In each level, there are usually obstacles and challenging terrain that may cause the biker to crash and fall off the bike. When this happens, the biker becomes injured and the level must be restarted. A player crashes when they either run into mines, which can be randomly or strategically placed in the levels, or when the head or torso of the biker stick character contacts the ground or a wall. The springy nature of the bike means that this may occur if the bike collides with another object with too much force. In the case of high-impact collisions, the bike may even pass through the surface of the level.
