Modern GT bikes feature the bicycle's serial number on the underside of the frame and will be accompanied by a bar code: Vintage and older GT bikes may have serial numbers placed on other areas of the frame such as the seat stays next to the rear dropouts or the head badge.

  1. Damage resulting from improper assembly or maintenance, or from installation of parts and accessories not compatible with the GT bicycle, is not covered. All labor charges for warranty service are the responsibility of the bicycle's owner.
  2. I don't understand the serial number on my limited edition bike. I thought there were only 250 made? All of our limited edition bikes are available as complete bikes as well as framesets.

How can I determine what kind of BMX frame I have if I there no decals on the bike when I got it? I got it from my dad who found the frame and we put it together, but I am clueless as to what brand or make it is. Can someone help me?

There was a time when bikes (and cars, and food mixers, and whatever) were manufactured to last, and the same model would be manufactured and sold, unchanged, for many years.

From somewhere in the 90's, there seems to be an obsession with the NEW, so now bikes (and cars, and cell phones, etc you get the picture) change their designs overnight, so people might want perhaps to purchase a NEW one every year.

To make matters worse, in the world of bikes there has been a relative epidemics both from bikes manufactured in Asia (which might or might not be a Bad Thing, depending on perspective) and WalMart bikes (which are always Evil).

So, if your bike is a 'vintage' bmx, I think the best to do is to go to an oldschool BMX bike store and ask the shop crew. There are some bike models which are very distinctive (for example, the classic GT triple triangle), and folks used to see the same bikes over and over might remember some subtleties.

But if your bike is very new, then I'd say it's nearly impossible. Sometimes bikes from two different brands are identical except for the logos, and sometimes bikes that are SUPPOSED to be identical are not, just for being from different batches.

In the end, it matters most to know if your bike is GOOD (aka, real bike), or if it is just a Bicycle-Shaped Object, which I hope it is not.

Hope this helps!

LOOKS like a BSD from pictures I just saw from googling BSD frames, didn't he also say it was a Fit? Seems pretty sketchy. I'd email the serial number to BSD and see if they can verify it
the letters on the right, do they start with a T?
looks like it says TOOLO21
TOOLO
BSD Too Loose 21'?
Maybe, look similar anyone?

notable things are the gussets, integrated clamp, slightly concave BB
my money's on it being a BSD Too Loose

Yeah could be. I think that's it. I was thinking forever trying to think of frames that start with t o o l o but none came to mind. Good job I think that may be it.

Should be
here's the frame promo

Antony Lille and the BSD Too Loose frame from BSD on Vimeo.


seems to hold up to a hell of a lot of drops and stuff. he's pegless, but I'd assume it will hold up to light peg use, maybe more peg use. Can't say for sure, never owned one or knew anyone with one.

Yeah, it's a BSD Too Loose, look at the seat stays.
