A bicycle pedal which has an upper surface to be engaged by the sole of a shoe of a cyclist and a toe clip for extending around the toe region of the shoe is supported for free rotary movement at all times with respect to a shaft carried by a rotary crank of the bicycle. The pedal is automatically oriented at least when the rotary crank has turned through 90 DEG beyond its top dead center position in an attitude according to which the upper surface of the pedal is substantially horizontal and directed upwardly, this latter orientation in the latter attitude being brought about by way of magnetic means which does not interfere with the free rotation of the pedal with respect to the shaft on which the pedal is supported. |
