Bicycle Pedal Polymer-Metal Platform Segmentation

The pedal body is divided into multiple separable sections (first pedal body section and second pedal body section) that can be assembled together. This segmentation allows each section to be optimized independently - the first section provides structural strength while the second section with its specific geometry provides comfort and grip for the shoe.

Different parts of the pedal body are given different properties - the first pedal body section has a geometry optimized for structural strength and rigidity, while the second pedal body section has a geometry optimized for comfort and grip. This local differentiation resolves the contradiction between overall strength and localized comfort/grip requirements.

The pedal uses a composite construction combining different material properties - rigid materials for structural sections and flexible polymer materials for grip sections. This composite approach allows the grip sections to provide comfort without being prone to cracking, as the flexible polymer absorbs stress better than rigid plastic.

The invention changes the material parameter from rigid plastic to flexible polymer for the grip sections. This parameter change allows the material to deform under force rather than crack, improving reliability while maintaining grip and comfort properties.

The pedal employs composite materials combining lightweight polymers with structural aluminum sections. This composite approach maintains structural strength where needed while using lightweight materials elsewhere, reducing overall pedal weight compared to a solid one-piece aluminum construction.

By segmenting the pedal into separate sections that can be independently manufactured from optimal materials, the design can use lightweight polymers for non-critical sections while reserving aluminum for load-bearing sections, achieving weight reduction without compromising structural integrity.
