With 120 miles of scenic trails, Westminster is a hub of outdoor recreation. As more residents and trail users turn to electric bikes for commuting, fitness, and fun, understanding the rules that keep everyone safe has never been more important. Whether you are considering your first e-bike or already ride one, here’s what you need to know before hitting our trails.
All e-bikes are allowed on roadways and must follow the rules of the road. Westminster follows Colorado Revised Statutes 42-1-102 (28.5), which means only Class 1 and Class 2 e-bikes are permitted on the city’s sidewalks, trails, and parks.
E-bikes are expanding the great outdoors experience for more neighbors, but they also introduce new dynamics to shared spaces. Speed differences, motor acceleration, and varying rider experience levels can create hazards if not managed responsibly.
“We want everyone to enjoy our parks and trails in Westminster, but we need to be respectful and mindful of others and our behavior,” said Westminster Police Sergeant John Wilber. “Understanding and following the rules and regulations protects users and the community, keeping Westminster safe and enjoyable for everyone.”
Before purchasing or riding an e-bike, take time to confirm its class and understand where it’s allowed. Knowing the rules goes a long way toward keeping our community safe. For more information about e-bike safety, visit westminsterco.gov/communitysafety.
Understanding E-bike Classes
Colorado law recognizes three classes of e-bikes, each defined by the type of motor assistance and the bike’s max speed.
These are welcome on multi-use paths wherever traditional bicycles are permitted. Riders must always maintain a safe speed, especially near buildings and high-traffic pedestrian areas, where the limit is 5 mph.
Class 1 E-Bikes
- Pedal-assist up to 20 mph
- Motor activates only while pedaling
- Maximum assisted speed: 20 mph
- Allowed on roads, sidewalks, trails, and parks
- No age restrictions
Class 2 E-Bikes
- Throttle or pedal-assist up to 20 mph
- Motor can assist without pedaling
- Maximum assisted speed: 20 mph
- Allowed on roads, sidewalks, trails, and parks

These pose safety risks or exceed the power and speed limits of shared paths.
