I tend to agree with comments that point out that 'modern' e-bikes are really electric motor cycles or the original "MoPed" from the 60's. And they have the same appeal, relatively cheap to operate, fit in between regulatory categories, don't require a garage to store, Etc. E-scooters aren't much better (just worse kinematics). That said, I never thought the Segway was ever going to be more than a 'niche' product whereas I had already lived in a city[1] with thousands of mopeds. To the extent they are embraced by urban planners with reduced parking mandates and their own roadways I think they are a net win for cities, when they terrorize pedestrians on sidewalks, not so much.

I think that the Class 1 and Class 2 and Class 3 regulations when properly followed tell you what you are getting. Since this is Class 3, it really is close to a Moped and has a lot more restrictions depending on your area similar to a motorcycle but still allowed on city streets without insurance in most places in the USA, but often has restrictions in parks etc.

The problem is that many other manufacturers have “selectable” class which really is meaningless and doesn’t really tell you what you are buying and often times is really close to a motorcycle. But unlike cars you can easily import bikes that don’t conform to the regulation so many don’t.

If I were buying a bike for my young child I would stick to class 1 or 2.

I agree, the classifications are pretty solid when followed and I'm with you on class 2 being the right pick for most people - But I'd argue they're too complicated.

I think it's also a social issue right now, there's very little general information provided to bikers (ex - most people don't even know these classifications exist, and can't remember them if they do), and not a large enough chunk of the population is biking yet to get a general consensus on "acceptable" behavior.

Couple that with low enforcement, and it makes sense a fair number of people are just clueless.

Just simple things like "bike speed limit" signs on trails/paths would probably help a lot.

I have a class 3 ebike, and I'd still 100% prefer to ride it on a trail with a speed limit of 20mph instead of having trying to mingle with cars on even moderatly busy streets.

The laws should let bikers understand the desired behavior, and allow them to self-regulate.

Especially given that this isn't in the same risk category as larger vehicles (e-bikes are half the weight of mopeds, and 28mph is very different than 45)

Then give folks tickets. They're too useful to go away - we'll get it figured out.

I think the MPH limit for ebike classification makes sense. But why do they need a 750W limit? Whats the harm in a motor putting out 3000W to get a loaded cargo bike up a steep hill at 8 MPH.

My opinion is been that 747’s, cars, trucks, bikes, E bikes, an even pedestrians should be regulated on kinetic energy - basically their ability to do harm to others.

My fear is that without it, regulatory arbitrage will turn every inch of land that doesn’t have a building into Death Race 2000. Cars are not allowed on sidewalks to protect friends? No problem - here’s an electric motorcycle disguised as a bicycle. Hi
