In my state, MD, there is no age limit for class1 and 2 e bikes. For class 3 e bikes you have to be at least 16. I think that is reasonable. My 17 year old son has a Ride1up 500. He also has a DL and has good judgment. He does not ride above 20 mph and often rides his e bike with no assistance. He can ride it to school, rather than take the bus, if they re-open in person school in my County. He would need a good lock and an alarm.
