Schwinn Taiwan Serial Number

Schwinn Taiwan Serial Number. 1/3/2021 No Ys in the serial numbers or difference chainstay bridge. The one tell is is Yeti dealt with strictly 7005 aluminum, as it. The Schwinn Web site had a Collectors' Page with info on dating, serial numbers, etc. Mark source has a nice page about codes Schwinn bikes, also some good Date Repair and Restoration tips. If you like Stingrays and Krates I don't.

Thanks to Tom Marshall (T-Mar) from Bikeforums for this information.

The guide is not necessarily comprehensive, as it only represents what has been collected and decrypted. The level of confidence in the decryption is high, unless otherwise stated, though it is dynamic and may not be 100% accurate. Contract manufactured brands are cross-reference to the manufacturer. The nationality of the brand owner ( pre- 1990) is stated in parentheses. Anybody having any further data, insight or corrections can contact me via the forum's private message process. Hopefully, it is self-explanatory with the use of the following legend:

F indicates an alpha character designating the fortnight (i.e. A= weeks 1-2, B=weeks 3-4,….Z = weeks 51-52)

M indicates an alpha character designating the month (i.e. A = January, B= February,… L = December)

Y indicates an alpha character designating the year . The year that corresponds to a particular alpha character can vary significantly. The specific convention will be listed under the manufacturer entry.

mm indicates two numeric characters designating the month (i.e. 01 = January, 02=February,…. 12= December)

y indicates a numeric character designating the last digit of the year (i.e. 1 = 1971 or 1981, 2 = 1972 or 1982, etc.). With such codes, you have to determine the decade based on frame characteristics, components, etc.

yy indicates two numeric characters designating the last two digits of the year (i.e. 81 = 1981, 82= 1082, etc.)

xxxx indicates a numeric characters designating the sequential frame number within a the fortnight, month or year. This number string is typically four to six characters in length but can vary.

MARUISHI (Japan): Unknown, but format appears to be Y?xxxxx based o n very limited sample size. Year indicators appear to be A =1971,1981,etc, , B = 1972, 1982, etc. Second alpha character appears to be either fortnight or month indicator. Easily confused with Tsunoda.

MATSURI (?): See Nissan.

MATSU****A/NATIONAL (Japan): yMxxxxx

See also U(1) for some late 1980s contract manufactured models.

MITZUTANI (Japan): Insufficient data.

MONGOOSE (USA): Insufficient data.

MOTIONCRAFT (?): See Miki.

NIKO (USA); Niko was the private label brand of retail and mail order store Bikecology. Owner, Alan Goldsmith, also worked for Western States Imports (Centurion) . While I have no Niko serial numbers, 1980s Niko models do strongly resemble Centurion and owners are suggested to check the serial number formats of Centurion contractors.

NISHIKI (USA): See Araya, Dodsun, Fairly, Giant, Katakura, Kawamura, S(4)

NASHBAR (USA): see Maruishi

NORCO (Canada): See Dodsun, Kawamura, Miki, Yamaguchi.

NOVARA (USA): See Fairly, N(1).

N(1) (Japan): NyFxxxx Manufacturer unknown. Some members believe that the ‘N' prefix designates National but given that Panasonic and the Japanese manufactured Schwinns that came from Matsu****a/National do not use this format, it seems unlikely. There is evidence suggesting Tano, the major supplier to WSI/Centurion, though the format is different from that use in the 1970s.

BF member Hummer believes that the 3rd character is a month indicator with the 12 months being represented by A, B, D, E, G, H, K, L, M, N, P & S.

RENSHO (Japan): Insufficient data.

REX/REX II (Japan): Insufficient data. AKA Criterium Rex, the head badges on these bicycles denote Araya manufacture. They appear to be 1970s forerunners of the Araya branded bicycles of the early 1980s, but with a different serial number format. The format is similar to Bridgestone & Miyata, though frame characteristics, notably the distinctive seat stay caps, are different.

SENATOR (?): Insufficient data.

SHIMANO (Japan): Shimano manufactured complete bicycles from September 1950 to May 1954 but these are extremely rare. After that, Shimano would commission frames to build up and use for displays at bicycle shows but these were generally high end models. Most Shimano bicycles that surface have been rebranded by their owners. Consequently, there is too much variation in serial number formats to list.

TANO (Japan): not yet decoded

TEAM CHANCE (Canada): See Hodaka

TSUNODA (Japan): Unknown, but format appears to be YFxxxxx though correlation for Y has not been determined. Some members believe that Tsunoda was only a trading company and not a manufacturer but Lotus bicycles often have labels stating 'Made by Tsunoda Japan' and similar statements can be found in Lotus literature. Easily confused with Maruishi format.

U(1) (?): Uymmxxxxx Manufacturer unknown. These codes start appearing on Centurion and Diamond back models in the very late 1980s. It is known that China Bicycle Company started supplying entry level models to Western State Imports at this time, just before acquiring WSI in late 1989 and this would appear to be the logical manufacturer but bicycles with this S/N format have been reported with Made in Taiwan labels and CBC was located in China.

Y(1) (Japan):Yyy mmxxxxx Manufacturer unknown but circumstantial evidence indicates it may be the pre-1980 Yamaguchi format.

Y(2) (Japan): YLyMxxxx Manufacturer unknown but may be for Yamaguchi aluminum frames as these typcially surface on brands of aluminum frames who used Yamaguchi as a source for their aluminum frames.

YAMAGUCHI (Japan): YyMxxxx. To date there have 11 letter codes reported for the 3rd character (A though N, shipping D, I & J), so it is believed to be a month code. Of the 3 missing codes, D is probably the legitimate code.

There has been some speculation whether Yamaguchi is the manufacturer for this format but samples have been reported with Yamaguchi labels.
