Danny MacAskill of Inspired Bicycles... got skill

trail bike tend to have fixed hub (but freewheel crankset), not sure how it work, althought I don't know why the backpedal.

no they dont? he was pedalling backwards so that he could roll backwards

they do have fixed hubs, has been for years.

wow, love the corkscrew off the tree, and that guy has got balance.
regarding the hubs, the ratchet mechanism of some hubs, dis-engages when going backwards.
it's called a freecoaster hub.

SOme trials bikes have what is known as a front freewheel, and run a rear fixed wheel.

We have a couple of trialsers on the forum let them explain.
I love the song, one of my favorites.
