Abstract

This is a pedal and bottom bracket bearing assembly box based on a casing 1 fixed to the frame of a bicycle, specifically in the area of the pedal axle 2 which is coupled to the actual casing 1. There is also a rear shaft 6 provided with a toothing 5. The pedal axle 2 has a set of pinions 3 which transmit its rotary movement to the rear shaft 6 with interposition of an intermediate pinion 4. In addition, an advantageous mechanism has been provided for transmitting the rotary movement of the rear shaft 6 to a conventional plate 17 coupled externally and freely to the pedal axle 2.
