Boulder's extensive bikeway network — including the Boulder Creek Path and protected lanes on Folsom and 30th Street — operates under Colorado statewide vehicle code plus local rules on speeds, e-bike classes, and pedestrian yielding on multi-use paths.
Boulder maintains over 300 miles of bikeways including the flagship Boulder Creek Path, Bear Creek Path, and protected on-street lanes installed under the Living Lab program on Folsom and 30th. Cyclists must follow Colorado Revised Statutes Title 42 traffic laws and yield to pedestrians on multi-use paths. E-bike classifications follow CRS §42-4-1412 (Class 1 pedal-assist up to 20 mph, Class 2 throttle up to 20 mph, Class 3 pedal-assist up to 28 mph) with restrictions on certain multi-use paths and open-space trails. Boulder Open Space prohibits e-bikes on most natural-surface trails. Helmets are required for riders under 18 in some contexts.
Failure to yield, riding the wrong way in protected lanes, exceeding posted path speeds, or operating an e-bike on prohibited trails can result in BPD citations under state and local code.
