Abstract: A motorized cart, including: a collapsible frame with a collapsible storage compartment, a front wheel, and two rear wheels rotating about a single axis. The frame has a folding support platform including hingedly connected first and second portions. The first portion rotatably connects at a front of the frame, and the second portion rotatably connects to a rear of the frame. A drive compartment houses a battery, a drive controller, and a motor for driving a rear wheel, and is positioned on the frame to position the battery, the drive controller, and the motor below and forward of the axis in an expanded, upright mode, thereby positioning a cart center of gravity forward of the axis.

Abstract: A motorized cart, including: a collapsible frame; a handle and a collapsible storage compartment connected to the frame; and at least three wheels, including a front wheel and two rear wheels disposed at a rear of the frame for rotating about a single axis. The cart also includes a drive compartment housing a battery, a drive controller, and at least one motor electrically connected to the battery and the drive controller for driving at least one of the rear wheels. The drive compartment is positioned on the frame to position the battery, the drive controller, and the motor below and forward of the rear wheel rotation axis when the cart is in an expanded, upright mode, thereby positioning a center of gravity of the cart forward of the rear wheel rotation axis to enhance stability.
