Up for sale in San Juan Capistrano is a super nice Schwinn Twinn tandem bicycle from 1967-69 which has been mothballed for 40+ years. The owner claims the bike is completely original down to the original tires and handle grips. The starting bid is $300 with a $575 “buy it now”.
From the owner:
1967-69 Schwinn Deluxe Twinn stored in the attic for 40+ years. The bike is green and has a collapsible child seat, and is completely original down to the original tires and handle grips. The shiny surface has a light covering of surface rust. The painted surfaces have not been cleaned to prevent damage to the decals. The generator head light works, the child seat is collapsible, the pedals spin & the chains work and have been oiled and the brakes appear to be in good condition. The serial number is DE22439. I am the second owner and traded for the bike at least 40 years ago. This would be an ideal bike for restoration.
