There’s no area in the world that allows e-bikes with more than 750w motors. A 3kw motor is illegal (cf Surron), unless you are talking about an e-moped requiring registration.
The law needs to catch up. There are clearly good reasons for people to want extremely powerful e-bikes and they should be allowed to. They can't be treated like bicycles because they're too fast but aren't nearly as dangerous as motorcycles. We need a new category for light motorcycles.
The real problem, IMO, is that the law is generally not deferential enough to cyclists and already forces them off sidewalks, onto the street, and to follow traffic laws designed for cars. There's not much else to take away, and the rules right now are unreasonable enough that cyclists always break them.
I think what I would like to see are explicit requirements for insurance and licensing for powerful e-bikes, but made significantly cheaper so that people will actually bother. Requiring helmets for the insurance would also make it much more straightforward. We can require them to take the street or a dedicated bike lane and fully mandate that they have to be walked on sidewalks.
I'm not so sure about that.
I don't want a 6000kw Sur Ron riding in the bike lane with me. The whole point of the bike lane was to make a safe space for riding a bicycle. I want the bike lanes to be safe enough for children to ride their bikes in, and having something that powerful in it is not conducive to that goal. They are by and large too fast and too unlike a bicycle for bike lanes. Having things that powerful there is going to dissuade a lot of potential (non electric) cyclists. My girlfriend already gets too freaked out by how fast some of the legal e-bikes in the bike lane go.
Certainly they shouldn't be on the sidewalk. But what does that leave? Just the road. If that's the case they probably need to just adhere to whatever standards the state has for scooters or mopeds. Which probably means some kind of license, maybe registration, and possibly insurance.
But that type of e-bike manufacturer doesn't want to make a light electric scooter that's road legal, they want to make a thing that skirts regulations by being "for off road use only".
And the buyers by and large don't want to deal with license and registration, and certainly not insurance.
Just because people are doing an illegal thing a lot doesn't mean that the law needs to find a way to make it legal.
Why would an extremely powerful ebike be any less dangerous than extremely powerful gas motorcycle?
The real solution people don't want to accept is that ALL non arterial roads in ANY urban/suburban/rural environment should be limited to 30kpmh (and equivalent in NA). And by limited I mean traffic calmed: 1 lane per direction, narrow lanes, raised street crossing, raised intersections, European style roundabouts, the works (Dutch style) - so that people actually respect the speed limit because they don't want to bang their car.
Once that happens, bike stay in bike lanes (or multi use paths with pedestrians) and everything else can go on the regular non arterial roads and stuff that's registered (mopeds and up) and go on any road.
But my "solution" requires major political adoption and probably decades of sustained vision in investment. In places with good governance it will happen naturally and everywhere else will slowly be left behind.
So, literally any bicycle?
Anybody moving significantly faster than the flow of traffic is endangering the rest of the users.
Bikes should be allowed on shared use pathways and all sidewalks larger than 2m should by default also allow bikes.
Mopeds should be banned and fines should be big, to discourage that kind of use.
I propose that in order to be able to leave your house people should have to have a valid reason, have done a course, and apply for a single-use permit.
Because, obviously, people can’t be trusted to do the right thing, ever, and one death in the community, for any reason, ever, is too many.
Fairly sure the Netherlands is a more advanced democracy than the "my freedumbs" US is at this point.
And Dutch infrastructure is also better.
They are called motorcycles. At > 4kw they are that (here). So either you get them registered a such, get a license and insure them, or downgrade them to under 4kw, get a license and insure them as a moped, or downgrade them to 2kw and pedal assist only and register them as a pedelec. All other options is 250w continuous (you can get away with about 500w peak) and pedal assist only.
You are also not insured if you drive an illegal bike on the road.
Opinions differ. I have seen far more accidents with powerful e-bikes than I have seen with motorcycles, and yet there are many more motorcycles.
As a former rider, why? Cars were the most dangerous part, in my experience.
Something that stuck with me from my motorcycle safety course, the speed at which hitting a wall is 50% fatal is 30 mph. Doesn't take highway speeds.
The goal is to protect the regular cyclists and pedestrians who they currently share paths with while trying to not make them TOO unsafe.
What a ridiculous statement.
I don't think there's any inherrent difference, but until the laws catch up the "powerful e-bikes" are clearly more dangerous. Riding a traditional motorcycle requires a license, passing a driving test, and following the rules of the road - none of which are true for e-bikes.
But I'd love to hear why you think the opposite.
Thus, less energy to transmit to a pedestrian
But it's really a moot point because there are essentially zero motorocycles travelling on sidewalks, bikepaths, and trails where pedestrians are going to be concentrated, while it's a free for all for e-bikes.
In general, motorcycle/pedestrian accidents are pretty rare. Statistically, motorcyclists are most likely to injure or kill themselves rather than bystanders.
There are lots of gas powered motorcycles in the bike lanes where I live. Not legal, but nobody enforces it.

In this case it was a bicycle and not an ebike. That said, anecdotally, many ebikes I see regularly travel faster than the people powered versions
If we’re talking about high powered e-bikes, I don’t want them on the sidewalk either. Once they exceed the current regulations they’re in the moped/motorcycle category.
> There's not much else to take away, and the rules right now are unreasonable enough that cyclists always break them.
So what’s your suggestion? Let people ride electric motorcycles on sidewalks? Change the laws so that high powered e-bikes don’t have to follow the rules of the road?
I don’t think the current laws are unreasonable. I live in a place where people routinely ride their e-bikes on the sidewalks and it’s absolutely awful, especially with young children. Every time we go somewhere I have to hold their hands and yank them off the sidewalk at least once to dodge another e-bike zooming past. I can only hope enforcement catches up and starts impounding bikes from people breaking the law and issuing large fines, because I don’t know how else to stop this.
Kids treat them like fast bikes you do not have to pedal. Wiping out on a bike at 13mph is a very different proposition to wiping out on a bike at higher speeds.
I saw just a couple nights ago some kid doing what appeared to be about 40mph on an eBike. Wind in his hair, not pedaling, just blasting it. I am sure new regulations will come to speed limit them, but at the cost of dead and disabled young people.
ETA: I went to go look up laws requiring speed limiters on bikes, and the top hit was about how you can disable them:
https://goebikelife.com/how-to-remove-ebike-speed-limiter/
Article states typical eBike speed limiters are 20-28mph. That is the kind of sustained speed Olympic cyclists can maintain for some period of time, and much faster than kid's toys need to be capable of. And these are the mandated limiters!
Because they have pedals which nobody uses. In theory, it's pedal assist, but kids aren't really pedaling eBikes, they are using them like electric motorcycles.
You might think: Hey, how can you tell the difference between somebody using an eBike with pedal assist if so many of them look just like regular bikes?
I don't really see young people pedaling bikes at all of any kind. It's adults who don't have cars, or adults who are exercising pedaling bikes.
Where do you live - over here(North of England) most kids ride bikes, especially to school. And not ebikes either - actual regular pedal bikes.
This is not the same as being able to go > 60 mph anywhere, at any time, simply by pressing a button.
> When you get a bike like this you deal with the danger and wear protective gear just like you would with any other bike (motorized or not).
This only deals with the danger to the rider - it doesn't address the danger to pedestrians.
Bicycles have long needed a dedicated infrastructure as they are neither cars nor pedestrians.
Yes, I've done this before by riding all the way up a local mountain on a road bike, clad in lycra, then on the way down I went over 60mph. It was terrifying and the physical fitness required to get up there in the first place required months of riding to actually do it. Meanwhile literal kids ride these on pavements, in between people, in cities where pedestrians walk - it's simply not acceptable. And I do own and ride an ebike(limited to 15.5mph) legally.
Therefore, we should count our blessings that it’s not more common, rather than allowing devices that enable it.
Would I have as a kid blasted around at 40mph if I could have? Goddamn right. That's actually my point - I'm not dead or permanently damaged, just the recipient of quite a lot of road rash. Worst injury I ever had on a bike was a broken trapezium, as an adult, for something totally not speed related (~13mph, yes), when a tree fell in front of me and I braked and flew across the handlebars. Game that out doing even 20mph and that's a different outcome.
Classic case of, "I've been there, done that, and this situation is nuts".
And never mind the 45 kph scooters (that regularly do half as much) using the same bike path.
Saw an ebike zip past me at about 40 MPH in a wheelie, little motor screaming, splitting a lane in traffic. (El Camino Real, Silicon Valley). If anything happens ahead of them, they're toast. Can't stop and can't evade.
Now hold my beer...
I've noticed that people seem to believe as long as they bought something it should be safe. If you're smart enough to build something, I have to hope you're at least smart enough to realize that there might be consequences.
Take your beer back, I'm going for a rip next.
Increasing power density (of the motor) just isn't worth much when it does not happen to coincide with an increase in efficiency (and then the battery mass saved for achieving the same range will quite literally outweigh the mass saved by a smaller engine for achieving the same power)
The good news is that those striving for power density aren't really at liberty to completely ignore efficiency in the process because cooling is a key issue for them.
That’s enough power to potentially do that to a full size car frame.
