Regulation for Colorado:
There are 3 classes:
- Class 1: An electric bicycle that only provides assistance when the rider is pedaling; the motor ceases at 20 miles per hour (mph).
- Class 2: An electric bicycle that provides assistance regardless of whether the rider is pedaling; the motor ceases at 20 mph.
- Class 3: An electric bicycle that provides assistance only when the rider is pedaling; the motor ceases at 28 mph. Class 3 electric bicycles must have a speedometer.
Permissible routes for electric bicycles
Class 1 and Class 2 electric bicycles are allowed on the same bicycle and pedestrian paths as conventional bicycles. Class 3 electric bicycles may not be ridden on a bicycle or pedestrian path unless the path is within a street or highway or permitted by the local jurisdiction. A local jurisdiction also has the authority to prohibit the operation of electric bicycles on any bicycle or pedestrian path under its jurisdiction.
