I wouldn't call that an scooter. Maybe a moped.
A moped has pedals like a bicycle. That's where the "ped" part comes from.
That was true at the beginning. The idea was that they were a bicycle with an engine to assist pedaling, hence they didn't have to pay taxes or need a licence or insurance. Owners used to remove the pedals altogether, and finally, manufacturers didn't even install them. But the word "moped" comes from "motorcycle" and "pedal". The spanish word is "ciclomotor", where "ciclo" comes from "cycle", that is bicycle with motor. But the legal definition of "ciclomotor" doesn't have to do with the size of the wheel or the fact that they have pedals or not. For spanish laws, ciclomotor is anything under 50 cc irrespective of the vehicle layout. Under that definition, a Cub -100 cc- is a moped by english definition, but not a "ciclomotor" by spanish definition. The same goes for some scooters -mainly italian- that are identical in everything but engine displacement, generally in both 50 cc and 125 cc -125 cc is the limit for the lower permit class, from 16 years-. They are very popular...... for being stolen to get their engines out and swapped into a 50cc model.
