Cool thread. When I was an undergrad at UCLA, one of the law students started a small used bike shop in Santa Monica, and advertised me as "house bike freak and mechanic." The enterprise was relatively short-lived, but it was fun while it lasted, and I did enjoy meeting local residents who appreciated our prices and our hours (early mornings and late afternoons, so that people could drop off bikes for repair before work and pick them up after. I wish you the best with your new shop, as I see a need for this sort of business.
