Here's a great documentary-style Streetfilm about the Recycle-a-Bicycle program from Elizabeth Press, who writes:
Recycle-A-Bicycle takes donated bicycles, repairs them and reintroduces them to the community through earn-a-bike programs in schools and sales from their non-profit retail locations. Although their work mainly focuses on environmental education and job training programs for New York City youth, they also host repair classes for people of all ages. Every Tuesday evening after the shop closes, Susan Lindell teaches bike mechanics 101 to women.
