Abstract
Abstract The cart is lightweight and portable and may be easily disassembled for transporting from one place to another and easily assembled for use. The cart includes an elongate control frame and a drive frame which is removably connected to the control frame and carries an electric motor and a battery for driving the cart in front of the user so that the cart may be used in pacing the walking speed of the user. The control frame includes a front guide wheel for supporting the front portion of the cart so that it may move along unattended by the user except for changing direction. The two drive wheels may be easily moved to a free wheeling position so that the cart may be easily pushed or pulled by the user in case of battery failure or the like.
