Bmx Serial Number Identification

GT Serial Numbers - BMXmuseum. Here is an email I got from an actual employee of GT: 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. The next part of the serial number is eight numeric digits.

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.

The first thing everyone wants to know when the buy a second hand GT BMX is ‘how old is it?’ Reading the GT serial number and finding out the build date is an important part of any BMX restoration. Once you now when the old GT BMX bike was built it’s much easier to find out what model it is and also look at the original parts lists and colours from the bike makers catalogues.

Serial

A while back I spend some time investigating how to read mid-school and new school serial numbers on Mongoose BMX bikes.

After buying and restoring a number of older mid-school and new school GT BMX bikes I also need to to figure out how to crack the GT serial numbers to get the same build date information.

It didn’t take long to realise there were many similarities when looking at GT serial numbers and Mongoose serial numbers. The placement and sequence of the numbers is stamped in the same place under the bottom bracket. Many of the GT serial numbers start with the same letter sequence. After a bit of digging around online I soon realised that GT BMX bikes and Mongoose BMX bikes were owned by the same company and also made in the same factories in Taiwan. In fact look closely at many Mongoose and GT BMX’s from the around 2000 to 2010 and you’ll see many similarities in frame design and geometry. This is probably not true for all of the bikes in either range, but there were a number of bikes that were identical apart from the logo stamping. Anyway that’s a post for another time.

As with the Mongoose serial numbers there are many posts from forum members around the world on old-school GT serial numbers, but very little on mid-school or new school.

Of course there are also many variations in GT serial numbers and I have focussed mainly on cracking the new-school numbers for now. That is bikes made between 2000 and 2010, and those bikes made in the Taiwan factories with specific serial number sequences. There will be bikes that are different, if you have any examples of where this crack doesn’t work, add a comment below.

GT serial numbers are usually found stamped on the bottom of the bottom bracket of your BMX. This is not always the case and there will be some bikes that do not fit into this formula.

For mid-school GT BMX bikes built in Taiwan through most of the 90’s with a serial number that begins with 4 letters before the series of numbers. The 3rd letter corresponds to the year of manufacture.

1991-2000 – 4 letters at beginning, 3rd is year

A B C D E F G H I J
91 92 93 94 95 96 97 98 99 00

The 4th letter indicates the Month

HFBH00000 – 4 letters, BH are the dates. B is the year (1992), H is the month (Aug)

For new-school GT BMX bikes built through most of the 2000’s with a serial number that begins with 5 letters. The 4th letter corresponds to the year of manufacture and follows on from the mid-school serial numbers.

2001-2010 – 5 letters at beginning, 4th is year

K L M N O P Q R S T
01 02 03 04 05 06 07 08 09 10

The 5th letter indicates the Month

A few examples are:

HAMRF00000 – 5 letters, RF are the dates. R is the year (2008), F is the month (Jun)

HAMOI00000 – 5 letters, OI are the dates. O is the year (2005), I is the month (Sept)

Please note: The GT serial number will give you the build date of your GT BMX. Frames were normally manufactured the year before being sold in bike shops. So a build date on a frame of 2003 usually means the bike was sold in stores in 2004.
