You wouldn't see it coming, but you'd hear it from a mile away. Before you know it, pow, the wind gets knocked out of you and you're on your knees praying you'll breath again. That's basically the feeling this bike gives its owner. Like he's in a squared circle with gloves on. When the bell rings, they go at it because this bike is pure toughness. Raw, stripped down, bare bones and kick ass. You have to know what you're in for if you're planning to go a few rounds on this thing, tough guy.
