Bicycle Serial Number Chart

Your guide to old Mongoose serial numbers. Find our what year your BMX was built and sold and date mid school and new-school bikes made between the mid 90’s to mid 2000’s. The guide covers many serial numbers but not all. There were many different factories making Mongoose BMX bikes and all had different serial number codes.

We began collecting serial number information in the 1950s and we have our own proprietary charts that document each model and serial era for many bicycles. We acquired factory serial number and model number information directly from many defunct bicycle companies such as murray and monark-silver king while they were still in business. Find the serial number on the bicycle. Schwinns produced between 1960 and 1969 have serial numbers on the right rear axle mount (this mount keeps the wheel in place). Look for the serial number on the lower head tube (right above the wheel on the front of the bike) for. Since used-bikes typically sell below their asking price, our analysis tracks actual sale prices to determine Private Party Value. Real-time Algorithm Our algorithm considers a bike's age, brand, type, frame material, suspension, condition, components, wheel size, modifications, manufacturer and retailer discounting and the depreciation that.

Mongoose serial number information has never really been properly documented, possibly lost as the company changed hands and moved production. However, there are a few BMX restorers who have painstakingly attempted to decipher these multi-digit mysteries.

A big part of buying, rebuilding and restoring old BMX bikes, is knowing exactly how old they are. When I started looking into finding out how to read Mongoose serial numbers I found plenty of information on Mongoose BMX bikes made in the 80’s and early nineties through google and BMX forums. The problem was there was no information helping to date Mongoose BMX bikes built from 2000 onwards. It seemed nobody figured out how to read the serial numbers.

Older Mongoose bikes made through the 1980’s had pretty easy serial numbers. Generally the year and month of build was stamped as the first part of the serial number. For example my 1986 Mongoose Expert has a serial number M6EG0652. The first number (6) relates to the year – 1986. The next letter relates to the month (E) is May based on the convention January (A), February (B), March (C), April (D), May (E), June (F), July (G), August (H), September (I), October (J), November (K), December (L). It is assumed that the G0652 is the production number. There were a few variations on this type of serial number, but usually they were pretty easy to work out.

There are much more difficulties when looking at Mongoose serial numbers through the 1990’s and 2000’s. I spent quite a bit of time looking into these numbers on a few of my bikes as well as checking against other Mongoose BMX owners to see if my serial number crack was right. It seems to hold up and here it is.

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

Mid-school Mongoose BMX bikes built through most of the 90’s have a serial number that begins with 4 letters. The 3rd letter corresponds to the year of manufacture.

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

The 4th letter indicates the Month

A B C D E F G H I J K L
Jan Feb Mar Apr May Jun Jul Aug Sept Oct Nov Dec

A few serial number examples are:

HFGB00000 – 4 letters, GB are the dates. G is the year (1997), B is the month (Feb)

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

New-school Mongoose BMX bikes built through most of the 2000’s have 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.

J K L M N O P Q R S
00 01 02 03 04 05 06 07 08 09

A B C D E F G H I J K L
Jan Feb Mar Apr May Jun Jul Aug Sept Oct Nov Dec

A few serial number examples are:

HAMME00000 – 5 letters, ME are the dates. M is the year (2003), E is the month (May)

SAJPJ00706 – 5 letters, PJ are the dates. P is the year (2006), J is the month (Oct)

Identify Bicycle By Serial Number

Please note: The Mongoose serial number will give you the build date of your 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. This is the case with the 2003 Mongoose Brawler 24 below. The Serial has a build date of 2003, the 2004/004 on the stickers indicate this was a 2004 model.

I have confirmed this Mongoose serial number crack many times against bikes that have been known to be purchased that year, bikes with distinct graphics and colours and checked them against Mongoose BMX catalogues.

Redline is the third brand of new school BMX that I have researched and cracked the serial numbers for dating the age of BMX bikes. Mongoose serial numbers were first and then GT serial numbers. When rebuilding and restoring old BMX bikes it's extremely helpful to know exactly how your bike is.

This post is intended to be used as a helpful guide to help read your Redline serial number and find out what year your new school Redline BMX was built and sold in bike shops. The serial number guide will help date Redline BMX bikes made between 2001 and 2009. This guide may not work for all Redline BMX bikes built between this time and I have listed below which Redline serial numbers it does work for. I spent quite a bit of time looking into the Redline serial numbers on a few of my bikes as well as checking against other Redline BMX owners to see if my serial number crack was right. It seems to hold up and here it is.

The above bike is a (2005 built 'P') 2006 Redline Proline Flight 24.

2001-2010 – 2 letters at beginning, 2nd is year

K L M N O P Q R S T
00 01 02 03 04 05 06 07 08 09

A few examples are:
HS00000 – 2 letters, S is the build year (2008), Sold in 2009
HP00000 – 2 letters, P is the build year (2005), Sold in 2006
HR00000 – 2 letters, R is the build year (2008), Sold in 2008
