In Colorado, electric bikes (e-bikes) are classified into three categories based on their maximum speed and power output:
- Class 1: Pedal-assist e-bikes that provide assistance only when the rider is pedaling and that stop assisting when the bike reaches 20 mph.
- Class 2: Throttle-assist e-bikes that provide assistance when the rider pedals or uses a throttle and that stop assisting when the bike reaches 20 mph.
- Class 3: Pedal-assist e-bikes that provide assistance only when the rider is pedaling and that stop assisting when the bike reaches 28 mph.
Here are some of the key laws and regulations for e-bikes in Colorado:
