Abstract

A power assist system for a wagon is provided. The power assist system provides a rotational force to one or more drive wheels under certain conditions to provide propulsion for the wagon. The power assist wagon preferably includes a drive system for providing the rotational force to the drive wheel, a control system for determining when the drive system should be activated and how much propulsion assist to provide to the drive wheel, and a power system for providing power to the drive system. The power assist wagon may also have a safety cut-off system to preclude the drive system from providing a rotational force to the drive wheeleven when the system is in the 'on' mode.
