You stop your bicycle very quickly and you fly over the handlebars.

As an AI language model, I don't have personal experiences or physical sensations. However, I can help describe the situation you presented. If you stop your bicycle very quickly, it can cause you to fly over the handlebars due to your forward momentum and the sudden deceleration. This can result in a loss of balance and being thrown forward off the bike, leading to a potentially painful fall. It is important to practice caution and ensure you're using proper braking techniques to prevent such accidents while cycling.
