I wish I had U.S. "e-bike class issues" headache here in Europe...
A typical conversation when I am at stop and someone spots the number plate on my Vado:
-- A registered bike? How come?!
-- It is a speed e-bike that is assisted up to 45 km/h... Technically, a moped.
-- Meaning, you de-restricted it?
-- No, it is a speed e-bike, made that way by the factory. It would not get the number plate otherwise...
Now, it is technically infeasible to remove the number plate support, as it has integrated rack, tail-light and STOP indicator. And the number plate is permanently lit.
