A bike serial number is a number on the frame of the bicycle (near the pedals of your bike) that indicates its retail production year. The serial number is usually followed by a letter or two which indicates the manufacturer, model, or country of origin.

Background of bike serial number


Serial numbers are important for bicycles because they can help law enforcement track down stolen bikes or identify when a bicycle has been reported stolen. The serial number is also used to track the history of a bike, which can be helpful in determining whether a bike is worth repairing or selling.


Bicycles are typically manufactured with unique serial numbers. The serial number is usually located on a plate attached to the frame of the bike, but it can also be found on the bottom bracket, seat post, head tube, or fork. The serial number is usually composed of letters and numbers, but some bikes may have just one letter or number.


Most serial numbers are printed in black or blue ink and are about 1 inch wide and 8 inches long. The first letters of the serial number correspond to the manufacturing batch, and the remaining letters and numbers correspond to the bike’s sequential order within that batch.


Bicycles that have been modified in any way (such as adding accessories or changing their frames) may have different serial numbers than those that were originally manufactured.
