Bike Events

We’ve compiled a listing of Bay Area bike events for the year.  Find out more about organized rides, more casual group rides, bicycle club rides, repair lessons, bike parties and even bicycle bingo.

Does your office need a bike rack?

Thanks to Bay Area Air Quality Management District grants and local county sales tax funds, we can provide bike lockers and racks for business sites, retail centers, schools, colleges, and public buildings to support and encourage bicycle use. Contact us today for more information about this program.
