Motors put out their peak torque at zero RPM, but no power at all. Any force times zero distance is zero work.

Golf carts are geared for modest speeds, with high rolling resistance. At highway speeds, the motor would turn too fast and break. A gear set reduces efficiency by a set percentage, plus a small constant, not just a constant. However, it may allow the motor to run more efficiently on average, and increase acceleration too.
