Where to ride in Boulder County

Boulder Creek Path is the city's main east-west spine. It is a 5.5-mile multi-use path from Boulder Canyon to the Stazio Ballfields just past 55th Street, passing the Main Library, Civic Area Park and the Boulder Dushanbe Teahouse. The City of Boulder manages it. Class 1 and 2 eBikes are allowed. Class 3 is prohibited on all multi-use paths and open space trails the city manages. The speed limit is 15 mph, and 8 mph in crosswalks. If you plan to commute downtown, think about which class you buy. Details are on the City of Boulder Boulder Creek Path page.

Boulder County Parks & Open Space manages the regional trails. The LoBo Trail is a 12-mile system through Gunbarrel and Niwot that connects Boulder and Longmont. E-bikes are allowed except a short signed area near Twin Lakes open space, where HOA restrictions apply. Coal Creek Trail runs 14 miles from Superior through Louisville and Lafayette to Erie. Rock Creek Trail runs 12 miles from Coalton Trailhead in Superior to Lafayette. Class 1 and 2 are allowed on all of them. See the Boulder County eBike rules for open space for the full list.

Not every county trail is open to eBikes. Boulder County bans them on foothills and mountain trails, including Anne U. White, Bald Mountain, Betasso Preserve, Caribou Ranch, Hall Ranch, Heil Valley Ranch, Mud Lake, Ron Stewart Preserve at Rabbit Mountain and Walker Ranch. The plains are different, because designated plains trails such as Pella Crossing, Walden Ponds and Niwot Trails allow Class 1 and 2. Commissioners approved that on November 13, 2019, after a pilot. E-motos over 750 W or 28 mph are prohibited, ticketed and fined. Read the Boulder County Parks & Open Space eBike page before a new ride.

The City of Boulder also opened specific Open Space and Mountain Parks trails to Class 1 and 2 eBikes on July 1, 2023. They sit in East Boulder and North Boulder, and include Cottontail, Sage and Wonderland Lake. No eBikes go where bikes are already banned, and bikers yield to hikers and horses. For Class 3, the US 36 Bikeway is the one county trail that allows it. It runs 18 miles between Denver and Boulder. Start with the Boulder OSMP eBike guide for the trail-by-trail list.

eBike rules in Colorado

Colorado defines an electrical assisted bicycle in C.R.S. 42-1-102 as a two or three wheeled bike with fully operable pedals and an electric motor not over 750 watts. There are three classes. Class 1 gives assist only while you pedal and stops assisting at 20 mph. Class 2 can assist without pedaling and also stops at 20 mph. Class 3 assists only while you pedal and stops at 28 mph. A bike that has been modified out of every class, or that is built or sold to be easily configured past the class limits, does not count as an e-bike.

Under C.R.S. 42-4-1412, e-bike riders have the same rights and duties as drivers, subject to local ordinances. Class 1 and 2 e-bikes may use a bike or pedestrian path where bicycles are authorized. A local authority may prohibit them there. Class 3 e-bikes are not allowed on those paths unless the path is within a street or highway or the local authority permits it. Riders under 16 may not ride Class 3, though they can be passengers on a bike designed for passengers. HB25-1197 was signed May 28, 2025 and took effect Aug 6, 2025. It adds seller disclosures and multiple mode e-bike rules. From Jan 1, 2027, multiple-mode labels must show the highest class or each class.

Colorado has no statewide helmet rule for Class 1 or 2 riders. Class 3 operators and passengers under 18 must wear a CPSC or ASTM bicycle helmet with a chin strap. Compliant e-bikes need no license or registration. Labels must show class, top assisted speed and wattage, and must be updated after any modification (C.R.S. 42-4-221). Under HB25-1197, falsely labeling a non-e-bike as an e-bike is a deceptive trade practice. For more detail, see our guide to Colorado eBike laws.
