As long as they'r not causing problems for other cyclists And if a frog had wings, it wouldn't bump its ass when it hops. "Other cyclists"? They're not cyclists, they're motorcycle riders, for starters. Now any jackass can zoom down the bike path at 25-30mph, but yeah, as long as that doesn't cause problems...

You realize it is not hard for a cyclist to hit 25-30mph without motor assist, right?

For 10 minutes tops or when falling down an embankment, sure.

>but they're all illegal and you are uninsured when using such a device. My bike is perfectly legal to ride. Plenty of people 'technically' break the law in small ways every day. If your bike looks like a normal bike, and you're not doing outlandish speeds, I'm not sure it matters whether or not your bike is 'technically legal'.

Right up to the point when you cause and accident, it turns out that you are not insured and you are now in debt for the rest of your life. This is not a small matter.

How does someone on a bike 'cause an accident'? How exactly is a cop going to know that you've modified your bike? They aren't tour de france officials. I'd be fine taking my chances. You seem to have a very legalistic outlook that doesn't translate to reality.

Awesome project Jacques! I saw a comment of yours on an article a day or two ago and was hoping to see this pop up soon. I've found the most difficult thing about riding an e-bike is the other motorists have no idea how to react to you. You're not really a regular bicycle anymore due to your speed, but you're also not a motorcycle that deserves its own lane. I have at least one car turn in front of me almost every tr…

Whatever you do in traffic, be very careful. I'm still driving a car and inner city traffic is basically slaloming between cyclists. If something goes wrong, only one of us will end up in hospital. I do also ride my bike on weekends have have been riding a 650cc motorbike for 15+ years, so not at all against 2 wheels. It's just that most people on two wheels seem to have started very recently and they don't know how…

As a cyclist I tend not to care so much about all the mistakes other people do. Realistically it's a very small percentage of people that are new in traffic, the problem is that you usually only see the mistakes people do. You will never see that cylist who changed their pace 20s ago to avoid you.

What has been shown is that people who travel by many different modes; cylists, pedestrian, motorcycle, car, bus etc, are usually much safer and better at navigating traffic. We are all still masters at judging people only based on feelings though that will probably never change.

* You're not really a regular bicycle anymore due to your speed, but you're also not a motorcycle that deserves its own lane.*

If you’re traveling at normal road speeds, wouldn’t you be a (electric) motorcycle? And require lights, tags, and insurance like any other motorcycle?

You deserve your own lane, although the rules vary from state to state. Some states have FRAP (as far right as practicable), others (such as mine) say that a cyclist should take the lane. As a motorist, and cyclist, I cringe when I see a cyclist half-in and half-out of traffic. As a cyclist, I avoid streets with fast, congested car traffic altogether. Fortunately, my locale has a lot of alternatives for bikes, includ…

When getting your motorcycle license here in Belgium they teach you to always take the lane. Ride 3/4 of the way in. If you give the car some space, they'll drive closer to you, try to pass and then get impatient & aggressive when they can't. If you take up all the space they'll usually just accept it. Obviously rules for bicycles may be slightly different but more and more inner city roads here in EU are now clearly…

In the US, we have something called "sharrows" which are a picture of a bike, and an arrow, painted on the street. The arrow is supposed to show drivers the "line" that a cyclist can occupy. Coincident with sharrows, my locale has designated "bike boulevards," that are considered to be preferred for cyclists. I live on such a street, that is a favorite route for riding from a large residential area towards the center of town. So I get to eat my breakfast and watch the bikes go by every morning.

Oh, sure, I'm making it all up. I just spent two months picking apart the Bosch e-bike system, I think by now I know what I'm talking about but feel free to prove me wrong and show me how you're able to get your battery to talk to a Bosch controller without using a Bosch BMS. Hint: you won't be able to, the key is embedded in an NXP processor that has it's fuses blown (both sides, controller and battery) and any kind…

You're in the realm of replacing original parts with the new battery mod. Why not replace the Bosch motor controller with any available motor controller that lets you configure your throttle inputs however you want?

Because that would invalidate the type approval and that in turn would invalidate my insurance.

I didn't see it as absurd at all - there is a huge contingent of bicyclists who should never be on a sidewalk, while at the same time there are massive numbers of casual e-cyclists who should never be riding in traffic. Ann Arbor recently changed it's laws to reflect that - and I think the cyclists who are aware they shouldn't be on sidewalks, and the e-cyclists who stick only to the sidewalks know who they are.

No e-biker should be on a sidewalk. There are informal norms. Cyclists who cycle on sidewalks should be relatively new and should make sure to behave explicitly with all of the rules of the road (ie. don't run a red from the sidewalk as a cyclist, very dangerous. if you must, dismount and walk across or wait for the pedestrian light). Cyclists on the street are generally more experienced and do not have to explicitly…

Not just informal norms, in many states formal laws, just ones that are hardly ever enforced this century. (Many of them on are on the written part of your driving test, though people don't take those often enough to remember their details.)

For example, Kentucky law requires bicyclists over the age of 11 to use the streets. (Prohibits sidewalk usage.)

Washington state law allows sidewalk usage, but also requires wider sidewalks than the Kentucky minimum, and includes a lot of very specific wording about pedestrian right of way on sidewalks (sidewalks are theirs first) and mandate being very careful in overtaking pedestrians and other cyclists.

These particular roads are also closed to normal vehicle traffic (autos and OHV). I will be interested to see if E-Bikes end up being included in the motorized category in the future and therefore not allowed on these roads. There is some debate locally as to whether they should be allowed on normal trails which are already off-limits to motorized vehicles (but OK for standard bikes).

My father actually inquired on this to my local state agency. Technically an ebike is considered a motorized vehicle by the state and is not allowed on trails that prohibit motorized vehicles. I say technically, because I'm pretty damned sure no game warden is going to give you a ticket for riding an ebike. If it looks like a bike, and rides like a bike, and you're not riding above bike speeds, I think you're safe.

Mountain bikes are classified as motorized (WRT Wilderness access at least). If EV bikes are allowed where both pedal bikes and ATVs are not, something is wrong.

That's how it is for S-Pedelecs in Germany.

It weighs half that, including me, and the average speed over a longer trip is about 33 to 35 Kph. In cities you ride just as fast as the rest of the bike traffic, there isn't any point in trying to go faster, and top speed is rarely achieved, you'd need a 100% full battery and a rider in very good condition. More usual you'll be around 35 to 38 kph in open country where there is very little other traffic. My 'commut…

Using my Stromer ST1X — which lacks the top of the line motor of the ST3 and ST5 — I can bike at 45kph at any battery % above 30. I am probably 140kg with bike, battery, laptop, clothes, and stuff. Outside the cities I can go in the bike lane, and I am absolutely twice as fast as most bikes. I live in the Netherlands, so everything being flat helps.

I recently sold my ST2. I could get only 30-60km on a full (1kwh) battery at max speed (46 kmh). But then why would you go below max speed om a 7k bicycle? I got rid of it because it was also very expensive in maintenance, and because cycling on the road slightly slower than cars really sucks (a few too many encounters with aggressive cars). The stromers are near impossible to ride without assist, think because of the regenerative engine. When the battery was empty or I had one of those weird error 18 things I could go abou 17kmh with a lot of effort. I got a vanmoof bike instead niwy, so much nicer. 30kmh, easy to pedal past assist speed cause of light front wheel motor. Lightweight, 500wh battery is pretty ok (also same 30-60km range). Lots of repairs (under warranty) though, build quality is subpar. My 30km commute is 65 minutes now on my vanmoof, where it was 50 minutes on a stromer.
