Modules provide the ability of a cleat that couples a shoe to a bicycle pedal to be decoupled via natural lifting motion of the foot upon the occurrence of a specific circumstance such as a tilt of the bicycle indicative of an imminent crash. This allows the rider to use their foot that is no longer coupled to the pedal to potentially eliminate or lessen the crash and / or dismount the bicycle without needing to first perform a cleat release maneuver such as rotating the rear of the foot outward. Shoes may be configured with the module to allow the cleat to decouple from the shoe via the natural lifting motion of the foot in the specific circumstance. Pedals may be configured with the module to allow the cleat to decouple from the pedal via the natural lifting motion of the foot in the specific circumstance.
