i think what is done on a bmx cannot all be done on a mountain bike, watch some bmx video mtb is soo far behind. As for mtb is harder, true, but who cares cause if you can do cooler tricks on a bmx, in my opinion, it doesn't matter if you are doing tricks on mtbs that are done on bmx more easily. they are both bikes, if you can do sicker tricks on a bmx you win wheather mtb is harder or not. imagine a competition where mtb is competing with bmx, mtb lands decade, bmx lands decade too 360, yes comeupbmx there is a vid, who wins. HUGE NUB "Thats harder on a mtb blahblahblahblahthththtth" decade to 360 still wins cause it is soo dope. enough with things are harder on mtb, harder to the point of impossiblity. don't sound like a nub, please and thankyou
