- The ordinal dating was adopted for Schwinn’s domestic production in 1976.
8. What Does an “X” in the Month Position of a Japanese-Built Schwinn Serial Number Indicate?
An “X” in the month position of a Japanese-built Schwinn serial number indicates December, with the model year of the remainder of the production for that model year, providing a specific marker for bikes produced at the end of the year. This is a unique identifier that helps in narrowing down the production period.
- An “X” in the month position of the frame serial number was used to keep the physical year of production.
- Example: X9 = December of 1979, with the model year of the remainder of the production for that model being 1980.
9. How Do I Decode the Date Code on Taiwanese-Built (Giant) Schwinn Bikes?
Taiwanese-built Schwinn bikes manufactured by Giant have a date code in the format “Gmmyy” on the right rear axle hanger or bottom bracket shell, where “G” is followed by a two-digit month code and two digits for the production year, offering a straightforward method to determine the bike’s manufacturing date. This code is a reliable way to identify the age of your Taiwanese-built Schwinn.
Format:
- G: Indicates that the bike was built by Giant.
