The difference between electric bikes and mopeds has always been a matter of debate, which is why there are some states that still classify both mopeds and electric bikes as the same thing. However, the main difference between the two is motorized assistance.
On one hand, you usually need to pedal in order to keep the electric motor running in an electric bike. On the other hand, mopeds are low speed bikes with electric motors that are designed so that they don’t require any form of pedaling in order to move.
Unlike electric bikes, mopeds riders are required to register their mopeds and they must carry a driver’s license. They’re also not allowed on bike lanes.
