Not for the faint hearted, check it out..

Of course, thereís an inspirational story behind this video as well, which many of you will know. On a day off from filming of the video, while working on his trials bike at the Moto GP at Silverstone, Martyn was in a bad crash and was paralysed from the waist down.

The trials champion has got a remarkably strong mentality though, and a positive attitude that should be an inspiration to all. He got on the phone and brought Chris Akrigg and Danny MacAskill in to finish the video, and it goes without saying, itís a work of art.

Not only do you have Ashton taking on some seriously slippy-looking water slides, riding on an aeroplane and going flipping mad, thereís also Chris Akrigg inexplicably riding across a log in the woods, and the one and only Danny MacAskill nailing a full loop.

Yes, MacAskill may have stomped plenty loop-the-loops since this edit dropped, but let us remind you that in this video, heís riding a road bike. Itís absolutely nuts.
