Riding a bicycle with abnormally large tires, is much different than riding a bicycle with "normal" sized tires. Especially when riding it fixed. Right off the bat, the most noticeable thing is effort required to make them move. Second and probably the oddest, is the inertia they carry once they are moving. My road fixie sports nice little 700 X 23s. Very easy to slow down using only yee legs. Skids, no problem. On an overweight snow bike it's a much different story.

I've made a huge improvement to this bike, simply by adding an 18 tooth BMX freewheel. 21 on the chain ring gives copious amounts of climbing ability and the down low to grunt through mud and snow (the whole reason I bought this bike) and now being a free wheel, you can actually use gravity in your favor every now and then. Rather than having to resist the affects of gravity on a 35lb bike, you can enjoy it as the big fat fatties roll over anything and everything in their way. This bike is a really hoot at speed. Yes, I said hoot.

This frame was definitely not designed around the Endomorph tire, but I think it will do the job and just sneak by.

Sweet Bike. I agree with your statement on Fat Tire riding. I have
700x42's on my Trek Fixed Gear and can barely slow this down even slow speeds. I use the front brake all the time. I also use platform pedal rather than Shimano 858's that I prefer on my other bikes. I also ride a unicycle and my latest ride has a monster 20x4 inch tire and that huge volume takes a lot of work to get her rolling.
