but lobbyists for the cycling manufacturers have pushed hard to err on the side of calling them "bicycles." In Utah, kids have to be 15 before they can operate an e-bike or an e-scooter, and the vehicle must be able to operate without the motor (by pedaling the bike or kicking the scooter). The Surron e-bikes are actually motorcycles in Utah, but very few municipalities enforce the laws around them.
It's crazy that I can get a ticket for testing my kids' 80cc pit bike on our street, but kids as young as 12 are zooming around on unregistered e-motorcycles.
