摘要： A universal assembly platform for lightweight vehicles including a main vehicle chassis structure, a floorboard disposed over a top of the main vehicle chassis structure. The floorboard defines a floor surface of a lightweight vehicle that is subsequently assembled utilizing the universal assembly platform. The platform additionally includes at least one energy cell reservoir disposed below the floorboard. The at least one energy cell reservoir is structured and operable to retain at least one prime mover energy cell that will provide electrical energy to power an electric motor of the lightweight vehicle subsequently assembled utilizing the universal assembly platform.
