a plurality of k gears between a first gear referred to as gear No. 1 and a top gear as gear k;
a series of k input pinions arranged so as to turn freely around a selection shaft with an axis X2, said selection shaft accommodating a worm screw and a shuttle;
a series of k output pinions with an axis X3 that rotate conjointly with a hollow shaft being arranged so as to surround an axis of a crankset of the mobility machine; and
a gear shift actuator arranged so as to displace the shuttle along the worm screw between a plurality of k positions and to engage a selected gear.
