For example, as shown in FIG. 12 , the cleat 14 may be compressed against the first cleat securing member 24 to cause the second leg 32 c to deflect and cause the pedal body 22 to pivot relative to the step body 28 . The second leg portion 32c is pushed by the protrusion 22a in a circumferential direction relative to the axis R1 to generate a spring force relative to the protrusion 22a in the circumferential direction. The first leg 32b is held by the protrusion 28c at the same position as the neutral rest position. Additionally, for example, as shown in FIG. 16 , cleats 14 may be compressed against second cleat securing member 26 to cause first leg 32 b to deflect and cause pedal body 22 to pivot relative to step body 28 . The first leg 32b is pushed by the protrusion 22a in a circumferential direction relative to the axis R1 to generate a spring force relative to the protrusion 22a in the circumferential direction. The second leg 32c is held by the protrusion 28c in the same position as the neutral rest position. These spring forces serve to return the pedal body 22 to a neutral rest position relative to the pedal body 28 .

In the illustrated embodiment, the bicycle pedal 12 is a double-sided bicycle pedal, which means that the cleats 14 can be releasably secured to either side of the bicycle pedal 12 .
