tired from working and have to think about riding 10mi/climbing 800ft just to get home. Usually if I feel like I’ll definitely be struggling I’ll do a partial commute though. $800 is still a lot of transit trips.

    There have also been times where I’m carrying a small injury or niggle, or toting a larger than usual weight (cargo) and these are the times I think an e-assist would actually be the most useful as an option. If I had more space at home for storage and the technology was more mature I’d probably bite.

    I really hate watching car commercials. They always show the car going super fast on empty roads. What a ridiculous fantasy!

    I think the best combination of bike and electric motor will be mid-drive – motor mounted near the bottom bracket, not inside the wheel hub so regular bike wheels and spokes can be used and maintenance would be easier. Less unsprung weight is also better. That will probably be my next purchase.

    I’ve often wanted e-assist when pedaling 100# of kids & gear on our 60# cargo bike up an 8% incline. But the cheapest reputable kits are $1000-$1500. I wrote the Copenhagen Wheel folks (since it’s “only” $800) and it’s not designed to handle cargo loads like mine, or even IIRC larger Clydes.

    Not having ridden an electric assist bike, I nevertheless detest the idea of throttles and like designs that require pedaling. BionX’s force multiplier + regenerative braking sounds about perfect.

    Once you actually ride electric bikes you might get why the throttle is very useful, and regenerative breaking is a gimmick that doesn’t actually regenerate much of anything to be useful or extend battery life. Unless you coast down the side of a mountain for a couple if hours…

    Please say more. Many of the arguments I’ve read against “e-bikes” center on a perception that they’re essentially dinky electric motorcycles. An “e-bike” with a throttle to many looks to some like a motor vehicle exploiting legal loopholes. Take away the throttle so it’s only e-assist when pedaling and it’s easier to support.

    Also it seems to me that throttles are more likely to contribute to accidents. Sure, they’re probably very safe on open country roads, but most e-assist kits have really short ranges (<20 miles) so these bikes are more likely to be used in higher density areas where one wouldn't use cruise control in a car.

    …also I’ve read (and it makes sense) that throttles for front wheel motors do lead to problems when traction isn’t very good. Suddenly you have a level of control complexity akin to a motorcycle with a manual transmission. That road leads to tests & licensing. With a pedaling sensor, a front wheel motor could be perfectly safe & easy to use.

    I love, love, love my e-bike (Stromer ST1 Elite). When I first bought it I was taking the bus to work and spending an hour and 50 minutes each day in round-trip commuting time. The e-bike lowered that to only 50 minutes for a roundtrip 14 mile commute. I now work in Rosslyn, and even though the commute is only 5.2 miles each way it is reliably much faster than driving (~30 mins in car vs. ~18 mins for bike). The only problem I have now is people stopping me on the street who are REALLY interested in the Stromer and want to ask a zillion questions (this happened twice yesterday on the way home!). I’ll need to factor these delays into my overall commute time :D

    Nice! Might get a few looks from security guards though carrying that briefcase around.

    I continue to love my e-bike for my daily commute and errands. It gets me to work in ~20 minutes when either the metro or driving take closer to 45. I can get there in my suit and tie without sweating, even in the summer. It’s also great for zipping to and from meetings during the workday, which I do pretty frequently. Finally, it makes hauling groceries, kids, trailers and other errands a breeze.

    I also find that it makes me a better behaved cyclist. There’s no motivation to try and maintain momentum, so I stop at every light.

    I built mine on an old mountain bike from an ebikes.ca kit. They aren’t the most cost effective route but offer good parts, turn-key installation, and great support. On the throttle vs. pedalec debate, after trying both I’ve found that I prefer the throttle. I find it easier to modulate the motor during starts to set off smoothly and maintain traction. It’s also helpful not to have the motor kick on if you’re just soft pedaling up to a light while changing gears. I also tend not to use it once I’m up to speed, since leg power can keep you going just fine.

    The Riide bike linked in the article looks interesting. Keeping the design a simple to maintain single speed has a lot of merit. The only thing that troubles me about their design is that the battery is integrated into the frame, so you have to bring the whole bike indoors for charging. I may store my bike in our foyer/living room, but that might not be feasible for many apartment dwellers.

    Felt may have just the thing for you! It’s *this* close to my dream bike, a FAT electric cargo bike.

    I know it has come up in the past, but can we make the e-bike meetup a reality this spring? I think it would be great for those e-bikers among us to meet and for non e-bikers to have an opportunity to check them out/ask questions.

    If anyone wants to test ride our e-assist bakfiets from Rolling Orange (they list it as a bakfiets.nl), let me know. We LOVE it. It is a true car replacement. We basically never use the car within Arlington. (OK, I do to get to meetings in the evening, but only when I’m trying to fit in getting home from work, seeing the kids, and getting to the meeting in a few minutes – or when it’s ICY). I can’t recommend it highly enough for bike-y families. It is just awesome.
