My "old school" brushed motor electric bicycle can do 25mph, without pedal assitance.
Apparently they have new brushless motors that fit into the rear hubs that can do 30+ mph. Beyond that it is only a wind resistance problem. There are hobbyists with 50mph electric bicycles which sounds crazy.
- masklinn 13y agoEven under lax US federal law, these are not "bicycles" and are classified as motor vehicles. Public Law 107-319 defined "low-speed electrical vehicles" and altered the motor vehicle safety standards to make these low-speed vehicles not considered motor vehicles. Low-speed electrical vehicles are defined as: 1. two- or three-wheeled 2. fully operable pedals 3. less than 750 watts (1hp) 4. maximum speed (power-on-demand) of 20mph on a level surface with a rider of 170 pounds If it goes at 50mph, it's an electric motorcycle.
