title: iPhone - Bike physics game
body: <p>I want to make a game where you ride a bicycle down a hill - using accelerometer for rider tilt and a pedal/brake button (vaguely like Moto X Meyhem).</p>
  
  <p>Does any one have any ideas where i can find tutorials/documentation of the things that i would have to do. (don't know where to start)</p>
  
  <p>I guess what i need is: To simulate physics of the bike (inertia &amp; tilt of rider), figure out how the bike interacts with the terrain (ie friction &amp; acceleration), and how to store the information of the actual surface of the terrain.</p>
  
  <p>Could i use Cocos2d and Chipmunk? Any pointers, ideas, suggestions? Any help is appreciated and thanks very much in advanced.</p>
