Abstract

A hub drive includes an in-hub motor and a shifting in-hub transmission coupled with the motor. A hub drive wheel assembly includes a wheel comprising a hub, an in-hub motor, and a shifting in-hub transmission having an input attached to the motor and an output attached to the wheel. A vehicle includes a chassis, a wheel comprising a hub, an in-hub motor, and a shifting in-hub transmission having an input attached to the motor and an output attached to the wheel for rotating the wheel with respect to the chassis. A method includes providing a shifting transmission and a motor coupled with the transmission in a hub of a wheel, providing electrical power to the motor, and rotating the motor with the electrical power. The method further includes rotating the transmission with the motor and rotating the wheel with the transmission.
