Travel by Bike

On this page

Before you ride on campus remember to:

  • Buy a helmet and wear it correctly.
  • Register your bike.
  • Install a light so you can safely and legally ride after dark.
  • Use a U-lock to help deter theft.
  • Be aware and respectful of pedestrians, skateboarders, and other cyclists.
  • Not lock your bike to anything other than a bicycle rack. Bicycles locked to trees, ADA hand railings, garbage cans, etc. may be impounded. Please review page 20 of the Bicycle Regulations.
  • Check out Colorado bicycling laws.

Bicycle Registration

Register your bike online!

  • Bike registration is free of charge and mandatory on campus.
  • Many homeowners and renters insurance policies will cover your bike if it’s stolen and has been registered.
  • Call 303-735-BIKE (2453) for registration information.

If Your Bike is Missing

  • If you are certain your bike was stolen, report the theft to CUPD at 303-492-6666 or file an online report.
  • If you aren’t sure, fill out the Missing Bike Inquiry Form to find out if your bike was impounded.

Impounded bikes

If a bike appears to be abandoned, was locked to something other than a bike rack, impedes disability access or any kind of traffic flow, your bike may be impounded. Registered impounded bikes are held for 90 days, and non-registered impounded bikes for 60 days. The easiest way to claim a lost, stolen or impounded bike is through registration records. Register your bike at either of our two bike stations. (Near the UMC, and Folsom Station near Engineering.)

If You Need Your Bike Lock Cut

  • If you lose the key to your bike lock and you've registered your bike with CU-Boulder, submit a bike lock cut request form.
  • If your bike isn't registered through CU-Boulder, please contact a local locksmith.

Theft Prevention

University campuses can be a target for thieves. Following a few common sense guidelines can help keep your bike safe.

  • Register your bike; it's a theft deterrent and the only way to get a stolen bike back to you.
  • Protect your investment with a quality U-lock.
  • Always lock your bike, even if you’re only gone for a minute.
  • Consider getting a “beater” bike for campus use. A good thief can break through any lock given enough time. Having a bike just for commuting can save you the heartbreak and headache of losing a good bike.

Bike Program

The Bike Program is your one-stop shop for all things related to biking at CU. Operated by Parking & Transportation Services and the Environmental Center, the CU Bike Stations offer mechanic assistance, Buff Bike 2-day free rentals (free to faculty, staff and students!), and semester rentals.

Bike Stations:

Bike stations on campus offers numerous ways to help keep our campus cyclists in the saddle and enjoying the campus and Boulder's great environment. We value the bicycle as an effective means of commute and recreation, improving its users' health, mobility and economic vitality.


  • The bike station staff is here to help you with basic bicycle repairs. We are not a full service bike shop and therefore are limited by time, ability, staffing, and supplies. 
  • Our hope is that by teaching you how to keep your bike in working order we will help foster a strong campus cycling community.

UMC Bike Station: located at the Northwest corner of the UMC by Hellems Arts and Sciences. (For open hours please check the CU Environmental Center website.)

Folsom Bike Station: located at the southwest corner of the Engineering Center. (For open hours please check the CU Environmental Center website.)

Electric Bicycles on Campus

The Boulder City Council has adopted an ordinance to authorize a pilot project allowing electric-assist bicycles (e-bikes) on paved multi-use paths, not including paths on Open Space and Mountain Parks lands. On campus we have temporarily adjusted the University of Colorado at Boulder Parking and Traffic Regulations to coincide with the pilot ordinance. This means that on campus e-bikes, as defined in Section I.C.3 of the regulations, are “permitted to be operated on designated multi-use paths on, through, and around the CU Boulder Campus, unless otherwise indicated. In addition, e-bikes may be operated anyplace that a regular bicycle may be operated, EXCEPT that they may only use the electric assist while operated on motor-vehicle facilities (including bike lanes) and on designated multi-use paths. An e-bike operated on any other campus sidewalk may only do so exclusively under human power.” Check out the amended Regulations on the Parking and Transportation Services website, and the City’s pilot ordinance located on the City of Boulder website.
