So… How Fast Can an Electric Bike Go?
Just like a traditional bicycle, an electric bike can go as fast as you can pedal or coast downhill. The difference is the electric assist, which helps you reach and maintain speed with far less effort. The speed at which the motor assists you depends on the class of the eBike. In the U.S., most manufacturers and states follow a standardized 3-class system. All classes are considered low-speed electric bicycles with:- Fully operational pedals
- An electric motor under 750 watts (about 1 horsepower)
The Three Classes of Electric Bikes Explained
Class 1 eBikes
- Pedal-assist only
- Motor assists up to 20 mph
- Once you hit 20 mph, the motor stops helping
Class 2 eBikes
- Pedal-assist + throttle
- Motor assists up to 20 mph
- Throttle allows motor power even without pedaling
Class 3 eBikes
- Pedal-assist only
- Motor assists up to 28 mph
- Faster acceleration and higher cruising speed
