Giant Bike Serial Number Lookup

Serial

If the bike frame was manufactured at the Santa Ana CA facility, the first three or four digits of the serial number should be letters abbreviating the model or size of the frame such as 'XL', 'XXL', CR24, or something like that. The next part of the serial number is eight numeric digits. Bicycle Database; Years Selected Year: 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008.

Your best bet is to figure out the manufacture of the frame, and see if they have a lookup for it. However, all of this is generally irrelevant, as who originally made a bike doesn't have any real bearing on its. I have a Giant Boulder SE mountain bike. I think I have found the serial number, on a white sticker beneath the lower tube, right by the cranks. Sorry but it doesn't look like a serial number I know it's a bit late now but I tend to register with themanufaturer, make note of the number and take a photoof the serial number on my phone, back it up and keep it on my phone, as having a photo dated a year ago of the serial number could well help with proof of ownership is stoped by the law.

Bike

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.↩

Schwinn Bike Dating After 1965,
Schwinn serial number sequences, while appearing to be
confusing on first sight, follow several general rules. If the
first letter is a 'A' through 'M' it refers to production month
('A' = January, 'B' = February, etc.).
The letters 'I' and 'O' are not used, to avoid mistaking
them for numbers. If there is only one letter in the first two
positions, the first number or two numbers refer to production
year. Date Codes occupy the first two, three or four positions
in a serial number.
Mass produced Schwinn bikes have been followed
by a production month letter and several numbers, the
first two signifying year of production (81 = 1981, etc.).
Example: D72130 = April 1972. LeTour (and Super LeTour)
numbers (1978-80 and 1982 on) include the letter 'S'
with year of production (8 = 1978, 0 = 1980). Example:
SC94653 = March, 1979. Sting 20' racing bikes have a
production month letter 'T' signifying that it is a tri-oval
frame (with three frame tube ends ovalized). Example:
F1T20404 = June, 1981.
Imported Schwinn serial sequences depend upon country
of origin. Bicycles from Japan have a production month
letter in either the first or second position and a production
year number in the other (first or second) position. Examples:
J677123 = September, 1976. Taiwanese imports have a
separate date code number on the right rear fork end that
includes the letter 'G' followed by a two-digit month code
(01 = January etc.) and two more digits for the production
year (80 = 1980 etc.). Example: G04813 = April 1981.
Also Note that if your bike is after year 2001 the
Schwinn/Questor bankruptcy, It has been found
that ( Pacifc Cycle ) bikes do not use this dating.
