Maybe just an American thing, but we kind use the term for both but usually call the larger ones "mopeds". If there was a change, I don't think it was too recent either as I had electric (similar to the Bird scooters, but much larger) and manual "scooters" in the late-90's/early-00's.

well the problem there is that a moped is part bicycle.
