What does a bicycle serial number mean?

The bike serial number of your bicycle is an important identifier for product management. There’s no single format as manufacturers and factories decide arbitrarily, but there are stamps on frames to indicate which type it may be- domestic or city cycling style; also an engraved number near the top tube in front before you start riding that will tell everyone just what they need at any given time!

Each manufacturer has their own identification system. The serial number (and sometimes letters) can include digits that represent the month, year or model code – as sequential production numbers or variants of any of these. If you’re lucky, the serial number can give you the year included in the number in an obvious format. 

Schwinn, for example, has quite a simple system with only a few variants that include the date of manufacture. There is also an easy ‘look up’ tool for Schwinn at Bike History.

The best way to read a bicycle serial number is to search the web for “[brand name] bike serial number decoder”.
