The Dutch seem to just do the sensible thing and have mobile e-bike dynos. If they suspect the bike is not properly regulated, they'll test it and keep it if it fails.

AFAICT, lots of people in the Netherlands also complain about kids on fat tire ebikes that look like motorcycles.

OTOH people in 80's complained about kids on BMX bikes terrorizing the neighborhood, and those things were slow.
