Unbelievable how he can reverse the inertia to pull that one off.

I completely do not get the mechanics of that whole thing.

 
I think the key is that the way he is transferring his body's motion
forward to the bars while the front tire is off the ramp and the rear
tire is still on the ramp. Then the rear suspension rebound (which
looks like it starts while the rear tire is still on the ramp, and can
do so because he has unweighted the rear of the bike) and the shape of
the ramp kick the rear tire up a bit.

Wouldn't be surprised if he gives the rear brake a quick stab after
the front wheel leaves the ramp- it sure looks like the tire is
spinning too slowly for his speed.

I think he is also using his body position/motion to gain as little
upward motion in his body as possible.

A no-brainer is applying front and rear brakes while in the air, both
front and rear wheel momentum will aid the forwards rotation. The
front wheel isn't rotating while he's in the air.

 fill tires with cement then hit brake at crest of hill,
or not.....
