Segway PT has two primary modes of operation, power assist mode and balance mode.
Power assist mode was designed to help you maneuver the Segway PT when you are not
on the machine. In this mode, the Segway PT's motors are used to assist the user
in moving the unit forward or backward. This motion is controlled by the steering
grip, which becomes a speed control when in power assist mode. This allows you to ascend
or descend stairs more easily and better navigate challenging terrain.
When the Segway PT is in balance mode, a user can safely mount the machine and
begin riding. The display alerts the user which mode the Segway PT is currently in.
