Is an e-bike more of a bicycle or more of a scooter?
There are different electric bikes with different experiences.

Some are heavy and powerful, and move with a push of a button. Their pedals are more about legal status than about human power. I'd call them "scooters".

Some are designed to supply power only when the pedals are turning. In that case you have to do a little work for the electric motor to kick in. These are usually called pedelec (from "pedal electric cycle").

Some use sensors in the drivetrain to decide when to apply the power. Those often have a switch so you can get them to drive the motor without pedaling, giving them a "scooter mode".

Some (like the StokeMonkey) apply the power directly to the drivetrain, so you always have to pedal to get them to work. If you're looking for exercise this is a good idea - no temptation to just cruise under power alone.
