Abstract
A wheel pack assembly includes a pack portion wearable by a user, a wheeled portion removably coupled to the pack portion, and a power assist system. The pack portion includes a first interfit element. The wheeled portion includes a frame, a second interfit element coupled to frame and configured to removably couple with the first interfit element of the pack portion, and a first wheel set coupled to the frame and disposed at a location spaced apart from a rear end of the wheeled portion. The power assist system includes a motor mechanically coupled to the first wheel set, at least one sensor coupled to the at least one of the first interfit element and the second interfit element, and a controller configured to operate the motor based on feedback from the at least one sensor.
