Feb 09, 2014 Since there are many misconceptions about the Schwinn serial numbers I want to devote this. Then there are the Taiwan Schwinn bikes that vary in.

Later Schwinn serial numbers / years made Bicycles from Japan made in the 70’s 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, 6J77123 = September, 1976. During the 1980s, Greenville used the old letter-digit (e.g. F8 = June 1988 )system which Chicago abandoned in 1965, when it changed to the two-letter system.

Some Taiwanese (built by Giant) Schwinns have a date code (on the right rear axle hanger or on the bottom bracket shell) in the format ' Gmmyy'. The letter 'G' followed by a two-digit month code (01 = January etc.) and two more digits for the production year (81 = 1981 etc.). An example would be 'G0181' and equates to 'Giant, January, 1981'. On bikes made after 1982: You can find a 4 digit serial number lightly stamped onto the headbadge. The first three digits are the numerical day of the year, and the last digit is the last digit of the year. EXAMPLE: 3654 is 12/31/84 or 94?

You determine decade. Generally the 4 digits on the headbadge breakdown as follows: First 3 are the date of build 1 thru 365, the 4th (last digit) is the last number in the year. So '0' probably stands for 1990.

If you are not sure which decade the bike is from, check the parts and graphics on the bike to the pictures in the catalog pages. Most Paramount serial numbers would start with a letter and then 2 to 5 numbers. My 1974 for example is A74149 or the 149th frame from January (A) 1974 (74).

I believe there was a Schwinn model named 'World,' so that very well might be it, a Schwinn World. Look on the headbadge for four small stamped numbers, first three will represent the numerical day of the year, the last will represent the last number of the year the bike was assembled. Example: 1508 would mean 150th day of '88. Certainly looks to be an '80's bike, and the beginning of the serial # 'CE8' may indicate 1988, although as we've found lately, there seems to be a lot of unknowns with these '80's Schwinns. Also, I'd guess it's from either Japan or China, as the serial numbers from the American made models from this era seem to begin with 'S' and the Giant-built models (from Taiwan) seem to begin with 'G.'

Is there labeling that indicates where it was made? I'll check and get back to you.

For dating purposes i usually use the head badge and components so I don't have the serial numbers logged. Thanks.I'm thinking 'G' for Giant, of course. That would cover the Taiwan-built Schwinns. Maybe the 'S' serials from the '80's are indeed from Mississippi, and a 'C' serial from the '80's, like novelite's, would indicate a Chinese-built Schwinn from China Bicycles (Schwinn's source in China, according to Scooper in your recent post about Taiwan-built Schwinns).

That wouldn't cover the Japanese-built Schwinns, but still.could it be that simple? Hey crazyb, do you know if your Schwinns that indicate they're made in Taiwan have serial numbers starting with 'G'? I've heard this from time to time here, and I've got a Taiwan-built Schwinn High Sierra mtb with a 'G' serial number- Ok, here goes; 1984 World Sport sn G0584 1983World Sport mixte sn G1183 1981 World Tourist sn G0181 all serial #s on rt dropout.

1989 World made in China, sn on bottom bracket shell, SD921539 A note to the op. If the sn is on the rt dropout and has a G in it, it was probably made in Taiwan.

If you cant find a decal on the seat tube. Schwinn seemed to be very good about labeling country of origin on their 80's bikes. No serial on either dropout and no decal on seat tube, though I think I can see where it used to be. And, upon further inspection, the serial on the bottom of the crank case is GE800947, not CE800947. From what I'm hearing, I'm going to assume that this frame is a 88 World Schwinn made in Taiwan by Giant.

I think that's a fairly logicial conclusion (if there is such a thing as logic regarding these '80's Schwinn serial numbers!). My '89 High Sierra mtb has a decal that says 'made in Taiwan,' and has a serial # starting with 'G,' stamped on the bottom bracket, and has eight characters in the serial, as yours does. Scooper (who knows a lot more about this stuff than I do) has said recently that he doesn't know of any other 'made in Taiwan' sources for Schwinn other than Giant, and I've seen several sources say the serials starting with 'G' are likely Giant-built Schwinns. Hope all this helps, and thanks for your patience as I got off topic a time or two in trying to shed some light on the origins of these crazy '80's Schwinns.They're nice bikes, IMHO. Welcome to C&V. Sometime resurrecting an old thread is not the best way to have your questions answered.

Try starting a new thread from the main page by clicking the appropriate button at the top of the page. Use a title something like 'Help me date my vintage Schwinn Cruiser.'

Post pictures of your bike. Take a full shot from the chain side, the decals, headbadge, and the serial number. Closeups of any other parts you think are unique. Generally, on Chicago built Schwinns of the '70s, the letter 'U' would not be used in a serial number.

The first letter designates the month the frame was built. In this case 'J' equates to August ('I' was skipped). The second letter designated the year.

1979 was assigned the letter 'Q' so 'U' would equate to 1983. Here's a link to catalog pages associated with that year.

No cruisers are there for you to ID your bike. Looking back in the catalog shows the last entry to be 1982. Schwinn was in a big transition during this time and they probably continued to make the same model into 1983. Pictured is the '82 catalog page.

Guys, the 'GMMYY' number stamped in the right rear dropout does indicate that the bike was built by Giant (Taiwan), but it's a date code, not a serial number. It indicates the month and year the frame was made, while the numbers stamped in the head badge indicate the assembly date of the bike. In this case, it's a. Besides Giant, Schwinn also used A-Pro in Taiwan for some models, notably the Series 2, Series 20, Series 3, and Series 30 Paramounts in the early 90s (the Series 5 and Series 7 were built in Japan by National/Panasonic). Been looking all over the internet. Some site's end at 1982 and lead you to believe that my Schwinn Cruiser is a 1983. Another site shows that it was built from 1975 to 1979.

Would like to find out what year my. Serial number on front neck is JU515529. Any info would be appreciated.

JUxxxxxx indicates a September 1983 frame. There should also be a 4-digit number stamped in the headbadge (next to the letter 'i' in Schwinn) that will indicate the day the bike was built, what is that number? Here is the '83 Cruiser catalog page.
