More barriers to cycling means more cars which means more dead cyclists/pedestrians. Help us defeat this terrible anti-safety bill.

I meant motorised bikes in the same speed range as ebikes. Mopeds, not motorbikes. You need a licence, insurance, tag for them. Why not for an equally fast (and dangerous) ebike/pedelec?

F = m * a

Mopeds are at minimum 2-3 times heavier than electric bikes, making them 2-3 times more dangerous since they have 2-3 times more force, without taking speed into account at all. Taking speed into consideration, class 1 and 2 e-bikes top out at 20 mph, while a 50cc moped (based on some preliminary searching, someone please correct me here) tops out at 30 mph, multiplying the force by 1.5x in comparison.

Tell that to the people run over or nearly hit by reckless ebike riders in the pedestrian shopping zone.

For velocity you want kinetic energy .5(mass*V^2)

That’s why braking distance scales exponentially with velocity. 30 vs 20 mph is over twice the energy at the same mass.
