but what’s also true is that anyone can reach those speeds on a traditional bicycle and the outcome of a crash is just as severe.

Except reaching those speeds on a traditional bicycle requires significantly more effort, and is really only possible for adults that are somewhat active. I doubt there’s any 10yo that can reach 30mph on a traditional bike on flat ground

Generally no. In my state that’s illegal, though everyone looks the other way if it’s just kuds on regular bikes. I doubt that’ll continue to be true if kids start blowing past a 30mph though

Can’t that be reported to whatever government agency that made the requirement?
