Serial Number Location

Your serial number description STATES that this is a 'Murray of Ohio' manufactured bike. Serial number on bottom bracket means before 1965. The factory was removed from Ohio and located in Tenn. Notice this serial number stamped into the headbadge. Not many serials were done that way, at kleast not on Murray made bikes. This pic is from an AMF made bike. We believe that the 3rd digit, which is a 6, may stand for 1966. Need other numbers to compare against. 882 would be the model/catalog part number.

Trek frame serial numbers (SNs) are typically stamped into the bottom of the bottom bracket shell. In the case of some early 80s Treks, the number is under the plastic cable guide on the bottom of the shell. Just remove the plastic cable guide to see the number. The other place Trek (or their subcontractors) stamped the SN is at the lower end of the seat tube.

Note: The SN on your original sales receipt may not match the one on your bike. Sales persons sometimes had difficulty reading the numbers.

Many early Trek bottom bracket shells have a one or two letter code stamped separately from the serial number. This was made by the individual framebuilder to mark his/her work. On some bottom brackets there are two codes: one indicating the maker of the main triangle and the other for the maker of the rear triangle or perhaps the person who cut and shaped the tubing, if not done by the framebuilder. If you know which mark was used by a particular craftsman, please let me know.

Serialization Date

The dates coded in the serial numbers, or the dates inferred from the numbers, are dates on which the new frames were stamped with serial numbers (serialized). These dates are not necessarily the same as the model year of the frame. At some time late in each year (beginning generally September or October) the frames produced were created from designs, and painted with colors, for the next year.

Hard to read?

Trek serial numbers can be hard to read. Clean the area well, and use lots of light at various angles. A suggestion by J. Hansen can help you read a serial number:

'Rub the area with candle wax of a color that contrasts with your paint. Lightly wipe it off with a rag. The wax stays in the indented area of the S/N. Now you can easily read the number. I have included a photo of the results from my bike. In this case I used a red candle to make the serial number stand out. Note that even with the serial number filled with wax, the leading '0' is almost imperceptible.'

PRIOR TO LATE 1980

Before late 1980, Trek used an alphanumeric serial number scheme. Each seven-character number consists of three letters mixed with numerals. The serial number list and the code for the list are not available from Trek (but hope springs eternal). In the meantime, we have the results of the serial number decoding project:

LATE 1980 TO LATE 1986

Late in 1980, Trek changed to a new numbering system for their frames built in the U.S. The frames were numbered sequentially, beginning with number 000001. The record of the assembly runs was documented in a handwritten journal. Trek (Kevin Tita) graciously provided a copy of the journal for this web site. The list ended in November of 1986 with number 279975. This serial number system actually extended through at least 1997 (see Table II below).

The journal includes run number, model number, frame size, and serial number range. Incidental information, including dates and comments on the frames, appears sporadically through the journal. A 'run' was for a particular frame size and frame model.

We all owe thanks to Luker White who generously donated his time to convert much of the paper list to digital form.

These data were mined to produce bike production by model for each calendar year. The results can be seen on the Trek Bike Production by Model, Late 1980 through 1986 page.

Click on the date link in Table I below to go to the detailed serial number information for that year.

Table I - 1980 to 1986

Notes for Table I:

1. Table I contains dates of frame serializing, and are not necessarily model year. At some time late in each year (generally September or October) frames were built for (then painted with colors for) the next model year. This journal information is summarized by year in Table I. The year designations in the table are approximate; not all of the runs are sequential in time. This may be a result of subcontracting some frame fabrication.
2. For some years, the model number given may be the lowest number (or an X00 number) for a series of models that have the same frame. For example, a 1981 frame appearing on the list as a Model 610 could have been built into either a 613, 614, or 616 bike.
3. Some of the Model 170 serial numbers are 6 digits but do not follow the numerical sequence. A future task is to sort 170 numbers. Some of these are presented in the 83, 84 link at the bottom of the table.
4. Some early and mid 80s bottom brackets were marked with 58TSI or 60TSI. In the early 1980s Tim S. Isaac designed new lugs and a new bottom bracket shell for Trek. The new bottom bracket shell is typically marked with 58TSI (or more rarely, 60TSI). This designation is not part of the serial number but is a model number of the shell. The TSI are Tim's initials. The 58 or 60 refer to the angle between the seattube and the downtube.
5. Some frames in this period have a leading 'A' before the 6 digit number. This may be more prevalent on lower level models. The 'A' may not be part of the SN. Just disregard it when looking up the number in the tables below.
6. Frame Sizes in the SN list below are as given on the paper copy. For some entries, only a two-digit number was given, the extra 1/2 or 3/4 inch was dropped. So - an entry of 22 inches really means a 22.5' frame size, 19 means 19.75', 25 means 25.5'.
7. The list has two major gaps, corresponding to missing pages. Page 9 ends with SN 027870 and the next page starts with 029118. Page 61 ends with 210065 and the next page starts with 215226.
8. The SN list for 1986 has some serial number ranges with annotations about POs (purchase orders) to 'Merida'. These are for Model 800, 830 and 850 mountain bikes and Model 300 road bikes. These were made late in the year, so they probably were all 1987 models. At least some of these were provided to Trek as 'frames only'. One reported SN in these ranges, for an 850, was prefaced by the letters TML. From the serial number list, the number of Trek frames or bikes made by Merida late in 86 totaled at least 8251.
   Merida is a Taiwanese bike company that was established in 1972. It is currently a major, worldwide player in the bicycle business. See http://www.merida.com/ for information on this company.

   LATE 1986 to 1999+

This 6 digit (7 digit beginning in 1993) code extended into at least 1999, at least for some models (generally mid to upper level and made in the US). The number may or may not have a leading zero, making the six digits into seven digits prior to 1993. The model is not available for these numbers but the year can be determined or estimated from Table II below. The information in the table is from serial numbers submitted by site visitors. Our thanks to them. In contrast to the serial number dates in Table I above, the years in Table II represent model years, not the date the serial number was applied.

Table II - Model Years 1987 to 1999

FOREIGN-BUILT FRAMES AND BIKES AFTER 1982

1. Three different serial number forms have been submitted for 1983 Trek Model 400 frames. One, marked 'made in Japan', begin with JS followed by six numerals. The SN was located on the bottom of the bottom bracket. A second serial number is 81765. According to the Trek-provided SN list, this corresponds to a 22' (22.5') Model 400 frame made in 1983. This SN form is for frames/bikes made in the US The number was marked on the bottom of the bottom bracket. The third number is 403300950, which indicates foreign built, but the nation of origin sticker was missing. This number was marked at the bottom of the down tube. It is likely this 400 was made by the same manufacturer as the 1984 bikes described in the paragraph below. For the 1983 Model 400, it appears Trek used three sources for their frames or complete bikes.
   

2. Several 1984 Trek 460s, 420s and 400s have been reported with 9 digit numeric serial numbers stamped on the lower seat tube instead of on the bottom of the bottom bracket. These frames, or complete bikes, apparently were made in Japan by an outside contractor. The numbers submitted are in the range of 401000000 to 440000000.

3. An 8 or 9 character alphanumeric code was used for mid- and low-level frames subcontracted in Taiwan. Most of these bikes were labeled 'Made in Taiwan' (although the sticker often is easily removed). This form of serial number appears to have been used during the period 1987 to 93. The number leads with a T (for Trek?) then a numeral, one letter or two, then five (sometimes 4) numerals. Sean Hickey suggested the first numeral is the year of manufacture, and the letter is the month of the year (A - L). This is confirmed by serial numbers that were submitted by other Trek owners. If there are two letters after the year numeral, the first is the month. The second runs from A through at least Y. It might be a way of extending the 5 digit number series by a factor of 26.

4. A later 8 and then 9 character alphanumeric SN scheme, used beginning in about 1989, also begins with a T (for Trek?). These later T numbers were used on lower level subcontracted frames but do not follow the 2nd and 3rd or 3rd and 4th character date meanings above.

5. Beginning in about 1993 (model year 94), an 8 character alphanumeric code was used for some bikes. It begins with G and another letter (e.g. GN, GQ, GR, GS, GU, GV, GW, GY and GZ). These are followed either by: 6 numerals, or a numeral and a letter followed by four numerals. The first numeral in the SN may be the year of serialization.

JAZZ BY TREK

Jazz is a line of foreign-built, entry-level bicycles that Trek sold in the early 90s. (See the history page for a bit more info and the brochures page for a 93 catalog). There seems to be at least three serial number types:

1. A Flipside model had the serial number JT0116 stamped on the bottom bracket shell. The JT probably stands for 'Jazz' and 'Trek'. The numbers may be the sequential frame number, beginning at 0001.
2. The second type is a 10-character serial number. The first two characters are letters which are followed by eight numbers. Examples are JT09010099 and FI08003231.
3. A Latitude model has a 10-digit, all-numeric serial number: 1230707859. This number also was stamped on the bottom of the bottom bracket shell.

These three serial number forms may mean that Trek used at least three subcontractors for the Jazz line.

MISSING SERIAL NUMBERS

A few owners of early Treks, mostly, from 1976 through the early 80s, report their frames are not marked with serial numbers. A past Trek employee wrote that the police in the Madison and the surrounding area said TREK was famous for bikes with no serial numbers. Seems hundreds didn't get any numbers at all. The serial number guy just missed a few?

Three other possibilities: 1. In the early years Trek allowed, and even encouraged, their workers to use company equipment and materials to build personal frames after hours. These frames often were not serialized. The practice stopped after production was increased, resulting in little available down time for the equipment. 2. The serial number on a repainted frame that was not first stripped, may disappear under the new paint. 3. The number is under the plastic cable guide attached to the bottom of the bottom bracket shell.

Before 1900 there were hundreds of companiesin the United States producing bicycles. Between about 1900 and the mid-1920sthe field narrowed considerably as companies like Schwinn and Westfield boughtout other makers but carried their brands forward. While some of the companieslisted here certainly predated balloon tire bicycles the following are the mostprolific builders of balloon tire bicycles.

Following the story of eachmanufacturer is a list of some of thebadges known on the bikes. These listings are only examples as some companiesare known to have used hundreds of different badges. Distributors or retailerssuch as tire stores, department stores, hardware stores, or any number ofretail establishments that sold bicycles many times had their own badges made.It is important to understand that the badge was merely a brand and notnecessarily the manufacturer. For example the brand “Elgin” was used onbicycles Sears sold before World War II. Sears never made any of its own bicycles.Neither did Firestone, Goodyear, or B.F. Goodrich. In the case of the Elginbicycles many were made by Westfield but some made by Monark and Murray aswell. Colson, Monark, Cleveland Welding, and Schwinn made the bikes for thetire companies.

Schwinn

Generally accepted as introducing the balloon tire bicycle to America Schwinn is probably the most recognized bicycle manufacturer in the world. The company was formed in 1895 by Ignaz Schwinn, a German immigrant, and along with the financial backing of Adolf Arnold formed Arnold, Schwinn & Co. in 1895. At one time Schwinn was also one of the largest motorcycle manufacturers in the United States having acquired both Excelsior (1912) and Henderson (1917). Schwinn designed and built some of the most iconic balloon tire bikes to include the Aerocycle, Autocycle, and Phantom. Although the Schwinn name survives the bicycles are now made in China.

Badges: Schwinn,The World, LaSalle, Lincoln, American Beauty, Cadillac, Ace, Henderson, Excelsior,Mission, American Flyer, Chicago, Admiral, Liberty, and hundreds of storebadges such as Beards (Evansville, IN), Lawlor’s (Lincoln, NE), and Tiger (G.W.Tiger & Sons–Colorado Springs, CO)

Murray Bicycle Serial Number Identification Pictures

Cleveland Welding Company

The Cleveland Welding Company is generally referred to as “CWC” by collectors started producing bicycles in September of 1935 and are probably best known for their Roadmaster line of bicycles. The “Y” frame Roadmaster Supremes of 1937 (aka Bug Eye) and 1938 (aka Four Gill) are some of the rarest and most sought after balloon tire bikes. The Roadmaster Luxury Liner is probably the most well-known model from this company and the “Shockmaster” is arguably one of the smoothest riding spring forks ever made. CWC was sold to AMF in 1951 but the Roadmaster brand lives on although these bicycles are now made in China.

Badges: Roadmaster, Supreme, Packard, Hiawatha, Ridewell, Ben Hur, All American, Trojan, Pilot, Hawthorne, Trail Blazer, Speed King, Vim, Movie Ace, Fleetwing, Champion

Monark

The Monark Silver King Inc. started as a battery manufacturer and began producing bicycles in 1935. What sets Monark apart from other manufacturers was their use of aluminum in construction of their bicycles as well as using a 24” wheel size on these bikes. It should be noted that aluminum had been used in bicycle construction starting in the 1890s. Monark introduced its steel framed bikes in 1938 which included such models as the “Superframe” Five Bar. It is their aluminum bikes though such as the Flocycle, Wingbar, and 26X that most collectors covet. Postwar Monarks include the popular aluminum “Hextube” and the Super Deluxe models.

Badges: MonarksSilver King, Montgomery Ward, Hawthorne, DeVega, Reggie McNamara, Ace,Mahowald, Airman, Firestone

Shelby

The Shelby Cycle Co. of Shelby, OH was formed in 1925 from the remnants of the Shelby Cycle Frame Builders. The Shelby Airflos (Speedlines) are considered some of the most outlandish designs of the late 1930s and are some of the most sought after balloon tire bikes among collectors. In 1949 Shelby built the Donald Duck bike featuring Donald Ducks head whose eyes were the lights. The company was sold briefly to Gambles in 1953 but within months sold to AMF. Badges: Shelby, Flying Cloud, Gambles, Hiawatha, Ideal, Safe-T-Bike, Speedway Special, Supreme, Fox, Western Flyer, Bird, Trojan, Eagle, Pirate

H.P. Snyder

The relationship between the H.P. Snyder Co. and the D.P.Harris Company is one of the more unusual arrangements in bicycle history. Sometimein the early 1900s a partnership was formed between Snyder and Harris wherebySnyder would build the bicycle and Harris distribute them. Harris was also amanufacturer of bicycle parts and ball bearings and its own product line was calledRollfast. Harris distributed the Snyder bikes under the Rollfast name as wellas many others. Snyder built bikes were also sold through Montgomery Warddepartment stores. While Rollfast bikes were high quality machines their designwas decidedly more conservative than a lot of their contemporaries. Anexception would be the Hopalong Cassidy bikes complete with conchos, fringe,and a simulated horse hair saddle. The Rollfast name would continue until 1975when the Snyder Co. finally closed and the relationship between Snyder andHarris was dissolved.

Westfield

The Westfield Manufacturing Co. of Westfield, MA has originsdating back to 1877 with the founding of the Pope Manufacturing Co. Many brandswere manufactured under Westfield but their in-house brand was Columbia. Westfieldbought many bicycle companies such as Miami who made the Flying Merkel, andRacycle among others. Some of the most desirable balloon tire bikes ever madewere produced by Westfield for Sears under the Elgin brand to include theBluebird, Skylark, and Robin. Westfield was also the primary contractor formaking bicycles for Hendee/Indian Motocycle Co. until World War II. The companyenjoyed postwar success but like other American companies succumbed to importsand production cost and ceased operations in 1987.

Iver Johnson

Initially formed as Johnson and Bye & Co. in 1871 in Worchester,MA the company was renamed Iver Johnson’s Arms and Cycles Works when it wasmoved to Fitchburg, MA in 1891. Iver Johnson bicycles were typically high grademachines and manufactured most of the parts for their bicycles rather thanrelying on other manufacturers. The Super Mobike featured stainless fenders, anoctagonal battery tank, a unique crank assembly, and a hornlight. Iver Johnsonceased bicycle production in 1941.

Badge: IverJohnson

Huffman Manufacturing/Huffy

Murray Bicycle Serial Number Identification Guide

The Huffman Manufacturing Company began producing bicyclesin 1934 in Dayton, OH. While its initial offerings were rather plain by 1936the company introduced some exceedingly stylish bikes such as the SafetyStreamline followed by the Super Streamline bicycles. In 1938 Huffman introducedthe “Twin Flex” which was a full suspension bike (front and rear springs). The1940/1 Champion and Mainliner lines are also very popular with collectors.Huffman was one of two manufacturers to produce bikes for the war effort(Westfield was the other) and these military models are highly sought after.The company changed its name to Huffy in 1977 but the bicycles had been brandedas Huffy since 1953. Although the Huffy brand still exists all production is inChina.

Badges: Huffman, Huffy,Dayton, National, LaFrance, Dixie Flyer, Airflyte, National, Snell, Davisflyer, Chieftan, Indian, Belknap, Firestone, Everbest

Colson Corporation

The Colson Corporation was located in Elyria, OH andmanufactured bicycles form 1917 to 1953. In 1954 the Evans Products Companybought the bicycle division from Colson and Evans-Colson bicycles were solduntil 1962. Some of the more interesting bicycles produced were the Hi-Lo whichcontained a rudimentary two speed transmission in the crank hanger and wasshifted by a shifter mounted to the frame. Colson produced some of the mostoutrageous paint schemes in the 1930s on its top-of-the-line Commanders andImperials. Colson used a suspension consisting of rubber cushion(s) on some ofits top models. Colson produced models for both Goodyear and Firestoneincluding exclusive designs such as the Double Eagle (aka Clipper) for Goodyearand the Super Cruiser (aka Bull Nose) for Firestone.

Badges: Colson,Scout, Vogue (girls models), Double Eagle and Double Eagle Deluxe (Goodyear),Firestone Cruiser and Super Cruiser, Wings, Rover, Packard, Pilot, Flying Ace,Olympic, Champion, Lincoln

Murray Ohio Co.

The Murray Ohio Manufacturing Company was formed in 1919 inCleveland, OH. Initially the company made automobile parts but by the mid-1930swas producing bicycles, primarily, for Sears. In 1939 Murray introduced thePacemaker at the World’s Fair held in New York. The bicycle was designed byfamed industrial artist and designer Viktor Schreckengost. Murray continued toproduce bicycles after the war for Sears and others with such notable musclebikes as the Eliminator and Wildcat. In the late 1980s Murray was sold to aBritish investment company and by 1999 bicycle production ceased.

Badges: Murray,Mercury, Elgin, Western Flyer, PENCO, J.C. Higgins, Sears

Manton-Smith

Manton and Smith was a Chicago, IL ornamental iron companythat started building bike frames for other companies in the early 20’s. Fromabout 1936 to 1953 the company manufactured its own line of bicycles. Among themore interesting features found on some Manton Smiths is the fork lock brazedto the head tube. Manton Smith also employed a unique spring fork. The prewar “GoldenZephyr” was perhaps their finest model. Like other bikes of the time they were soldthrough distributors and retailers and a variety of head badges can be found onthese bikes although they are fairly obscure.
