A hand-driven wheeled cart or suitcase, including: a body section of the cart or suitcase including a back side, a top side, a bottom side and a front side; a handle coupled to the body section; two wheels coupled to the bottom side of the body section, adjacent the back side of the body section; and a motor housed in one of the two wheels, the motor being actuated by a button on the handle.

A container for holding and transporting goods is provided. The container includes a base and a plurality of walls connected to and extending upwardly from the base to a brim to define an opening for receiving the goods. A pair of lock-lugs extend from the brim. The container also includes a handle defining a pair of lock-keys for receiving the lock-lugs and pivotally connecting the handle to the brim for pivoting between a storage position and a raised position. The lock-keys interact with the lock-lugs to establish a locked condition of the handle when the handle is in the raised position and pulled upwardly away from the base for allowing a user to pull the container across the floor with the handle and an unlocked condition where the handle is pushed downwardly when in the raised position to allow the handle to be rotated to the storage position.
