The invention claimed is: 1. A transport apparatus comprising: a movable support frame; a plurality of casters to support the support frame; a wheel; a motor operably connected to the wheel and configured to drive the wheel; an external power detector configured to determine if external power is supplied to the transport apparatus and provide a power indication signal in response thereto; an enable input device being operable to receive an enable command from a user and provide an enable signal in response to the enable command; a controller coupled to the external power detector to receive the power indication signal therefrom, the controller configured to drive the motor when the power indication signal indicates external power is not supplied, and a force user input device coupled to the motor, the force user input device (i) being operable to receive a force from a user and provide a force signal based on the force and (ii) including at least one load cell. 2. The transport apparatus of claim 1, wherein the controller is configured to drive the motor in response to the force signal. 3. The transport apparatus of claim 1, further comprising at least one handle operably coupled to the force user input device, the at least one handle configured to receive the force from the user. 4. The transport apparatus of claim 1, further comprising a first handle and a second handle spaced from the first handle, wherein at least one of the first handle and second handle is configured to receive the force from the user. 5. The transport apparatus of claim 4, wherein the first handle and the second handle are supported for selective pivotal movement such that the first handle and the second handle are configured to fold towards each other. 6. A patient support, comprising: a support frame, including a plurality of wheels to move the support frame along a floor; an external power input, coupled to the patient support, to provide an external power to the patient support; a traction device, coupled to the support frame, the traction device including a storage position spaced from the floor and a use position to contact the floor; an external power detector, coupled to the external power input, configured to generate an external power signal if the external power is supplied to the external power input; a controller, coupled to the external power detector, to receive the external power signal, the controller configured to enable movement of the traction device to the use position, upon receipt of the external power signal; a motor, coupled to the traction device, to drive the traction device for powered movement of the patient support; and a force user input device coupled to the motor, the force user input device being operable to receive a force from a user and provide a force signal based on the force. 7. The patient support of claim 6, wherein the controller is adapted to disable movement of the traction device from the storage position to the use position in that absence of the external power signal. 8. A patient support, comprising: a support frame, including a plurality of wheels to move the support frame along a floor; an external power input, coupled to the patient support, to provide an external power to the patient support; a traction device, coupled to the support frame, the traction device including a storage position spaced from the floor and a use position to contact the floor; an external power detector, coupled to the external power input, configured to generate an external power signal if the external power is supplied to the external power input; and a controller, coupled to the external power detector, to receive the external power signal, the controller configured to enable movement of the traction device to the use position, upon receipt of the external power signal, wherein the controller is adapted to disable movement of the traction device from the storage position to the use position in the absence of the external power signal, and further comprising a wheel mode detector coupled to the controller, configured to generate a steer mode signal upon placing the wheels in a steer mode. 9. The patient support of claim 8, wherein the controller is adapted to disable movement of the traction device from the storage position to the use position in the absence of the steer mode signal. 10. The patient support of claim 6, wherein the controller is configured to drive the motor in response to the force signal. 11. The patient support of claim 6, wherein the force user input device includes at least one load cell. 12. The patient support of claim 6, further comprising at least one handle operably coupled to the force user input device, the at least one handle configured to receive the force from the user. 13. The patient support of claim 6, further comprising a first handle and a second handle spaced from the first handle, wherein at least one of the first handle and second handle is configured to receive the force from the user. 14. The patient support of claim 13, wherein the first handle and the second handle are supported for selective pivotal movement such that the first handle and the second handle are configured to fold towards each other. 15. The patient support of claim 10, further comprising a motor drive, coupled to the motor, adapted to drive the motor. 16. The patient support of claim 15, further comprising a user enable device, coupled to the motor drive, the user enable device configured to generate an enable signal to enable the motor drive to respond to a speed control signal.
