Diamondback Bmx Serial Numbers

All bikes1all have unique serial numbers.

Finding a bicycle serial number

Hey guys, I just got this Diamondback off of Craigslist for 50 bucks and wanted to know if anyone could help me find out what model and year it is. Was wondering if there is any DB pros on here. My serial starts with VM. The bike appears to a 1979 pro with the d package (blue). Any help is appreciated thanx.

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:

Diamondback Serial Number Guide

  • 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.

  • Some Schwinn bicycles have the unique identifying number (their serial number) on the head tube. This is on the front of the bike.

  • 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.

NumbersDiamondback serial number guide

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.

Serial Numbers Microsoft

  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, we'd love it if you entered all numbers you encounter.↩
