    It depends how realistic you want to get. Like if you drive off a ramp, should the bike stay airborne for a couple of seconds? Should it behave like this game? http://www.miniclip.com/games/trial-bike/en/

    If so, the math is probably very complicated. Rather than reinvent the wheel, you should use a physics engine like Box2D http://box2dflash.sourceforge.net/ Download the file, pick one of their demos and customize it to fit your needs.

    If you're doing something simpler (the ground is smooth; the bike never leaves the ground) then you could probably get away with something simpler.
