My son bought this in a yard sale and we'd love to know what it is and how old it is, as well as what it might be worth. He plans to have fun with it, clean it up and ride it with his friends, but it would be good to know if he paid a fair price out of his allowance money!
It's a Schwinn tandem bike. The seats look old-fashioned but are in good condition. Some of the metal parts are rusty but the chain appears to be just dirty. It works fine. Foot brakes, single speed. Original color appears to have been green and it was painted blue on top - there's a little blue paint on the silver "Schwinn" plaque on the stem. Any help much appreciated!
