That classification sets 20 miles per hour as the legal limit for Class 1 & 2 bikes. Class 3 bikes are limited to speeds up to 28 miles per hour. The federal law acknowledges and allows for eBikes to travel faster when the rider uses a combination of human pedal and motor power.

Using this 15.5mph limit is designed to reduce the risk of accidents. Remember that anyone from the age of 14 can legally ride an e-bike - a speed limiter means that inexperienced riders may find it easier to control the bike.
