There have been three different incarnations of Schwinn. The first was owned by the Schwinn family from the beginning until it went bankrupt in 1992. Most of their bikes were made in Chicago until 1982, when they shut the Chicago plants down. They subcontracted with Murray (Lawrenceville TN) for a couple of years, then most of their production was taken over by Giant in Taiwan, although they still produced small numbers of high end models in the U.S. until the end. The Scott Sports Group bought Schwinn after the first bankruptcy and continued to import the bulk of their bikes although they also produced some high end models in the U.S.
Schwinn went bankrupt a second time in 2001 when it was taken over by Pacific Cycle/Dorel, and as far as I know, all of their bikes have been made in Taiwan or China, probably under contract by various manufacturers. Most of the members on this forum are mainly interested in the Chicago-built models. Some of the later models are interesting but are not old enough for nostalgia and are priced in line with other used bikes. Most of the rest are considered "Wal-Mart" bikes (Always the low price, always!) and attract zero interest. Like
