Abstract
The present invention discloses an electric vehicle frame having a lower portion and an upper portion. The lower portion includes a base and integral sidewalls. The sidewalls extend from the base to form an open cavity. The upper portion detachably joins to the lower portion such that the upper portion covers the cavity and forms a frame assembly which defines an enclosed chamber therein. The strength of the assembly is substantially greater than the strength of each of the portions prior to being joined. The lower and upper portions are formed of cast aluminum. The present invention further includes a method of assembling an electric vehicle, which includes using the frame and a plurality of subassemblies, and the electric vehicle formed therefrom, particularly in the form of a motor scooter.
