Staff Recommendation for E-bikes on Boulder County Trails

Staff considered public input, community input, trail characteristics, and resource values in the draft recommendation. The recommendation is summarized below.

Staff Recommendation

Based on the change in state law, input from the public, trail characteristics, and management considerations, staff recommends:

  • Allowing class 1 and class 2 e-bikes on regional trails and on all trails on the plains where bikes are allowed, with the exception of three trails: the Coalton Trail, Mayhoffer Singletree Trail, and the Boulder Canyon Trail, as requested by City of Boulder.
  • Prohibiting e-bikes on all foothill and mountain trails.

Staff proposes this recommendation as a pilot program to run through 2019. This will give staff an opportunity to conduct targeted studies on e-bikes at selected parks and trails in order to assess the pilot program.

POSAC Meeting

On June 28, the Parks & Open Space Advisory Committee voted 3-2 in favor of the staff recommendation.



E-bikes are classified as motorized vehicles and are only allowed on motorized trails, including Bureau of Land Management (BLM) and National Forest (USFS) lands.


E-bikes are classified as bicycles and have the same rights of the road as traditional bicycles. In 2017, HB17-1151 Electrical Assisted Bicycles Regulation Operation was passed. The bill changed Colorado bike law, specifically C.R.S. § 42-4- 1412, to allow Class 1 and 2 electric assisted bicycles on multi-use trails unless explicitly prohibited by the managing land agency. The bill gives local governments the authority to allow or prohibit the use of specified classes of electrical assisted bicycles on pedestrian paths and bike paths.


Local governments have the authority to authorize the use of e-bikes on bike or pedestrian paths. Under the current Rules and Regulations, e-bikes are prohibited.

Individuals with Mobility Disabilities

Individuals with mobility disabilities are allowed to use Other Power-Driven Mobility devices (OPDMDs), which can include e-bikes, on all trails open for pedestrian use unless a particular trail has been designated as inappropriate for use by OPDMDs based upon the assessment factors found in 28 CFR § 35.137(b)(2) of the Americans with Disabilities Act. A current list of trails where OPDMDs are allowed is available on the Accessibility on Open Space page.
