First things first, I think this vid is class, have you ever tried to ride a wet mossy river bed at a speed way harder than what it looks and Chris does this with style and ease
Now roll back 5/10 years and "street" bikes were getting slated as non trials bikes and more like bmx........ Roll back 10/15 year most trials bikes had seats of a fashion and were short and low bb.......(like street bikes) 15/20 years ago trials bike and mtb were almost the same and some trials bikes had sus forks and gears and also used mtb wheels/tires
I learned to back hop on a full sus in the mid/late 90 and i feel like the age of the do it all bike is making a come back again just like mtb went from all round to xc/dh/4x now to "Enduro" all mountain
Dh racers train on motocross in winter, xc riders train road bike, bike trials a lot of moves came from mototrials and vice versa
So to class this is as trials................. why do we have to class anything 2 wheels and terrain does it for me
