Class 1: Colorado statute recognizes Class 1 as pedal-assist only up to 20 mph, with the standard e-bike power cap framework.
Class 2: Colorado recognizes Class 2 as throttle-capable up to 20 mph assisted speed.
Class 3: Colorado recognizes Class 3 as pedal-assist only up to 28 mph and requires additional equipment such as a speedometer.
Helmet laws: Colorado requires helmets for riders and passengers under 18 on Class 3 e-bikes; no statewide adult helmet rule for Class 1/2.
Age restrictions: Class 3 operators must generally be at least 16 in Colorado, with limited exceptions for passengers.
Road access: Generally permitted on streets and bike lanes when vehicle qualifies as an e-bike under state law.
Trail access: Class 1 and 2 are generally allowed where bicycles are allowed, while Class 3 is usually restricted from many bike/pedestrian paths unless locally authorized.
Sidewalk rules: City ordinances control sidewalks; mountain towns may differ from Front Range cities.
Important notes: See Colo. Rev. Stat. §42-4-1412 and related e-bike articles. CPW, USFS, and ski-town governments each post different trail rules. Educational summary only—not legal advice.

Front Range cities overlay class limits on state path defaults
Colorado generally allows Class 1 and 2 where bicycles are allowed, with Class 3 more restricted on paths unless a local authority says otherwise. Denver and nearby trail agencies post their own e-bike signs — those posted rules control even when the statewide summary looks permissive.
