Washington, DC e-bike laws (District of Columbia): a 20 mph motorized-bicycle rule, not a three-class system
The District's traffic code calls the category “motorized bicycle”: the vehicle must have 2 or 3 wheels at least 16 inches across, a post-mounted seat or saddle, fully operative pedals, and a motor incapable of propelling it faster than 20 mph on level ground.Council of the District of Columbia — D.C.

Statutory category
Qualifying motorized bicycle
A 2- or 3-wheeled vehicle with a post-mounted seat or saddle for each intended rider, wheels at least 16 inches in diameter, fully operative human-powered pedals, and a motor incapable of propelling it above 20 mph on level ground. The traffic definition expressly excludes electric mobility devices, personal mobility devices, and qualifying battery-operated wheelchairs; the incentive-program section separately defines “e-bike” with the same core seat, wheel, pedal, and 20 mph features for that section.Council of the District of Columbia — D.C.

03 / Where you can ride
Road and sidewalk guidance is direct; paths remain manager-specific
Bike-lane permission is not stated facility-by-facility in the cited sources. DDOT says legal e-bike users on roads are treated like other bicycle users, which points toward ordinary on-road bicycle treatment, but the guide does not separately state a blanket bike-lane rule. Follow current lane signs and traffic controls.District Department of Transportation — E-Bike GuideSpot an error? →
Sidewalks
Generally yes outside the Central Business District. DDOT says sidewalk riding is allowed except in the Central Business District, and a rider on a sidewalk must yield to pedestrians and give an audible signal before passing.District Department of Transportation — E-Bike GuideSpot an error? →
Paths, trails, and property rules
Current path and trail access is manager-specific and therefore unclear as a blanket answer. DDOT's 2024 guide said Class 1 and Class 3 e-bikes were then permitted wherever bicycles were allowed on National Park Service land in Rock Creek Park and the National Mall, but it also warned that trail access varies, some managers prohibit e-bikes or allow only Class 1, and rules are constantly changing. Check the responsible manager and current signs.District Department of Transportation — E-Bike GuideSpot an error? →
The scope of a general local-authority power is unclear from the cited sources. DDOT expressly warns that trail access may vary by locality, neighborhood, and facility manager, so posted restrictions and current property rules remain important; the cited sources do not state a broad preemption rule.District Department of Transportation — E-Bike GuideSpot an error? →
There is no reliable blanket yes. DDOT's 2024 guide described then-current National Park Service access for Class 1 and Class 3 but also said access varies and changes. Check the manager and current signs for the exact facility.District Department of Transportation — E-Bike GuideSpot an error? →
