VéloCity Bicycle Cooperative
2111 Mount Vernon Ave.

The friendly spirit of the neighborhood is in high gear at VéloCity, which takes donated bikes, then rehabs and sells them and their parts for a good price. You fix your own bike, with help from experienced volunteers, and use the shop’s tools and supplies for just $10 an hour. “Everyone helps out everyone here,” said volunteer Joe Brown. “I live near Skyline [neighborhood] and am over here all the time. I wish we had something like this.”
