Abstract
In one embodiment, the invention is a frame for a ride-on vehicle having at least one front wheel, at least one rear wheel, and a plurality of substantially similar battery packs. The frame defines a central plane and includes a front end located adjacent to the front wheel(s), a rear end located adjacent to the rear wheel(s), and a lattice structure that extends substantially between the front end and the rear end. The lattice structure includes a first portion that includes battery pack mounts that secure a first subset of the battery packs arranged in two layers, and includes a second portion that includes battery pack mounts that secure a second subset of the batter packs arranged in a single layer. The lattice structure also defines a truss that mechanically couples the front wheel(s) to the rear wheel(s).
