> Many high power ebike enthusiasts (for example “High Voltage DIY Electric Bikes” channel on YouTube) argue that these low legal power limits actually make e-bikes less safe, as you need a good 2-3kw to actually ride with the flow of traffic. At US or worse UK power limits, you don’t get enough of a boost for that and you’re more likely to get hit from behind.

Those "High power ebike enthusiasts" are actually "small electric motorcycle" enthusiasts.

The point of the regulations is to keep the power levels within the range of what's expected for a bike.

I'm fine with a separate class of regulations allowing higher power, but only if those vehicles are easily disallowed from bike trails. If the goal is to ride around with cars in traffic all day, it shouldn't be a problem to be banned from bike trails. There's a real problem of overpowered DIY or hacked e-bikes tearing up trails everywhere and getting out of control.

3kw is 4 horsepower. It's more than even the world record for peak human power output and far more than any human can sustain.

I think it's cool that people build these high power machines, but let's be honest about what they are: Electric motorcycles, not bikes.

Trails and bike lanes too. If you want an electric motorcycle - get one, get a license, register it and stay the fuck off the bike paths.

Well put. I wouldn't want to ride with my kids with a 3000w bike breezing pass me in the bike lane at 45km/h

Did you know lots of people can ride a road bike under 100% human power at 27MPH+ (45kph?)? Parent comment doesn't align with commonly observed reality.

Iron Man participants regularly ride at an average speed of 24mph+ continuously for 112 miles in extremely harsh conditions (Hawaiian heat).

Also, over the course of many thousands of miles I've never observed any cyclist riding past vulnerable children at these speeds. What is the problem exactly? People going "fast" on a 50lb bicycle with nobody else around? How is this a threat?

Most people aren't out to get you, especially bicyclists.

If you want to direct energy towards something, please send it towards the inconsiderate cars vectoring a 3ton+ vehicle at 25-75MPH even when they see a person in the road ahead. It's sad when a human is struck by a vehicle.

*I usually don't respond to comments like this one but after being hit by a car while I was in the bike lane on Veterans Blvd in Redwood City, CA in 2018, who didn't bother stop (or even notice they'd hit and knocked me down?), it's a bit of a sore spot. The difference between a car and a weapon is what, exactly? Even an overpowered e-bike is nothing compared to any of the tens of thousands of cars who kill and maim cyclists and pedestrians in the U.S.A. annually.

Thanks for the pile-on, but this is completely irrelevant to what I was posting about. The DJI kit is very heavy (in KG) to deliver a comparatively puny amount of power. That is the interesting point, not the legality of an e-bike I purchased 5 years ago and haven't had any trouble with. Just saying.. be cool.

P.s. parent has heavily edited their comment to not resemble the original comment. For whatever it's worth, I don't have any particular agenda except to share information. I'm logging off for the evening, because this is peak nonsense.

Maybe technically correct, but these are being sold as bicycles. I think the biggest distinction between most (but not all) high powered ebikes and electric motorcycles is that most of the ebikes can be powered by pedaling (except bikes like the Sur Ron).

We can make a legal category for "electric motorcycles with pedals" or we can call them high powered electric bicycles. I don't care so much what we call them as long as we recognize that this type of vehicle is extremely valuable in fighting climate change and building more walkable cities with less need for automobile infrastructure. If everyone could legally ride a 2kw ebike around town with some nice panniers or a rack for cargo space, so many automobile trips could be eliminated.

When you say trails, I could agree on dirt trails where erosion and environmental damage is an issue. But as we build out better bicycle infrastructure around the country, we have more and more dedicated paved bike paths. It would be absurd to me if bikes like my 1.5kw ebike were barred from paved bike paths. And note, it already is! Most of the paved bike paths around Oakland and Berkeley are legally restricted to class 2 ebikes. My bike is beyond class 3, and so illegal both generally and on these paths. But I don't think it should be! I have been bicycling for almost 40 years, so I am extremely respectful of other people and I don't want to blow past anyone. Maybe there need to be more fine grained laws around etiquitte, or maybe we need to expand our notion of bike paths to include 3kw ebikes. There must be some middle ground between surface streets with 4000lb vehicles and bike paths that are only for low powered or human powered bicycles.

But my broad point is, these vehicles are extremely important to a world with reduced carbon emissions. They are much more useful than a regular bike (which I also ride quite a lot) for transportation purposes, and so better as a car replacement. They take less resources and emissions to produce, they use less energy to move a person, they are safer for pedestrians than automobiles, appropriate infrastructure takes up less space, etc etc etc.

The attitude of "that's a motorcycle! you had better keep that as far away from me as possible" is a negative-focused view on what can be an extremely transformative technology.

I know there are assholes and irresponsible people, and actually a good friend of mine broke their leg in an ebike-on-ebike collision in the UK on a legal 250w ebike, so I understand that injuries can still happen. And I absolutely do not want assholes blowing past old ladies or parents walking their kids in strollers.

But we MUST consider the real value this new type of machine has to offer, and genuinely take time to consider how they should be used. The knee-jerk claim that it is just a motorcycle is missing that in reality they are a new class of vehicle. Similar to a bicycle and similar to a motorcycle, but lighter than one, easier to handle, and I would argue much more useful.

So sure, let us create regulations around them. But let us make sure we allow them on appropriate bike paths, and build the right infrastructure to take advantage of such a useful new type of machine.

3kW I assume?
