1. A landing gear for an aircraft, the landing gear comprising:
an upper portion configured to be assembled to a structure of the aircraft;
a lower portion provided with first and second axles, a braked wheel being mounted to the first axle, and a motorized wheel being mounted to the second axle;
a strut having an upper end belonging to the upper portion of the landing gear and a lower end belonging to the lower portion of the landing gear;
a main arm pivotally mounted relative to the strut via a pivot connection, said first axle being fixed to the main arm at a distance from the strut, and the second axle being fixedly connected to the strut; and
a main actuator arranged and configured to act on the main arm to move the first axle between a remote position, in which the first axle is remote from the upper portion and a close position, in which the first axle is close to the upper portion,
wherein, in the close position, the braked wheel and the motorized wheel are arranged and configured to be in contact simultaneously against a running surface, and in the remote position, the braked wheel and the motorized wheel are arranged and configured so that the braked wheel is in contact against the running surface while the motorized wheel stays at a distance from the running surface.
