Woa

Thats just mental, but i would LOVE to do it though

How can they brake while going down stairs I don't know......

Pretty slow course, but quite interesting anyways.. Now I'm going to spend the next couple hours looking at downhill mountainbiking videos...

Quote from JJ72 :

they use the back brake i gues coz if you used the front ones ud go arse over tit

thats pure insanity i want some

when your going fast enough you just brush the stairs so hard braking works less well so you have to brake a lot earlier. it's good fun though.

I really miss biking, but my shins are very happy about it

If you lose brakes you're dead

foot between back wheel and frame can save lives
