Davis Bike Church
The University of California - Davis has a bike church complete with its own ministers. It's part of the Sustainable Research Area on campus. The purpose is to promote various forms of human-powered transportation including biking.
It offers new and used bikes, parts, and accessories as well as tools and advice on how to fix bikes. The non-profit is operated by volunteers. All donations go to providing the community with more tools and a better workspace.
If you have a bike, bike parts or tools you are no longer using, please consider donating them to The Bike Church: bikeministry at ucdavis dot edu.
