Charles Haine has been a bicycle mechanic for over a decade. He learned to fix bikes at a bicycle co-operative at Oberlin College, followed by stints at several bicycle shops in his hometown of Washington, DC, including Blazing Saddles and Citybikes, and time at both the Bike Spot and Bikecology in Los Angeles. He is currently the chairman of the Bicycle Kitchen, a non-profit bicycle education space in Los Angeles, California, where he has also been a volunteer for 7 years. He has taught beginning and advanced bicycle mechanics to countless numbers of both the general public and also other volunteers at the Bicycle Kitchen to help them hone their mechanic skills and better serve the community. In his spare time he gets into arguments about how to properly address brake squeak. Visit him online at http://www.bicyclekitchen.com.
