Insane Bike Tricks by Tim Knoll Will Blow Your Mind [VIDEO]
It's not something you are going to see while watching the X Games, but the tricks that Tim Knoll performs on his BMX are totally extreme! Rolling through the streets of Wisconsin, swinging on street poles and riding UP stairs, Knoll does the kind of tricks you would think could only be done in a video game.
Remember kids, always wear a helmet. Right, Tim?
