Great sense of motion, it's perfectly positioned to make it look like the minifig really is flying over the handlebars. Having been in a similar predicament myself once, I can attest to the accuracy of this pose. Ouch.
It's like a clip from 'America's Funniest Home Videos'! Now all he needs is a baseball to the groin! Way to capture the action, I really like how the bike is embedded and he's flying over the handlebars. Been there.~H
