Boulder Is Consistently Rated as One of the Best Places to Bike in the Country
With an active culture, more than 300 days of sunshine and hundreds of miles of bikeways, Boulder is a great place for bicycling.

Get Around by Bike
Parking your bike
-
How to Park
- Park your bicycle in a designated bike rack whenever possible and avoid parking your bike on trees, signs and other structures.
- Lock your frame and wheels to a dedicated bicycle rack using a high-quality U-lock or heavy-duty security chain. Only use a cable as a secondary lock to secure wheels to the frame. Take easily removed parts with you – lights, air pump, bags, etc.
- Always lock your bike on your car rack and at home – bikes can be stolen from garages and yards.

Where to Park
- Free bicycle racks are provided across Boulder to make it easier and more secure to park your bike.
- Free, secure bike parking is available inside three parking garages downtown:
- Spruce Street/11th Street Parking Garage.
- Pearl Street/15th Street Parking Garage.
- Walnut Street/14th Street Parking Garage.
- All official Open Space and Mountain Parks Trailheads also have bicycle racks.
Dismount Zones
Riding bikes and other wheeled devices on the sidewalk, except for accessibility purposes, is prohibited downtown on and around the Pearl Street Mall and in the University Hill commercial area. You must dismount these wheeled devices in Dismount Zones.
Outside of dismount zones, bikes can be ridden in all bike lanes and on all streets, multi-use paths and sidewalks.
Rules for Electric Devices
Different rules apply to different types of devices, like e-bikes. Learn more below or on the e-micromobility webpage.

*You may ride e-scooters, e-skateboards and other lightweight electric vehicles on sidewalks adjacent to non-residential streets only if no bike lanes are present. You can not ride on the sidewalk adjacent to streets with a speed limit of 20 mph or less.
Electric bicycles, or e-bikes, are permitted in the City of Boulder. There are different types of e-bikes. Most e-bikes follow the same rules as traditional bicycles and are allowed on sidewalks, multi-use paths, streets and bike lanes. Class 3 e-bikes are not permitted on paths and sidewalks.
The City of Boulder provides shared e-scooters (Lime) and e-bikes (BCycle) through the Shared Micromobility Program, in partnership with the University of Colorado Boulder, Boulder County, the Boulder Chamber, Lime and BCycle. Learn how to use a BCycle e-bike and a Lime e-scooter.
City Trails
City of Boulder Open Space and Mountain Parks (OSMP) allows Class 1 and Class 2 e-bikes on certain trails.
People experiencing disabilities may use Other Power/Driven Mobility Devices (OPDMDs) on OSMP trails, including electric-assisted cycles and handcycles.
County Trails
Boulder County allows e-bikes on most county-managed trails on the plains where regular bikes are permitted.
Open Space and Mountain Parks Trails
- Yield to all other trail users and bicyclists traveling uphill.
- Pass with care and alert others in advance of your approach.
- Control your speed at all times. Safe speeds vary with trail conditions and traffic.
- Practice minimum-impact bicycling: avoid muddy trails, skidding, hard braking and shortcutting. Riding on wet or muddy trails causes serious trail erosion and may result in a temporary trail closure.
Bike Safety

Registering your bike allows law enforcement to more easily contact you if your bicycle is found.

Helpful Tips While Out on a Ride
- Keep right, pass left, and give an audible alert before passing. Always ride with the flow of traffic.
- Bicyclists must yield to pedestrians.
- State law allows riders of low-speed devices, such as bikes and scooters, the option to ride slowly through stop signs without stopping first as long as they yield to pedestrians and other road users who have the right-of-way. Learn how to do a Safety Stop.
- Bikes are required to have a white light on the front and a red light on the back when riding after dusk or before dawn.
Safety Stop
The Safety Stop is a state law that gives people on bicycles and other low-speed mobility devices, such as scooters, the legal option to ride slowly through stop signs without stopping first. Learn how to do a Safety Stop
