Colorado State Electric Bike Laws, Definition & Legal Operation

Definition of Electric Bike:

The state of Colorado (CO) statute has three classes of electric bicycle: Class I is for pedal assist with maximum of 20 mph electric assist. Class II is for bikes that provide electric power whether or not the rider is pedaling, but stops providing power when the speed reaches 20 mph. Class III is for bikes that continue providing electrical power up to 28 mph.

Licensing and Registration:

Electric bikes in Colorado do not require licensing or registration. However, Class III electric bikes can only be operated by those who are aged 16 or older.

Helmet Law:

Colorado requires a helmet for both rider and passenger for electric bikes in Class III only. Certain local ordinances do require helmets for persons aged 18 and under.

Where to Ride:

Electric bikes are allowed on roads and bike lanes. Electric bikes are allowed on bike and pedestrian paths, but may not engage the motor unless allowed by local ordinance. The City of Boulder is currently the only city to allow motors to be engaged on bike paths. Electric bikes must be ridden on roadways and are prohibited on sidewalks. Also note that Class III electric bikes are restricted to riding on public roads only (no bike paths or pedestrian paths).
