I am a pretty much natural only rider, but due to lack of transport I have been riding a bit of street.
I rode some railwaylines the other day and did some cool stuff (to my suprise as I thought it would be a lot harder)
When I said the stuff he does isnt hard, I dont mean anyone can just go out and do it, but if I had a few weeks to practise, then a good few of the moves could be done (not all because some are rock hard), it took me half an hour to learn to rear wheel a wall, drop to bash, then go to rear again.
I am building up a 24" bike at the mo so I can go out and do streety/bmxy stuff as my bike is deffo not setup for that style.
so in conclusion: he is a VERY good rider, does some really sick stuff, but I dont think its as good or as hard as a lot of people make it out to be.
