E-bikes on Open Space

E-bikes on Open Space

Staff created a draft recommendation to allow e-bikes on all regional trails and certain trails on the plains. E-bikes would continue to be prohibited on all other trails.

Draft Staff Recommendation for E-bikes on Boulder County Trails

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

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.

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.

E-Bike Definition & Classes

E-bikes, also known as electric bicycles, powerbikes, pedelecs, or booster bikes, are bicycles with an integrated electric motor that does not exceed 750 watts of power.

  • Class 1 e-bikes provide electrical assistance only while the rider is pedaling. Electrical assistance stops when the bicycle reaches 20 mph.
  • Class 2 e-bikes provide electrical assistance regardless if the rider is pedaling or not. Electrical assistance stops when the bicycle reaches 20 mph.
