The process from how the person uses his body to pull up and how it effects the rear tire and then riding it to setting it down.

I just think it would be amazing to see in slow mo

Agreed. I'd be particularly interested in a "race" type wheelie over a stunt wheelie. It would be amazing to see a racer counter-steer into a turn, spin the rear tire around and pull a wheelie on the way out of a turn. Interesting objects might include the suspension, brake/throttle controls, shift levers, rear wheel, sprocket.

That's drifting and it's actually a stunt. There's a rider in the UK that kills it, named Sparky.
