Got this from Pete over at iBike, definitely some mad, off road fixie skills:
You might have already seen this if you have been to his site before mine, if not, I hope you enjoyed the show.
Here is custom bike builder out of the biking capital of the US, IMO, Portland, Ore. Ahearne Cycles. Check out the custom bike built around an Endo Morph 4.0! Holy smokes, I'd love to try a Pugsley fixed!
Looks like I am not the only one riding mountain fixed, check out his guy.
Well this bike is no mountain bike but I like the way the guy describes the build. Fixed Huffy. In my book, if it's got fat tires it's a mountain bike, even though this bike is touted as a winter commuter.
