I'm guessing this bike will be fine for a couple years. I've ridden crappy Walmart bikes before, and as long as you don't mind lousy shifting and braking, they are fine. And in a fixie, these are null issues (at least the shifting). Of course, it will be heavy and the frame will be springy, but that's ok if you're not racing.

Those big tires are on it for a reason, however, and the reason is the wheels can't withstand additional shock. And if you put a fixed cog on it, you will probably need a new chain for $10 and who knows if the crank will hold up.
