Claim 8:
9. A vehicle comprising: a chassis;
an engine carried by the chassis;
a gearbox configured for coupling to the engine;
a drive shaft rotatably coupled to the gearbox;
an axle shaft rotatably coupled to the drive shaft; and
a wheel hub carried by the chassis and comprising an epicyclic reducer, a sun gear of the epicyclic reducer being rotatably coupled to the axle shaft:
a housing;
the sun gear contained in the housing that comprises sun teeth and is rotatably coupled to the axle shaft;
a plurality of planetary gears, each comprising planet teeth meshed with some of the sun teeth;
a planetary carrier that couples planetarLgears together and is configured as an output;
a ring gear comprising ring teeth meshed with some of the planet teeth of each of the planetary gears, the ring gear being displaceable within the housing between a reduction position in which the planetary gears are configured to rotate relative to the ring gear and a direct drive position where the ring gear is rotatable locked onto the planetary gears; and
a biaser that acts on the ring gear to propel the latter towards the reduction position.
