Apr 11, 2005 Just picked up a vintage Gitane 10 spd road bike.Reynolds 531 cromally frame, competition drive train (52/39), deraileurs, brakes, 700x25 aluminum. SUNBEAM FRAME NUMBER DATING. 1909 = 96,739 (declared) 1910 = 101,700 (calculated) 1911 = 106,700 (calculated) 1912 = 111,642 (declared) PREMIER FRAME NUMBER DATING. BEESTON HUMBER FRAME NUMBER DATING. ELSWICK HOPPER FRAME NUMBER DATING. The following dated bicycle frame numbers from the Singer Car Club (not guaranteed): 1903 – 142069. 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. Little is known by the author of any Gitane models which pre-date the late 1960’s. There are few, if any, specimens in existence in the USA, and more information would be welcome regarding the bikes of the 1940’s, 50’s and early 60’s. Q: Where can I locate the serial number on my bike? A: Almost all of our serial numbers are located on the bottom bracket shell of the frame. Some newer models will have a non-removable sticker on the down tube near the bottom bracket. Specialized serial numbers typically start with 'WUD', 'STT' or 'STE'.

The best chance at recovering a stolen bicycle is having a registered serial number. These numbers are used by police across the nation.

Where to Find It

The majority of serial numbers are located under the bottom bracket where the two pedal cranks meet. Turn your bike upside down and record the number.

If there is no serial number near the cranks, you should check other common places including the front headset or rear stays. The diagram (below) indicates five of the most common serial number locations.

How to Register without a Serial Number

If you can’t find a serial number, you can still register your bicycle with DPS. To do so, bring the bicycle to the station, located in Parking Structure A (PSA). We can provide you with tools to engrave your driver’s license number on your frame. We’ll use this as alternate identification to the manufacturer’s serial number.

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

Giant Bike Serial Number Location

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.

Serial Numbers Nero

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.↩
