Here, if it's got a seat and a motor, it's a moped (even if it can't be pedaled; go figure), and has to be licensed as such. At a certain horsepower or speed (don't have the exact numbers) it's a motorcycle, which requires a different registration and, of course, a cycle endorsement on the operator's license. Kick/stand scooters with motors are considered "play vehicles" and aren't allowed on public streets or sidewalks. This law is, of course, routinely violated, and at best millennially enforced.
