Patent attributes
An example vehicle includes a battery tray that is movably coupled to a front axle assembly of the vehicle. A back end of the tray is coupled to a first chassis member and a second chassis member of the vehicle via respective joints that allow rotational motion of the tray with respect to the first chassis member and the second chassis member. The vehicle's chassis includes a first rail comprising a first plurality of holes and a second rail comprising a second plurality of holes. The first rail slides within the second rail to provide an adjustable wheel-base length or width for various configurations of the vehicle. When the first plurality of holes and the second plurality of holes are aligned, one or more fasteners may be used to secure the first rail to the second rail to select a particular wheel-base length or width.
