However, the real test would be with real data.Are you trying to breakout this data on bikes you own, bikes you want to purchase, or are you doing this for all of the bikes manufactured by these two?Do you have a complete list of those you want to parse out?If so, why not post it as an attachment to a Reply, so that I can get a better feel for the complete picture?HTHLee Edited Septemby Guest. (Go online to for a list of serial numbers between 19.) Those bikes produced between 19 typically start with a letter representing the month it was produced (A=January, B=February, and so on) followed by a digit representing the year (9=1959, 0=1960, 1=1961, 2=1962, 3=1963, 4=1964).Read the serial numbers of bikes produced between 19.

Those Schwinn bikes produced before 1959 have no real system to numbering but the serials typically contain six or seven numbers or letters.

Those produced after these dates will usually have a serial number stamped on the bottom bracket shell (the rear axle hanger holding the wheel in place).Identify Schwinns produced before 1948 by looking for either of these serial numbers: B12818 or Z12993.Interpret the serial numbers of bikes produced between 19. Look for the serial number on the lower head tube (right above the wheel on the front of the bike) for Schwinns produced between 19.
