How to ID a JMC

February 2, 2010

Ok this is just a start, so this section will improve over time.

1976 first prototypes had XP in the serial number. Example JMC XP1.

1977 first production bike was JMC1 (March 77) and first production long frame was JMC20 (April 77). The frames were numbered in order.  The frame came in two sizes. JMC Short Standard with a 17.5 top tube that angled down toward the seat stays. The other size was JMC Long Standard with a 18.5 top tube that was more level. JMC would make these two models till the end in 1985.

Bottom Bracket Brace

The early models had a elliptical bottom bracket brace behind the BB. In 1979 sometime (exact month to be determined) they switched to a square box. In 1983 they would eliminate the box (exact month to be determined) and the chain stays went directly into the bottom bracket.

Serial Numbers

These can help you date the bike with known certified bikes. All JMCs were numbered in order starting with JMC1. In 1983 the first two digits were the year of manufacture but the run numbers were still in order or started over.

“JMC” in front means it is either a Long or Short Standard or very early Black Shadows.

“K” was originally for Black Shadow and the later Shadows which were same frame just now in more colors. The “K” was added in late 1980. First ones just had “JMC”

“XL” was for the 3.1 XL. 3.1 was the weight and XL stood for Xtra Lite.

“CR24” or “C” was for Cruiser.

“P16″ was for a 16” Pit Bike.

“DY” was for the Darrell Young model.

“AP” was for the Andy Patterson model.

Time Line

1977 (March) JMC Short Standard introduced with #JMC1

1977 (April) JMC Long Standard introduced with #JMC20

1980 (February) JMC introduced the Mini with #JMC1801

1980 (March) JMC Black Shadow was introduced with #JMC2175.  Came only in black at first.

1980 (May) JMC 3.1XL is introduced with #JMC2457. Named by Matt Raymer of Mongoose and Oklahoma fame. It is same size as the Short Standard but with smaller lighter tubing.

1980 (November) JMC Black Shadow now also in Chrome with #K3733.  Serial numbers begin using “K” to designate Black Shadow/Shadow. The bike was designed for Kim Jarboe hence the “K”.

1981 (July) First red Shadow made for Darell Young #K6097.

1982 the Pit Bike “P16” is introduced with #P16-1 [only 110 made]. These bikes jump out of sequence and are starting from 1.

1982 the Shadow now comes in other colors.

1982 First JMC Cruisers are made.

1982 (September) the JMC JR Mini was introduced. JR stood not for Junior size but for Justin Roos.

1983 (October) first Darrell Young models are made.

1984 (April) JMC Micro Mini is introduced. [only 85 made]

1984 (August) JMC Andy Patterson model is introduced [only 333 made]

    The frames originally had elliptical down tubes and bb spacers. ’76-’78

    When we ran out of elliptical tubing we changed to air foil or “tear drop” down tubes.
    I believe, late ’78 early ’79. It was no surprise since we were already using the air foil tubing for our forks at the time.

    The first air foil down tube frames had elliptical bb spacers until we exhausted the inventory of elliptical spacers, then we changed to rectangular “box” spacers. ’79

    The first air foil tubes were installed 180 degrees opposite the later airfoil down tubes.
    “large radius at the top on early, large radius at the bottom on later frames”. I don’t recall when they were changed, it was either ’79 or ’80.

    I just came across this website, and wanted to know how may Black Shadows were made? What was the very first No.? I think I may have an older JMC the No. reads K3984. Is there a way to find out the history of my bike? I remember my grandmother buying the bike for me from some guy when I started to race back in the day. I remember the guy said he was getting to old to ride and wanted a kid that was going to race it to take it. I raced in Cincinnati with Matt Pohlkamp until our track went under. Matt keep going and I put the bike up. The good old days, very fun.

      You can find Jim Melton on eBay. He sells certificates that tell you exactly when your bike was sold and to whom. It even tells you the original color.
      Money well spent. The first thing I bought for my JMC. Still havent restored it lol. Matt was scary good. Never met him though.

    Hey Team,

    Awesome site, Full of amazing information & flashbacks to what once was..

    Recently I uncovered some bikes I had stored & forgotten about, Wondering if you can help in the identification of what they really are & if possible what colour they were when made, also if possible, was there ever a colour chart that was specifically used for these amazing bikes?

    Frames are:

    K84496 (Currently Painted Candy Apple Red)
    K85126 (Currently Painted Dark Metallic Blue)
    K83404 (Currently Painted Gloss White)

    Thank you in advance for any help with the before mentioned

    • April 20, 2013 11:15 pm

      Contact Jim Melton thru JMC on ebay. He has a store there. Order a Certificate it will tell you when it was sold and to whom and original color.
      Colors are simple. Candy Apple Blue or Red. Both were powdered over a Silver base.
      Gloss Black and Gloss White. Chrome was an option in the 80s.
      3 JMCs! you are the envy of everyone that visits the site now lol.

        I’ve just ordered a set of Black Shadow decals as I thought that’s what I had! You’ve informed me it is in fact a Shadow so I need to amend my order. Question is what colour was my bike originally if not black so I can restore and order the correct decals?
        Thanks

      • August 21, 2013 8:02 pm

        It was sold in those years as a Shadow , even the black ones. So original color could be black.
        Get the certificate from Jim Meltons ebay store. That will confirm all the details.

    i have a jmc and the serial numbers are jmc1900 can some one tell me what model and year it is?

    • August 21, 2013 8:00 pm

      Can only tell you its a 1980. For more info on it you’d need to order a certificate thru Jim’s ebay store.

    My JMC Black Shadow only has numbers, no leading letter…what does that mean? The number listed is 4328.

    • August 21, 2013 7:57 pm

      It may mean its not a black shadow.
      Contact Jim Melton thru his ebay store and order a certificate. That will tell you everything.

        Unfortunately I will likely be selling my frame this weekend, so not much opportunity to get the official information. I can say it has one flat bar…wasn’t that the case only for the Black Shadows? That’s for your reply!

    I have Micro Mini # N84.
    The first MM made.
    Did the “N” stood for Norms?

    • December 8, 2013 7:14 pm

      Not sure but that would be a good guess. Hopefully Jim will see this, but in case not I would just contact him thru his ebay store.

    i have a jmc from 1980s serial number K8 4992 any idea how much it is worth

    • September 10, 2014 6:35 pm

      No but it looks to be a 1984 JMC Shadow. Check out ebay to get a certificate of authenticity to find out the details

  11. August 11, 2015 3:44 am

    Have you guys seen an Australian JVC Racing BMX on a Malvern Star Supermax?
    I purchased this on EBay, and have had no luck in researching anything on JVC Racing in Australia (perhaps its just a JVC decal, but it looks authentic to me).

    Thank you

    • August 11, 2015 7:37 pm

      As far as I know no JMCs were ever made using Aussie brands. Id bet the farm on that. It was probably just an old decal added back in the day. Still a nice classic bike you won.

        Hi this is Gary. With jmc49. The frame is a short .Original color white,has the elliptical down tube. Small bb.in 1978 or 1979 my family went to California for vacation.we went to the jmc factory. Met Jim..Tried to buy a frame from him.wouldnt sell to individuals.so he hooked me up with a girl on the jmc team selling her frame. We went to the track where they filmed a chips episode where we met Harry leary who had the frame.and bought frame from him.

    I used to own JMC4. It was Black and Gold. Gold Araya rims w/ bullseye hubs. Dura-Ace Cranks. I have always wondered whatever happened to that bike after I traded It for a Schwinn Cruiser?
