1976 Mongoose Motomag

Late 75 build, sold as a 1976 model. Small seat stay gusset confirms this.

1976 mongoose motomag bmx bike that I built in less then a week using era correct parts i had from the 70's . New mongoose motomag decals and new CHENG SHIN C-183 tires where used to finish off this bike. I'm still looking for some clear winners circle grips to replace the black ones on the bike now. Also i have some non stamped black mongoose pads on the way and this bike should look nice .

Beautiful build! Is that the original nickel? Looks amazing. That top tube really does look short, though!

lambohaha · 2006-11-03 7:49pm

My cousin had a shorty like that and I rode it once and only once too. My knees hit the bars and my feet came off the pedals and I hit the pavement, hard. No more shorty for me after that. Still a beautiful bike though .

original nickel with new mongoose decals top tube is 2" shorter .

haywardbmxer · 2006-11-03 8:00pm

lambohaha I'll have to ride it when the weather clears up to see if my knees hit i have a few other short frame but never got around to riding them i'll let you know.

Just don`t do what I did. I was riding pretty hard too. It was also about 20+ years ago that that happened.

IF anyone has a pair of grips in clear like the ones i now have on the bike i could use a clear pair new or used .I have other mongoose parts to trade or let me know what you want for them. thanks

Fiorst year was said to be 78 but some speculate there was one made in 77 with a coaster brake tab. I have pictures and details but most common knowledge will say 1978 and made in blue or red! The early ones would have Araya 7b silver rims, Roger DeCoster chrome fork and Mongoose suede seat. They also would have 170 mm Dura Ace cranks, MKS-BM1 black pedals.... and the list of expensive to find goodies can go on...

Here is a link to my 1980 team mongoose .I have been working on a 78 and 79 team mongoose i will post photos when there done.

What is the serial number on your bike? I have 11994 and 10983. 11994 is a shorty and is my bike I received in late September of 1975 (I recently found some supporting documentation in my mothers journals). The other frame with the earlier SN, was the long version and was delivered to my neighbor about a month later. I spent several years tracking the long frame down and have now located the original Simi Motomag I's.

10983 has the square coaster brake tab and 11994 has the upside down mushroom shaped tab.

11994 is nickel and 10983 is red.

haywardbmxer · 2007-06-08 9:03pm

I think that one is 12834 made late 75 somewhere around Nov thanks

haywardbmxer · 2007-06-10 1:42pm

frizzbat · 2007-08-13 3:30am

Your builds are always great...good work!!!

Unkle Stinky · 2008-05-11 9:49pm

impressive bike!!!!!!!!

MrWillys · 2008-06-19 4:15am

This is a good looking bike. I remember picking walnuts so I could buy my first set of Motomags right about 1974, 0r 75.
Keep up the good work. One day i'll re-create the Schwinn Stingray conversions we started with.

mongoosedrummer · 2008-09-18 10:34pm

I've been looking at this "75" for a while and I am wondering if it may not be a 76 frame...

The seat stay "triangle" doesn't seem to flair towards the top like the 75's and also the coaster brake tab seems more of the one ply "squwished-hourglass" shape rather than the two ply "trapezoid" shape of the 75... It also appears to be Chrome plated not Nickel.

I surely could be wrong and no disrespect to Hayward at all, but it just seems that way from the pics. Nice super clean build though!!!
