Boulder City Council voted on June 1, 2023 to allow Class 1 & 2 e-bikes on some Open Space & Mountain Parks trails starting on July 1. Boulder County has multiple government agencies managing trails open to bikes, and each has its own set of rules regarding e-bikes. Here’s an update on what that change will look like in and around Boulder.

There are no singletrack trails open to motorized use in Boulder Ranger District.No e-bikes are allowed at West Magnolia, East Magnolia, Brainard Lake, Peaceful Valley or Lefthand OHV non-motorized trails.No, USFS does not consider E-bikes an assistive device meeting the legal definition of a wheelchair or mobility device and therefore there is not an exception to the Forest Service’s Travel Management Rule.
