Mopeds are similar but have pedals and can be used as a bicycle. The name itself, Mo-Ped" is a portmanteau for motor and pedal.
Motor scooters are different in that they have a cut out for the rider’s legs/ feet so they don’t have to straddle it the same way they would with a motorcycle. Both mopeds and motor scooters do not require a license endorsement here, while motorcycles, as defined in my original comment, do.
So a moped with a 49cc engine, astep-through design, and no pedals is a moped but a scooter with a step-through design and 49cc engine is a motorcycle?
That’s confusing as fuck lol
