No. Sears bikes were junk, it's not even worth the gas to take the bike to a recycler and getting the cash from it!
There were certain 3 speed bikes that were sort of decent, the Schwinn Speedster and Racer, the Raleigh Superbe, Hecules, and a few others. But I'm not into the 3 speeds that much to list more great models of those, but the Sears was a piece of junk as were other retail store branded bikes back then...kind of like it is today.
