1. A transmission having a reduced size, the transmission comprising:
an outer conical pulley;
an inner conical pulley;
a belt, wherein the belt has first and second outward-facing contact surfaces and first and second inward-facing contact surfaces, wherein the belt is in contact with the outer conical pulley via the first and second outward-facing contact surfaces, wherein the belt is in contact with the inner conical pulley via the first and second inward-facing contact surfaces, wherein the belt is capable of sustaining compression forces between the first and second outward-facing contact surfaces, and wherein the belt is capable of sustaining tension forces between the first and second inward-facing contact surfaces;
a first input member; and
a first output member coupled to the first input member via the inner conical pulley such that torque can be transmitted between the first input member and the first output member.
