Just watched the you tube of this, and being old have a few questions;
1) what sort of bike, wheels and brakes is used for this sort of stuff - generously curious is it bmx / mtb some form of combo?
2) If a normal bod rolled off say, a substation hight building how hurt would they end up or can you pick stuff like this up - obviously not at 44, overweight and with a dodgy back!
