A bicycle pedal, comprising a pedal shaft (10) for coupling to a crank (3) of a bicycle, a platform (4) for supporting a foot of a bicyclist. A hinge assembly (7) is provided that connects the platform (4) to the pedal shaft (10) so as to be rotatable about a pedal shaft axis extending transversely to the crank (3) of the bicycle, a longitudinal axis perpendicular to the pedal shaft axis and a top axis perpendicular to both the pedal shaft axis and the longitudinal axis. The hinge assembly (7) includes a ball hinge (8) having an inner bearing surface coupled to the pedal shaft (2) and an outer bearing surface that is rotatably supported on the inner bearing surface and that is coupled to the platform (4). The inner and outer bearing surfaces are concentric sphere surfaces, and the center of rotation of the spheres lies on the pedal shaft axis. |
