Have you lived this before? In a city like Beijing there are tens of thousands of people commuting via cheap e-bikes, they are slightly faster bikes, that’s it. Just speed limit them if anything and be done with it (and really, how fast do you think a 2000 kuai e-bike can go anyways?).

I’m not opposed to a speed limit if that’s what you’re asking.

A speed limiter is a much cheaper, more direct way to add safety without mandating anything else about the bike.

I’d be fine with a limit.
