I would disagree on that. Right now, I work 12.5 miles from my home. I’m slow, so it is an hour and twenty minutes for me to get to work, and two hours to get home. That’s borderline practical as it is. If I worked 20 miles from home, I would see an e-bike as not so much an alternative to a regular bike, but as an alternative to the car I’d otherwise have to drive to make my daily commute manageable.
20 miles on a bike is such a niche that it’s not worth spending public policy time on it because the number of people that will ever do that is insignificant. Making it easier to bike short distances in places where there’s enough density to achieve reasonable mode share is a much better use of public resources (including policy proposals, hearings, etc).

Yes, but the same principle applies to shorter rides. People generally decide whether to bike based on time it takes, not distance. So a faster bike is likely to convince more people to ride.
And the “life is too fast paced” argument is beside the point. For someone for whom biking is transportation, making the commute faster may well give them more time at home to smell the roses (or spend time with family, pursue hobbies, etc.). Making them choose between spending more time or driving to work is not going to make their lives any less fast paced.

ParticipantI don’t think anyone really cares about the speed issue on roads. We already have cars and motorcycles, so if someone wants to get their electric motorbike mojo on, well, go to it. I leave the line between motorcycle/moped and “electric assist” to the powers that be (which is really only an issue for “where the line that requires a class m license, insurance, etc.” is).
When we are talking about non motorized infrastructure like MUPs and bike lanes, I don’t really give a shit if e-bikes are going to get more people “cycling” if its because it lets them go sooper fast and get to work quicker. I’d honestly rather people drive than ride their e-motorcycle down the W&OD at 30+mph.

ParticipantI do want to ask LE, etc to go easy on people who forget they are using an ebike.
For example take the case of an experienced rider, one familiar with all the issues raised in this thread, who, with his daughter, who only bikes on occasion, finds himself in downtown Baltimore, where the bikeshare stations have class 1 pedal assist bikes mixed in with human powered bikes. Though neither he nor his daughter realizes this, and neither notices the lightning bolt on the back fender of one bike. They take bikes out, and fortunately, she takes the one with the lightning bolt. “Daddy, I think this is electric”. After a bit of riding around on streets and bike lanes, they are on their way to Cross Street Market, he is determining the route (both because of biking experience, and because he knows Baltimore a lot better than she does. He ALMOST takes them into a park, the start of the Gwyns Falls Trail – but then is unsure if that really goes where they want, and he decides on an in street route instead. Having totally blanked out on the possibility that taking an ebike onto the trail might be an issue. Fortunately it was (he is sure) a Class 1, and his daughter did not ride THAT fast on it (she sure could beat him up hills, but then he was riding a human powered BIKE SHARE bike) but he really doesn’t know what the rules in Baltimore are.

For short rides, though, the time to get ready to ride, put a helmet on, unlock, find a place to lock up, lock up, take the helmet off, etc reduces the significance of actual speed – which I suspect leads many short distance transportation riders to make different choices of route, of type of bike, etc than longer distance ones generally do. For them the main benefit (and its potentially very big) of ebikes is the ability to ride in “regular” clothes, and lesser need to shower/freshen up at the end of the ride. But a class 1 or 2 ebike easily gets them that.
To the extent that we add more bikes to the trails that enable more long distance riders to ride faster than current average trail speeds, I suspect the less attractive we make the trails to shorter distance riders (and also to pedestrians, though I guess most of those on most trails are recreational), whether human powered, or cautious users of class 1 and 2 ebikes. OTOH very short distance riders may be less likely to rely on trails, simply because going a mile out of your way to get to a trail is more of an issue for them.
OTOH, note also, when you are off trail, if you are even halfway lawful, the stop signs and traffic signals are going to be enough of an issue that a higher maximum speed will be less of an issue. If you are doing a short commute that will be particularly important. As for someone like CvaCalhoun, with a 12.5 mile commute down a MUT, an ebike that enables an average speed of 14MPH (no higher than 15 on the CCT, of course
) would do pretty much what she wants. I think the combo of Hozns and MStone’s points therefore stand – not that the existence of ebikes is a problem, but that the marketing of them around speed does us as advocates more harm than good.

It doesn’t, really. Just like speeding from stoplight to stoplight in a car doesn’t really help you drive a few blocks in the city any faster, being able to go twice as fast on a short trip isn’t going to make much difference compared to other factors (locking up, waiting for lights, etc.) If you want an ebike to save time, the distance has to be long enough for the difference in moving time to be a significant portion of the overall time.
If someone is going 20 miles and isn’t focusing on the health aspects of cycling and isn’t particularly dogmatic about it (because they’re happy to twist a throttle instead of pedaling) then they should just get a motorcycle…among other things, a lot of new routes will open up (VDOT loves to build high speed roads for cars more than it likes to build trails for bikes). But motorcycles aren’t a big fraction of the commuter population either–the deterrent isn’t horsepower or max speed, it’s that there really aren’t that many people who want to be in an open vehicle for a 20 mile commute.

If you’re riding an e-bike that isn’t that distinguishable from an actual bike, you’re extremely unlikely to be hassled. If it operates pedal assist only and isn’t very powerful, only someone who is really in the know is even going to notice.

The baltimore bike share ebikes looked very different from normal bikes, but almost identical (aside from the lightning bolt) to the other baltimore bike share bikes. The baltimore bike share bikes looked like they had a place for an electric motor, though they did not actually have an electric motor. “Why do the non ebikes have to look like this? CaBi bikes don’t” said the alleged bike advocate. “To have more parts in common, I guess” said the so called newb.
(as you can see, I don’t really think we came close to getting a fine for riding an ebike on the Gwynns Falls Trail – I just wanted an excuse to share how the content of a 90 page thread can entirely depart one’s mind when actually riding)

ParticipantMy wife did some bicycle commuting to uptown DC from Northern VA last year., and wants to do more but withan e-bike kit to assist. To test the waters I just got a used 1000 watt,, 48v. rear brushless motor kit off of Craigslist that would have cost $200 new (motor, rim, tire, controller, throttle, cutout-switched brake levers, sundry accessories) (batteries not included). Her bike has 700cc wheels and this wheel/hub is 26″ so I’m putting it on an old Schwinn Frontier (small 15″ frame) bike that I had, with a new, suitable aluminum rack and panniers and some lithium batteries. When i get it hooked I’ll test it out for range and drivability on a run from West Falls church to my work near the Capitol.

Welcome! I bought a refurbished e-bike back in June to start commuting from Vienna to SW DC and lose some weight (about 20 miles each way). It’s been great and I’ve lost ~60 lbs since I started in July. I’d suggest using 11 or 12 gauge spokes for the rear wheel and checking tension every couple weeks as the torque places a lot of stress on them. I’ve broken about 10 so far. Also, since you’re retrofitting an existing bike, ensure that a torque arm is included in the “sundry” items. It will spread torque from just the axle nuts at the rear stays to a second fixed point on the stay. For battery, I got a 17.4AH battery with my bike and that allows me to go back and forth to work on a single charge easily. As I’ve been dropping the amount of assist it gives me, I can actually stretch it out to 2 days back and forth, but I have terrible range anxiety.

That’s impressive weight loss and probably fitness gains to go with it. Good on you. Weren’t you the guy trying to figure out how to haul your required wardrobe on the bike? How’d that work out?
I’m interested in your rig and whatever phog comes up with. I have an old Kona mountain bike that would be a decent platform and a fatbike that is so heavy its like riding in slow motion.
I’ve been watching the Global Cycling Network spin off YouTube channel, Electric Mountain Bike Channel. Both the presenters are accomplished cyclists and motorcyclists, like me. Although the “accomplished” part is questionable.
Seems like I would find a good electric motor on the fat bike a fun half step in between the two. Or put racks and fenders on the Kona and it would be a decent car replacement for short trips to the store or whatever. I’ve been eyeballing the Luna Cycles kits now and then. I balk at the cost, but I spent more than the cost of one of the kits on the rear shock of my motorcycle and forgot all about the expense after the first ride.

If there is enough room in the frame and the axle spacing is compatible you can probably put that 26 inch wheel right in your wifey’s bike with 700c wheels. With as big a tire as you can stuff in there it should have almost no impact on riding characteristics. Except the comfort of a larger volume tire. I am assuming you are talking about a rear hub/motor set up. I have a big 26″ Schwalbe Road Apple tire if you want to try mocking up the fitment of that combination. You can have it if it works. Also assuming disk brakes!

Yep, that was me. I ended up just rolling some dress shirts carefully and bringing them in. When I need to do the full suit dry cleaning, I’ve employed the use of my brother-in-law who works nearby to bring them back in for me in his car.
My bike is a Juiced Cross Current. They don’t make it anymore, but now have the Cross Current S which is better/upgraded. It’s a good bike at a really good price compared to the e-bikes you see in store around here. The downside is that you have to buy direct and with no dealer network on this coast, after-sales support can be tough, but it’s getting better.

We have Luna Cycles mid drive kits on the cargo bikes. We’ve been happy with them thus far.
