Attached is a picture of my Schwinn Jaguar sport cruiser. The rims, seat, and bars are from a GT mountain bike. The tires are 26 x 1.5. This is one of the few bikes I wish I'd kept. Worked well as a town bike and looked cool. All the changes really helped increase pedaling efficiency and aerodynamics. Because I bought the GT off Craigslist with some damage, the whole project cost $40 + $30 for tires.
