$50 as is, if you spend another $50 to $75 per bike replacing all the consumables, bearings, grease, cables, housings, tires, and about 4 to 6 hours of time, you could get $75 for one. Find any problems and the $75 per bike estimate is too low. This assumes you have the time/tools/space/skill to do the work yourself. Pay a shop for all that work and its more like $200 per bike to fix them up.

Low end bikes from the 1970s are not worth restoring unless they have sentimental value (belonged to a parent, was your old college bike, etc.). Then they are worth refurbishing.

You are talking 45 year old bikes there. Grease gets old, really old. Brake pads get rock hard, tires dry rot, cables rust, etc. It turns out for projects, I find it better to aim higher. It costs the same $75 to refurbish a bike that might be worth $300 when you are done, and take the same 4 hours. In the 1970s, nice bikes were far less common. It was the bike boom, where anything with two wheels was easy to sell. By the 1980s, the boom was over and brands had to either upgrade their products a lot, or die.


No, the wheels are not 700c. When you see stem shifters, cottered crank, stamped drop outs, claw RD hanger, etc., you will have 27 inch wheels. Heck, even the American Eagle Semi Pro from that era had 27 inch wheels (several models up). If you want 700c wheels, you should look at mid to upper level road bikes from the 1980s.
