Locating your bike’s serial number


Most bicycle serial numbers are located under the bottom bracket where the two pedal cranks meet. Simply turn your bike upside down and record the number. If there is no serial number there then check places like the headset at the front of the bike or the rear stays. The diagram indicates the five most common serial number locations. The best chance at recovering a stolen bicycle is having a registered serial number. These numbers are used by police across the nation. You need the manufacturer’s serial number to register your bicycle.

#2 headset
#3 rear stays
#4 seat downtube next to crank
#5 top of crank

Here is an example of what the serial number will look like.
