ABSTRACT:
A device allowing bicycle pedals to take up a steady position when they are not engaged by the cyclist's shoe comprises a knurled ring, formed on the pedal spindle, and a lever pivotally mounted on a pin parallel to the pedal spindle and positioned under the pedal body. The lever has a corresponding knurl at one end for engaging with the knurled ring under the action of a spring means, when the cyclist's shoe is not engaged with the pedal. The knurl is disengaged once the shoe engages the pedal.
