The 2011 Stolen Sinner Build Kit BMX ($350) is a cool concept of high quality BMX bike you can assemble yourself. Everything you need to build a bike is there besides the frame. If you do not trust anyone when it comes to your ride, the Stolen Sinner Build Kit BMX is for you. It comes in Black, Matte Electric Blue and Matte Electric Red (picture shown). Here is the final result after assembly by the way.
Here is an embedded video of a guy using the Stolen BMX. Pretty amazing stuff.
