1. A complex planetary assembly, comprising:
an input and an output;
a ring gear;
a first stage planetary assembly comprising:
a first sun gear;
a first carrier comprising a front face and a first plurality of pins extending from the first face;
a first plurality of planet gears, each of the first plurality of planet gears being rotatably coupled to one of the first plurality of pins on the first carrier; and
a second stage planetary assembly comprising:
a second sun gear;
a second carrier comprising a front face and a second plurality of pins extending therefrom;
a second plurality of planet gears, each of the second plurality of planet gears being rotatably coupled to one of the second plurality of pins on the second carrier;
wherein, at each of the second plurality of pins on the second carrier, at least two planet gears of the second plurality of planet gears are coupled thereto;
wherein, the at least two planet gears of the second plurality of planet gears are coaxially arranged adjacent to one another.
