Very smooth and flowing rider compared to most who do the same sort of thing. No experience of riding over rocky things but I would imagine having very wide tyres is going to help rather than hinder.
50/50 I expect, on the one hand less pressure should make it more consistent, on the other, I’ve crashed my fatty more spectacularly, and more times than any XC bike I’ve had. On some surfaces (dry dusty dirt) it’ll drift forever, even when pedaling out of corners, and you look like a hero. On the other, there seems to be absolutely zero grip on roots. There’s no grip with normal tyres, but fat tires just seem to stick to the root and slide you along it. I’ve wiped out going uphill on rooty switchback corners! Going down my record was 3 big stacks on an hours XC ride, each one the same, either the front or rear just let go so quickly there was no reacting to it.
Also fat bikes tend to have a big BB drop (80mm or so) on account of the ~30″ wheels, which makes manuals hard as when you push through the pedals the axis is below the axle so you’re not getting any lift (the chain stay want’s to get longer as the BB comes up) because you’ve actually getting further away from the rea axle. A trials bike has a BB above the axles (or at least inline) which means when you push the chainstay is getting shorter and the front wheel get’s easier the higher it goes.
That and weight, Ok a motorbike is heavier, but has F+r suspension to load up, and an engine to push you up stuff. Fat wheels aren’t exactly light.
