Description

Bicycle Pedals and Cleats {A BICYCLE PEDAL AND CLEAT}

The present invention relates to a bicycle pedal and a pedal cleat, and more particularly, to a bicycle pedal and a cleat which are engaged / disengaged with each other to improve the forward driving force of the pedal.

Recently, among the enthusiasts who enjoy cycling leisure, the bicycle is driven by putting a cleat fixed to the sole of a shoe on a pedal, and many related products have been proposed.
