Gary Fisher Serial Number Decoder

Here are over 130 bicycle catalogs and bike brochures for Trek, Gary Fisher, Klein, and Greg Lemond. Trek provided these scanned and digital technical documents to its dealers. Over time, Trek expanded its domain by purchasing other bicycle manufacturers. These include: Gary Fisher Bicycles, Klein, and Greg LeMond Bicycles. Welcome to Rickenbacker's serial number decoder page. Rickenbacker serial numbers have been issued in a number of formats. To the right and below, you will find some images that will hopefully help you to locate the complete serial number on your instrument. Please be aware that some instruments manufactured in the late '50s cannot be.

All bikes1all have unique serial numbers.

Finding a bicycle serial number

Most bicycles have their serial number engraved beneath their bottom bracket, but sometimes serial numbers are found in other places. Here are some examples of where and what to look for:

  • The bottom bracket (where serial numbers are typically located) is circled.

  • A serial number on the underside of a bottom bracket.

  • Another serial number beneath the bottom bracket, aligned parallel to the frame.

  • Rad Power bikes have their serial number on the head tube. This is on the front of the bike.

  • Some Schwinn bicycles also have the unique identifying number (their serial number) on the head tube.

  • A serial number located on a rear dropout. Some BMX bikes and a few Schwinn bicycles place the serial on the rear dropout. On older Schwinns there are numbers stamped on both the drive side and non-drive side rear dropouts; the one on the non-drive side dropout is the serial number.

  • Some bikes have multiple serial numbers.2When adding a bike to the Index, it's best to enter all the groups of numbers and letters separated by spaces.

Hopefully you can find the serial number on the bicycle you're looking at - email contact@bikeindex.org if you're having trouble.

Searching serials on Bike Index

Finding bicycles by serial number on Bike Index is a critical part of our functionality. When searching for a serial number, use our serial search bar - it's the second bar on our search form.

We've done a few things to make it more likely that you'll find the bike you're looking for.

  • Certain numbers and letters are difficult or impossible to distinguish between (e.g. 0 and O, S and 5). We treat all these numbers the same way - a search for 005LLL will match a bike with the serial OOS111.
  • We split bike serials up by spaces and store each separately. If you see multiple numbers on a bicycle - such as in the photo of the Look bike above - try searching for just one of the numbers at a time. Searching for eitherM4106I9CA1 or 200910427-2A will find the bike.
  • We do close serial matching - bikes with serial numbers that are close to the serial you entered are shown below the matching results under the heading 'Serial Numbers Close to...' - given a search of a serial number with a couple numbers/letters that are different or missing.
  • We do not currently do partial serial searches. If you search for 1234, you will only find bikes with serial numbers of 1234 and serials close to that - not a bike with serial number of 12345689.
  1. Okay, fine, so maybe there are a few bikes without serial numbers, but this is rare and typical only on hand made bikes or really old bicycles.↩
  2. In this picture 200910427-2A is a manufacturer number and not a serial number. However, to make bikes as easy as possible to find, feel free to enter all numbers you encounter.↩

Enter your Schwinn serial number in the box and click 'find' to see what date and year your Schwinn bike was manufactured.


This tool searches a database of Schwinn serial numbers and if it finds a match to your serial number then it will display the information available for your bike.

Notes: This tool works for Schwinn bikes from 1948 to 1982. All serial number records before 1948 were lost in a factory fire.


Serial Number Location

The serial number can typically be found in one of three places on a Schwinn made bicycle.

  • The headtube
  • The rear dropout
  • Underneath the bottom bracket shell

Note: The serial number will always be found on the actual frame of the bike. In other words, it will not be found on a bike component (like a handlebar or a pedal).

Example Numbers

Schwinn serial numbers commonly have one of three formats:

  • All numbers
  • One letter followed by numbers
  • Two letters followed by numbers

Here are some example numbers: 0465228 - F106791 - EB37868

What a serial number can tell you

Gary Fisher Serial Number Database

The serial number on a Schwinn frame will tell you the date that frame was manufactured. It will not identify the model of the bike, only the year the frame itself was manufactured.
