Finding Your Bike’s Serial Number: Importance and More

Your one stop guide to know it all about Bike Serial Numbers. Let’s explore what bike serial numbers are and why are they so important.

Do you know that a common myth about bike serial numbers is that they are not important? And I kid you not, it originated because many people believe that bicycles are not precious commodities. But guess what? The serial number is the most important feature of your bike, regardless of the components. Yet, a study conducted at the University of California, Berkeley showed that:

“Only 17% of the bike owners know about their bike’s serial number”

On the flip side, If your bike gets stolen, your serial number will play an important role in retrieving it. Believe it or not, the recovery rate of a stolen bicycle is only 2%, according to the National Insurance Crime Bureau. Now, not knowing your bike’s serial number further decreases these chances!

What Are Bike Serial Numbers?

Bike Serial Numbers are a series of digits between 6 to 10 digits. They are also called bike frame numbers.

I can’t emphasize this enough but your bike serial numbers are very Important. You will have to rely on them a lot in case they go missing or get stolen. I have seen many people suggest safe-keep pictures with the bike in case of a mishap. Pictures won’t be enough. The authorities use the bike’s serial number to track it down. In The United Kingdom, all you have to do is register your bike on BikeRegister.

This way the police will already have your serial number when something happens. But in The USA, you have to know the bike’s serial number. There is no National Database for a bike serial number here. There are only a few police departments that collect these numbers, so it is better to know it yourself.

Examples of a Bike Serial Number: 

  • MU 6102-1:1992.
  • M4106I9CA1
  • M3A00055

Note: If the serial numbers exceed the 6-10 limit, then it might be the manufacturer’s number.

Let’s take a look at some of the bike manufacturers and their product serial numbers:

  • Trek: Mostly Starts With WTU
  • Specialized: Specialized Uses These Prefixes: WSBC, WUD, STT, and STE
  • Cannondale: Will Have 7 Digits Mostly
  • Giant: Mostly Starts With GU
