City of Boulder Open Space and Mountain Parks (OSMP) is considering and evaluating the use of e-bikes on some city open space trails.

An online engagement questionnaire was open from July 11 to Aug. 8 to gather community feedback. Staff will use community input gathered to develop a recommended preferred alternative, which will be presented to the Open Space Board of Trustees later this year.

About E-Bikes

An e-bike is a bicycle with an integrated electric motor not exceeding 750 watts of power. E-bikes are treated by state statutes and local ordinances as bicycles. Local ordinance 7941 and State law (CRS § 42-1-102(58)) exclude e-bikes from the definition of a motor vehicle.

E-biking is an activity where participants are propelled by human power and low-powered electric-assist power. There are two classes of e-bikes being considered for use on open space lands.

  • Class 1: Low-speed pedal-assisted electric bicycle equipped with a motor that provides assistance only when the rider is pedaling, and that ceases to provide assistance when the e-bike reaches 20 mph.

  • Class 2: Low-speed throttle-assisted electric bicycle equipped with a throttle-actuated motor, that ceases to provide assistance when the e-bike reaches 20 mph.

Current City Open Space Regulations

Currently, e-bikes are allowed on City of Boulder multi-use paths, except those on open space lands. E-biking also is allowed on Boulder County Parks & Open Space trails in the plains. However, a city ordinance currently prohibits visitors from riding e-bikes on City of Boulder Open Space and Mountain Parks trails – unless the path or trail has been transferred to another city department.
