"The peculiar point of the US-configured systems that are now being promoted is that; the rider can only use a throttle up to 20-MPH, however…if you pedal, the PAS will power up the E-bike all the way to 28-MPH." https://www.electricbike.com/28mph-legal-strategy/

"In the State of Texas, electric bicycles are defined as bikes that are powered by an electric motor that have a top speed of 20 MPH on level ground."
