This game is a very complex bike game. The point is to upgrade your bike as much as possible and then win all the racers you can. Dont try to learn what all the buttons do because that's not the point. Just pedal to the metal and hope for the best. In time you will learn to tune the bike as good as possible. Consider to save the game from time to time beacause there's no guarantee that the bike game will look the same after you close the window and re-open it.
