Abstract
A vehicle frame has first and second members having adjustably telescoping channel portions securable by bolts disposed in selected combinations of holes provided in the channel portions for providing a total vehicle frame of a chosen length and wheelbase. Adjacent portions of the respective members define portions of a battery compartment which varies with the size of the vehicle frame to accommodate the power requirements thereof. Channel shaped spacers join facing portions of the members for increased strength of the resulting frame.
A rear axle mounting assembly is adjustably mounted on the rear member for independent adjustment of the wheelbase.
A second embodiment has front and rear members secured by a selected nestable spacer member having an adjustable axle mounting for independent adjustment of the vehicle frame and wheelbase.
