Spokesman Bicycles, Santa Cruz

Spokesman Bicycles' mechanics obviously ride their bikes to work, but that's not the only thing they do to reduce their impact on the environment. They also donate used tubes and tires to Totally Tubular Bags, use a biodegradable fluid in their parts cleaning machine, and ride whales to work only on special occasions.

But they didn't get into biking just to help the environment—they love everything about the sport, and many of them have been seriously cycling and fixing up bikes since the '70s. At their shop, the mechanics build road and mountain bikes, as well as work with fitters who adjust each bike to fit the needs of the rider. To keep clients safe and happy, they pass on their expertise to riders during free maintenance classes every month.
