There was a guy in this area once who had a mobile bike repair business but he combined it with fixing PC problems- one consideration might be other types of businesses which you could combine with mobile bike repair.
I think it could work, you'll have to create a fair bit of the demand yourself. I'm often being asked to do simple jobs on bikes for people I know, there's a whole load of folks who use bikes for transport but have very limited maintenance skills who might use a mobile service but they aren't likely to go looking for it. There's a guy in the local market who is making a good go of repairing bikes- often what we would refer to as BSOs on here. I suspect his customers would not go into the (relatively high-end) cycle shop in town.
