Decoupling of a shoe from a bicycle pedal

A shoe comprising:

• a shoe sole;
• a foot retention structure coupled to the shoe sole to retain a foot of a rider upon the shoe sole;
• a module affixed to the shoe sole, the module comprising:
• a coupling mechanism configured to couple to a cleat that is configured to be retained by a catch of a bicycle pedal to couple the shoe to the bicycle pedal;
• a detection mechanism that detects a tilt at the module;
• a comparison mechanism that compares the detected tilt to a threshold;
• and
• a release mechanism that has a locked state to prevent decoupling of the cleat from the shoe, that has an unlocked state, and that becomes unlocked while the detected tilt exceeds the threshold so that the unlocked release mechanism allows decoupling of the cleat from the shoe to allow decoupling of the shoe from the pedal.

A module for providing a coupling between a shoe and a pedal, comprising:

• a coupling mechanism configured to couple to a cleat that is configured to be retained by a catch of a bicycle pedal to couple the shoe to the bicycle pedal;
• a detection mechanism configured detect a tilt at the shoe;
• a comparison mechanism configured to compare the detected tilt to a threshold;
• and
• a release mechanism that has a locked state to prevent decoupling of the cleat from the shoe, that has an unlocked state, and that becomes unlocked while the detected tilt exceeds the threshold so that the unlocked release mechanism allows decoupling of the cleat from the shoe to allow decoupling of the shoe from the pedal.

A pedal for a bicycle, comprising:

• a base configured to be coupled to a crank of the bicycle;
• a catch configured to couple to a cleat of a shoe;
• a module affixed to the base, the module comprising:
• a coupling mechanism configured to couple the catch to the base;
• a detection mechanism that detects a tilt at the base;
• a comparison mechanism that compares the detected tilt to a threshold;
• and
• a release mechanism that is affixed to the base, that has a locked state to prevent decoupling of the catch from the base, that has an unlocked state, and that becomes unlocked while the detected tilt exceeds the threshold so that the unlocked release mechanism allows decoupling of the catch from the base to allow decoupling of the shoe from the pedal.
