I need your help identifying this bike. . . I picked it up at a garage sale and I’m trying to identify the make and year, and am also trying to come up with an estimated value of the bike. In doing some research it looks like a late 70’s model or possibly a 1980? I attached some pictures and found what I think might be a serial number?? The bike is in almost perfect condition with no rust or damage and all the original stickers are still on the bike and in good shape as well. If you have any knowledge to share it would be greatly appreciated.Thanks!
