That is a ridiculous! I manage a shop near where I live and most of the money coming in is bike sales throughout the company. Repairs are a big part but will likely not overshadow our bike and accessory/part sales. Certainly during some times we get more repairs in but we are still generally doing better through sales rather than service.

I am sure there are some shops out there that rely on bike repair but many of the ones I know seem to do a bang up business sales wise rather than repair wise. However there are plenty of people who have mechanical knowledge who still would rather leave it up to the people who do this for a living rather than just as a hobby.
