a starting age for e bikes (like toys have) would be a thing to consider. make it 21+ & limit the capped MPH to 12 MPH. If that doesn't work for the user, then take the bus, get a motorcycle, uber, etc. The close encounters from e-bikes demonstrates the lack of control that the user often has, as speed increases the risk goes up fast. If the user cannot handle a motorcycle/moped they likely are not ready for an ebike.
