E-bikes have become one of Boulder’s hottest topics. You can’t ride down the Boulder Creek Path or pass the CU campus without seeing students, commuters, and weekend explorers cruising by with a little assist. They’re fast, convenient, environmentally friendly, and increasingly popular. But in Boulder, where outdoor recreation and land stewardship run deep, e-bikes also come with plenty of questions about where they belong.

If you’re considering hopping on an e-bike in town, here’s what you need to know about where you can legally ride, why the debate is heating up, and how Boulder may evolve in the years ahead.

Where E-Bikes Are Allowed in Boulder

Boulder separates trails into paved multi-use paths, natural-surface City Open Space trails, and regional county trails. The rules differ depending on where you ride.

Paved Multi-Use Paths (Allowed)

Class 1 (pedal assist) and Class 2 (throttle assist) e-bikes are allowed on Boulder’s paved paths. That includes many of the city’s most popular commuter and recreational routes:

• Boulder Creek Path
• Goose Creek Path
• Elmer’s Two Mile
• Skunk Creek and Bear Creek paths
• Wonderland Lake (paved sections)
• South Boulder Creek Trail (paved portions)

There is a posted 15 mph speed guideline on most paths, and riders are expected to slow down when passing others. Boulder’s Transportation Department highlights these guidelines as part of its safety program, which emphasizes shared-path courtesy through its ongoing campaigns documented on the City of Boulder transportation site.

Regional Hard-Surface County Trails (Allowed)

Outside city limits, Boulder County allows e-bikes on certain regional hard-surface routes. These include:

• Rock Creek Trail
• Coal Creek Trail
• US 36 Bikeway
• LOBO Trail (Longmont–Boulder hard-surface segments)

These corridors are part of the county’s broader effort to expand active transportation options, also supported through Colorado’s state e-bike incentive program, which helps increase access statewide.

Where E-Bikes Are Not Allowed

The biggest point of confusion in Boulder comes from the natural-surface trails managed by Open Space and Mountain Parks (OSMP).

E-bikes are not permitted on any OSMP natural-surface trails. That includes favorites such as:

• Chautauqua & Flatirons trails
• Mount Sanitas
• Bear Peak and Green Mountain trails
• Doudy Draw and Marshall Mesa
• Enchanted Mesa and Mesa Trail
• Walker Ranch

The only exception is for qualifying mobility-assist devices under ADA rules. OSMP’s reasoning, according to their official regulations, highlights wildlife protection, trail congestion, and maintaining traditional trail experiences.

Why E-Bikes Are So Controversial in Boulder

E-bikes sit right at the center of several competing priorities in town. Supporters argue that e-bikes reduce traffic, expand access for older adults, help students live car-free, and support sustainability goals. Boulder’s busier paths show more residents choosing them for commute and recreation, which aligns with the city’s climate action plans.

On the other hand, opponents worry about speed differentials with pedestrians, wildlife disturbance on natural trails, and increased crowding. Some residents and hikers express concern that allowing e-bikes on narrow trails could change the quiet, traditional feel of the foothills.

With Boulder being both a tech-forward community and a fiercely protective outdoor town, the debate naturally runs strong.

Boulder’s Best Legal E-Bike Rides

If you want a scenic, legal ride, Boulder offers plenty of great routes without entering restricted terrain.

Boulder Creek Path remains the most iconic, offering a smooth ride through the heart of the city. Goose Creek connects multiple neighborhoods with CU and downtown. The US 36 Bikeway gives riders an impressive long-distance option all the way toward Denver. For something quieter, the Rock Creek and Coal Creek regional trails offer rolling landscapes with fewer crowds.

These routes allow riders to enjoy Boulder’s beauty while staying fully compliant with city and county rules.

What’s Next for E-Bike Policy in Boulder

Boulder is evaluating how e-bikes fit into its long-term transportation and sustainability goals. With rising commuter traffic, CU enrollment, and more residents seeking alternatives to driving, e-bike access will likely continue evolving. City staff have already launched data review efforts on safety, traffic density, and climate benefits, and future pilot programs are possible.

Where this conversation goes next will define how Boulder balances innovation with conservation.

Riding With Courtesy and Kindness

Whether you ride a traditional bike or an e-bike, Boulder’s outdoor culture thrives when everyone respects the trails and the people on them. Slowing down, passing carefully, and staying aware of where e-bikes are allowed goes a long way in keeping the community moving smoothly.
