## Abstract

Exemplary embodiments are directed to a pedal for a bicycle that includes a body, a spindle rotatably secured to the body and for connection with the bicycle, a first magnetic platter non-rotatably secured within the body, and a second magnetic platter rotatably secured within the body and overlaying the first magnetic platter. The first and second magnetic platters each include two magnetic blocks that are separated and magnetically charged by a respective permanent magnet plate positioned therebetween. The second magnetic platter includes a keyed protrusion configured to be engaged by a ferrous metal cleat, which can rotate the second magnetic platter between a first position where the pedal is in a magnetically inactive state and a second position where the pedal is in a magnetically active state magnetically securing the cleat to the second magnetic platter.

## Claims

### Claim 1

A pedal for a bicycle, comprising:
a body;
a spindle assembly rotatably secured to the body and configured to be connected to said bicycle;
a first magnetic platter positioned and non-rotatably secured within the body, the first magnetic platter including a first magnetic block, a second magnetic block, and a first permanent magnet plate positioned between and separating the first and second magnetic blocks, the first permanent magnet plate magnetizing the first magnetic block with a magnetic north polarity and the second magnetic block with a magnetic south polarity; and
a second magnetic platter positioned and rotatably secured within the body overlaying the first magnetic platter, the second magnetic platter comprising a third magnetic block, a fourth magnetic block, a second permanent magnet plate positioned between and separating the third and fourth magnetic blocks, and a keyed protrusion configured to be engaged by a ferrous metal cleat to rotate the second magnetic platter between a first position and a second position, the second permanent magnet plate magnetizing the third magnetic block with a magnetic north polarity and the fourth magnetic block with a magnetic south polarity,
wherein when in the first position the third magnetic block overlays the second magnetic block and the fourth magnetic block overlays the first magnetic block placing the pedal in a magnetically inactive state, and when in the second position the third magnetic block overlays the first magnetic block and the fourth magnetic block overlays the second magnetic block placing the pedal is in a magnetically active state and magnetically securing the cleat to the second magnetic platter.
