摘要

A three-speed gearbox for mopeds, with built-in pedal start and foot speed selector, essentially characterized by the fact that the fork that moves the intermediate pinions has been equipped with a ratchet system consisting of a ball which, under the action of a spring, is housed in the slots conveniently made in the axis of the fork of the gear change, achieving that said fork remains fixed in its correct position, with respect to the speed chosen with the pedal of the selector.
