Vintage mongoose Serial Interpreting the Serial numbers and featureson BMX Products, Inc. Frames. Identifying the serial numbers on the early Mongoose frames is actually quite easy and intuitive. For the most part the early Mongoose frames from 1. For example, a frame from 1. A feature of an early 1. The brake tab on these frames is rectangular in shape. Some time late 1. K Frame Serial NumbersThe early 7. Another feature of an early 1. Note the flared shape of the 7. A further feature was the headtube was offset to extend more to the bottom than it was to the top. It is our guess that it was done this way to allow clearance for the squarer shoulder on Ashtabula forks. This feature carried over for the first few years till the ashtabula forks were replaced with the more rounder style Tange made forks. In early 1. 97. 6, the letter C was added to denote Cromo During the early production of the Mongoose frames they were made using 1. Chrome Molly tubing. Both frames looked the same but we need some way of determined the difference due to the frames being nickel plated or powder coated paint ,it was impossible to tell the difference in the material for warranty reasons. The letter C was used for chrome molly. C1. Another feature of an early frame built in 1. In May 1. 97. 6 the serial number process changed again with the addition of a month code. From here frames were stamped with the letter C for Cromo, a letter for the month, and a number for the year of production. It was around febmarch 7. Of course these are general guidelines in identifying Mongoose frames and there are the anomalies to this process of serial number identification. The serial numbers were hand stamped on the bottom bracket tubes then packed in empty beer boxes waiting to be welded to frame tubes. Frame Number. Usually the frame number will be something with a T at the end ex VSX1T for a P200E. Engine and Frame Numbers on Classic European Motorcycles.

Placement of Serial Numbers Like the 1 st generation Colt 1860 Armies of the 19 th century complete or partial serial numbers are to be found on all major parts of. Trek bicycle frame serial numbers SNs are stamped into the bottom of the bottom bracket, or more rarely at the lower end of the seat tube. The dates coded in the. The frame components were manufactured in different stages and or departments and some of the parts were exhausted quicker than others, it this process that lead to some of the frames crossing over to different years, especially during the end of the year. RECO Racer Engineering Company manufactured frames for BMX Products, Inc. BMX Products, Inc. RECO was a frame welding company that BMX Products, Inc. BMX Products Inc. RECO and eventually bought them out. So serial numbers that ran from May 1. March 1. 98. 1 will have three digits in sequence overtop the serial number of that frame. Lets look at some serial number examples below to get a better understand how the process worked. This guideline also applies to Team Mongoose, Supergoose, Jag, Blue Max, Roger De. Coster, Super X, and  Moto Trac frames. Each frame had a combination of three key numbers or letters. For example  CH8 1. Again, the C stands for Cromo where the frames were manufactured. The next letter in the sequence is the month code. A January. B February. C March. The next number is the last number of the year the frame was produced. The rest of the serial numbers are sequential and are the number of frames produced in that series. NB Super X has an X instead of a C in the serial number. The Team Mongoose and Supergoose frames are a little different. The same coding applies to the first part of the serial numbers as we discussed above, however, if a capital T is in front of or above the CXX  it indicates that it is a 1. Chromoly frame.  The Team Mongoose, Team Minigoose and Supergoose, all should have a T in this area. Moosegoose, TwoFour, TwoSix, and the Kos Krusier  also have 1. Chromoly tubing. Another feature of a Team Supergoose frame is the flattened seat stay where the chain passes it. This was done to give better clearance for the chain. Very early team frames had a T but without the flattened seat stay, but these are very few and were in 1. NB a Supergoose is just a full cromo team frame that has nickel 7. As opposed to a candy coated full cromo frame team frame. NBB In 1. 98. 2 and onwards, a Team frame was also offered in Show Chrome as well as red or blue candy coat. Supergoose frames without the flat seat stay. Serial numbers from 1. In April 1. 98. 1 and onwards the frames were coded differently. The C was dropped and they started out with a single letter followed by a sequence of numbers. The frames were still made in Chatsworth up until 1. Moorpark. This applies to all frames made, EXCEPT those starting with the letter M as these frames were made in the Merida factory in Taiwan. As before, the letter indicates the month and the first number or the second digit in the sequence indicates the last number for that year. Also of note is the T for team, was also dropped. When they dropped the C, it was realised that there was no need for it, as there were other ways to ID a TeamSupergoose full cromo frame. There was a few crazy months around April, May and June in 1. So there is actually a month or more where there was a TeamSupergoose frame that had no T in serial but still had old style dropouts. The easiest way is to check the brake bridge for the extra two slotted holes that were added. These extra holes were only on the full cromo frames that had the step down type dropouts. If your frame has holes in the dropouts, BUT does not have 3 holes in the brake bridge, its NOT a supergoose, even if its chrome See dropouts page here. J2. 00. 99. 81 according to this serial number the frame was manufactured in October of 1. Sometime in 1. 98. USA made frames from post gusset era, still had the month first, then the year but they were stamped not on the bottom bracket but on the brace behind the bottom bracket. All USA made frames after they dropped the C were month, then year, then serial number. As a general rule anything with a Gusset behind the head tube was manufactured in the USA. There are a few key components to look for on a BMX Products, Inc. Gusset at the front behind the headtube. A round hole below the upper seat mast. Unique Heliarc weld pattern heli arc is another name for TIG. Its proper name is GTAW, or Gas Tungsten Arc Welding. The heli in heli arc comes from the shielding gas helium that was used. NON GUSSETT FRAMES POST 1. FRAMES. To start with, any frame with a serial number starting with M was made in Tiawan in the Merida factory. In 1. 98. 2, BMX Products started to manufacture a new range of non gussett frame starting with the Pro Class 2. Then next came the first Californian and Expert frames and were USA made, while they were getting setup for Tiawan production. The top of the range frames were USA made, ie Pro class, Rupe, Supergoose. USA made frames continued the standard USA numbering. After the company was sold to Service Cycle, it seems all frame production was moved to Tiawan. We have been told that when the company was sold the new owners only wanted complete boxed bikes and the rest of the stock of frames were destroyed. So to start the decoding of these serial numbers.
