I struggle with the thought of fixing up department store Huffy and Murray 10 speeds ('road' bikes) from the 70's and 80's. They always need tires and tubes, which means $20-30 and then another $5-10 for cables and brake shoes. That would put things at $40 for the parts, so to make it even worth the trouble, I would need to charge $75-80 for the bike. That seems like too much for that quality of a bike, even if it has been completely serviced.

Do others bother with these kinds of bikes and if so, what do you list and sell them for? These seem to be the only kind of bikes I find for free.
