Haro Shredder.

If I were getting a new bike, I'd get this. The Haro Shredder. It has 3 piece cranks, awesome pegs, and awesome brakes. The frame is good for everything; street, dirt jumping, vert, and flatland.
The only thing that I would replace are the bars. I would get some Dave Mirra bars or something just to make it look cool. The Haro Shredder costs $298, which isn't bad at all.
