This page provides year by year images and info quoted from Schwinn catalogs for the World from 1950 to 1988.

1950

Schwinn serial numbers may be found in several different places on the bike. Most bikes from the 1960s are stamped with the serial number next to the spot where the rear wheel axle connects with the frame. Starting in the 1970s, many bikes were manufactured with the serial number on the Schwinn seal, located somewhere on the bike's frame.

For features, design and workmanship, these bicycles outrank any in their class.
