Strange that you would choose to ask about this on an anime wallpaper image board's forum of all places ^.^. I wouldn't assume that the people here are particularly more knowledgeable about scooters than the average person. But...

Will you clarify what exactly you mean by "scooter"? There are ordinary mechanical scooters, electrically-assisted versions of those, and "power scooters" designed for road use with higher speed limits... There are even special designs for medical purposes like the knee scooter.
