Abstract: In colliding with a step, the front wheel of the bicycle may roll up the step or spring back to the ground. In the latter case, a rollover or a dumping accident may happen. In this study, a general collision model based on the coefficient of the restitution (COR) is built.The safe ranges of the wheel speed and the velocity direction are obtained. Besides, the influence of the step height is also discussed.

Key words: collision model|coefficient of restitution
