Amazing death defying bike ride

It does not even occur in his mind that a small slip will mean a sure death but the way he does it, he makes it look so easy and safe ! Unable to fathom what motivates him to risk his life - is it the sheer thrill of defying death or pushing oneself beyond limits or a fool hardy seeking attention. 

Whatever is the motivation to the rider,  I was getting goosebumps watching this guy biking on the mountain rocks ! Amazing !
