I'm part of a start-up effort in an urban neighborhood in Cincinnati. We hope to have our own shop, one day, where we will rebuild and sell bikes, affordably. In the meantime, we have pop-up repair sessions (2 Saturdays/month) planned for the spring/summer, this year.
We did a few of these part of last summer, but didn't charge anything. I am not completely comfortable with that, and would like to ask clients to offer something in exchange. i'd love any ideas about this.
