I've seen this video from a number of different sources, and the cyclist is amazing.
When I watch him, I wonder, "how does he see the world?"
Think of a little kid, everything is big and an obstacle: chairs and bookcases are to be climbed, a doorknob or lightswitch is likely out of reach, counter tops are the unknown.
A rock climber might look at buildings as potential playgrounds, whereas an architect might notice the design, and a contractor might notice the workmanship.
Watch all the way to the end, he does some amazing stunts. Fences and rails are not barriers, they are paths, trees and walls are ramps for him to ride or bounce off, stairs are an excuse to turn a 360, walls are merely steps for him to jump (climb), and curbs are like the cracks in the sidewalk you cannot step on.
At least, that's how I imagine he looks at everyday objects.
