Good people, doing good things to get more people on bikes. They offer FREE assisted bicycle repair. You're not bringing a bike there to get fixed, you're bring it there to learn how to fix it!
The #1 thing that keeps people from riding a bike if fear of a flat tire. So go learn how to fix flats, adjust brakes, set seat height, re-build a bottom bracket... the choice is yours!
As mentioned above, the service is all free. But the rent isn't, so donations are accepted. Wheels, frames, cables, even cash. I'm told the volunteers like OH- as well, so you can see how that works out.
