A beach wagon is disclosed which is convertible from a beach-wagon to a table. The wagon is used for transporting goods and contains a large cargo container with an open top. The beach wagon is easily converted from motorized to manual and back again, through the disengagement and re-engagement of the drivetrain. When motorized, a d-c battery-driven motor drives the rear wheels, and the rechargeable battery thereof is optionally aided by a solar panel. Forward gearing includes low-speed for pavement and hard sand and high-speed for soft sand. A rectangular deck has a pair of table leaves hingedly attached thereto and operable between an open and closed position. The leaves form opposite sides of a cargo container and in the closed position form a table. A pair of container panels attach to the table leaves and deck to form the cargo container.
