There are many things about this bike that make it much better for stunt riding. The special chain adds something. The pedal arms are the hot brand for that kind of thing.

  

It's a fixie, so all power control goes through the pedals.

     

The pegs are for "grinding" on ledges and stuff like that. You can see from the bottom view that this one gets used. The front wheel is completely unencumbered so that the handlebars can spin. He also explained that there is a lot more rubber there so that when the bike lands the tires don't puncture. I gather the guy used up a few road bikes before he figured out he needed a bike like this one, which he said "is perfect for the way I ride."
