Maybe it's about gas prices. Maybe it's about love handles. Maybe it's the idea of flying down Market with the wind in your hair. Whatever the excuse, it's time to dust off the Huffy and ride. To get that old horse running, hit the Bike Kitchen, a cooperative repair shop with a full tool set and volunteer mechanics. They won't fix it for you, they'll teach you to fix it yourself. Patrons are encouraged (not required) to buy memberships in exchange for using the tools and services, and the money is funneled back into the shop and its community programs. In addition to fixing up clunkers, the Bike Kitchen will also help patrons build a two-wheeler from scratch, using donated parts. People can even earn the bike they build by volunteering. For the thrifty biker, it's a dream come true. There's no phone, but if you want to cruise over to check it out yourself, mind the hours: Tuesdays between 6 and 8 p.m., Thursdays from 4 p.m. to sunset, and Saturdays between 11 a.m. and 4 p.m.
