What type of crash can a hard front brake application cause?

Applying the front brake hard can lead to an endo or over-the-handlebar crash due to the mechanics of how bicycles operate. When a cyclist engages the front brake with significant force, the bike’s weight shifts forward, transferring more weight onto the front wheel. If this transfer is abrupt or excessive, it can cause the rear wheel to lift off the ground. As the rear wheel comes up, the rider can be thrown over the handlebars, resulting in an endo. This type of crash is particularly hazardous as it can lead to serious injuries if the rider is not able to balance themselves or if they land improperly upon falling.

Understanding this dynamic is crucial for cyclists, especially those in public safety roles, as it highlights the importance of proper braking techniques and bike handling skills to prevent such crashes.
