I always find his videos inspiring and depressing in equal measure. So no overall effect I guess
One of the most interesting things in that video is how he uses skidding the rear wheel to slow down a bit. Having done a lot of snowboarding that makes a lot of sense for me. I think it's probably a lot easier to slide out on a bike doing it though.
I'm always tempted after watching his videos to put together a hardcore mucking-around type bike, but I know I'd probably just leave it in the shed...
