In reply to DaveHK: I did this 2 summers ago. It is a magnificent walk, full of a variety. I can imagine biking it however there are some really rocky steep ascents that I know I would personally have to carry the bike for which I imagine is exhausting. I did it in July and there was still a lot of snow in places and in some parts it seemed maybe too deep for a bike but i'm not an avid biker so not too sure on that.
There are quite a few scree traverses. Also one section where you traverse a mountain on a very small path that would be very dodgy to bike on unless you has super balance. I was basically creeping around it worried to even walk briskly! but I used to be a bit of a wuss back then. I think going on a bike would be excellent fun just do lots of research...that video i good.
Good luck!
