Like any other bike, an electric bike can go as fast as you can pedal it or coast it down a hill. But the system's level of assistance depends on which class of bike it is.

E-bikes are categorized into three main classes. Most bike manufacturers and U.S. states, local and other entities have adopted this system, which defines e-bikes as a low-speed bicycle with fully operational pedals and an electric motor of less than 750 watts (about 1 horsepower).

The three classes of bikes are:

  • Class 1: The e-bike will assist when you pedal up to 20mph. Once you reach 20 mph, the motor will cut off and any higher speeds come from your pedaling.
  • Class 2: These e-bikes also provide pedal assistance up to 20mph; they also have a throttle to engage the motor and provide a boost whether you are pedaling or not. The motor stops helping at 20mph.
  • Class 3: Like a class 1 e-bike, the motor kicks in only when you're actively pedaling, but it stops helping at 28 mph.
