Locate Your Bike’s Serial Number

The diagram below shows the five most common serial number locations. 

Most bicycle serial numbers are located under the bottom bracket where the two pedal cranks come together (1). Simply turn your bike upside down and record the number. Check for the serial number on the headset at the front of the bike (2) or the rear stays (3). 

Can’t find anything? Describe the bike the best you can when registering and provide a picture to prove ownership.
