Here is an email I got from an actual employee of GT: If the bike frame was manufactured at the Santa Ana CA facility, the first three or four digits of the serial number should be letters abbreviating the model or size of the frame such as 'XL', 'XXL', CR24, or something like that. The next part of the serial number is eight numeric digits. The first four numbers should be a two digit month followed by a two digit year. The last four digits are the serialization digits 0000 to 9999 depending on what number the frame was of the years production. If the frame was made overseas in Taiwan, it gets more complicated. If the number starts with a K, the frame was made. Bicycle Serial Number SearchThe location of the stamping of the serial number on the Series 2 frame was also changed somewhere between 918D and 9143D, there are NO frames we know of before 9143D that are stamped in the same area as the Series 1 Bikes. The serial number is C232336. All it says on the bike is 'MIYaTA' (on the down tube) and Sports Model (on the seat tube), there are also two stickers with red, silver, blue and green stripes (kind of like a rainbow) on the down/seat tubes.

The number will have a production month letter in either the first or second position and a production year number in the other (first or second) position. Examples: J677123 = September, 1976.

There were at least four companies in Taiwan that made the GT lines:,, and included) The first digit would be a letter designating the factory that made the frame. There might also be a second letter digit specifying the factory that assembled the bike, if applicable. The model and year of production was also coded by a letter, so you won't be able to spot a two digit month and two digit year. Huffy Bike Serial Number DecoderBefore I left, I was writing a specification to standardize all of the serial numbers because GT was starting to send most of its US production to other US fabrication shops. The information might also come in handy for deciphering other makes because the factories in Taiwan make bikes for a lot of different companies. The jungle book free download. I am tinkering around with the idea of starting to make my own frames, kind of on a 'one-off' basis. I am also teaching welding at a local community college. By the way, did I tell you that the guy ran GT's in house fabrication for the last ten years (he recently retired) was none other than Gilbert Axt.
