Cross-posting my comment from the other community:

I think what our mate Darin is referring to by “e-bikes” is throttle-operated, no need to pedal, capable of going 30-60mph electric motorbike which, like any other motorbike, you need a licence and protective gear to ride, and no, they’ve got no business being in the bike lane with people noodling along at 10-15mph, and definitely not on the pavement with pedestrians.

Unfortunately, Darin is an idiot who can’t string a sentence together and so he’s just told everyone that my electric assist pedal cycle, top assisted speed of 15.5mph, no need for a licence or insurance, is also illegal. Thanks, Darin.

This House of Commons briefing from 2019 lays out what the issues are with e-scooters, in that because they’re not legally classed as a bicycle, they have the same legal requirements as a motorbike, which is clearly nonsense for a scooter with a top speed of 15.5mph, however, the law has not yet caught up with reality. Since that briefing was written, various trials have started in cities with hired e-scooters provided by third parties to see how the law needs to be updated and what needs to change in order to make them legal on UK roads, but the trials seem to just keep getting extended with no conclusions drawn. As we’re currently in election purdah, nothing’s going to happen until July anyway, and I highly doubt that “sorting out e-scooter legality” will be top of the new government’s priority list.
