You know.. humping, like thrusting your pelvis back and forth?

-to start it, just pull on the bars while leaning way back.
-once the front tire is in the air, pull it up towards your body a bit to bring it up higher.

-if you start to feel like you are about to flip over backwards, bend your knees and thrust your hips forwards

-if you start to fall back down forwards, straighten your legs and get your ass as far back as you can.

You WILL loop out many times while learning, so get used to jumping off and running behind the bike.
..try not to grab the brake though, its bad form.
