ummm...
okay kiddies, lets stop being sissies and stay on task.
when i whip. i jump pretty high, lift my knees a little bit, and ONLY use my ankles to kick the deck a little bit and use my arms for the rest of the trick. to make it spin around, you dont move your arms around in a circle, depending on if youre a righty or a lefty, one handgoes up and the other goes down to make your handlebars at about a 60 degree angle or so (im just guesstimating).
then you switch it up. if youre a drummer like me. the motion is a lot like beating the crap out of a tom or a snare with your fists facing forward. apparently that is called an eggbeater. but whatevs
hopefully that made some kind of sense..
