About Us

The Bike Cave is a volunteer-run no-cost bike shop located in the basement of the Dorothy Day House.  We welcome all skill levels and strive to provide a safe space for people to repair or build a bicycle.  There is no monetary charge for any bikes or bike parts.  New bicycle enthusiasts can expect to get their hands dirty while working alongside one of our volunteer mechanics. Veteran bikers can come to access the shop tools.  While bikes do not cost money we do expect everyone to participate in the maintenance of their bike and/or help with a volunteer project around the shop.  All bike adoptions typically require about six hours of work, plan to spend at least two days at the shop if you are looking to get a bike. 


We are always seeking individuals who can volunteer their time and energy to this project. The Bike Cave is a great place to practice or grow your bike mechanic skills by giving new life to old bikes. You can also contribute to the Bike Cave by donating bikes, bike parts, tools or cash to buy supplies for the shop. Please only bring bike donations during our open hours.
