Electric vehicle including an interchangeable cargo and battery submodule

An electric vehicle comprising:

• a reverse tricycle frame comprising:
• a longitudinal tube;
• a steering housing tube coupled to the longitudinal tube and extending vertically from the longitudinal tube;
• a suspension subframe coupled to the longitudinal tube forward of the steering housing tube and configured to suspend the electric vehicle over a pair of forward-mounted wheels;
• a frame-mounted rail interface arranged over the suspension subframe between the pair of forward-mounted wheels;
• and
• a frame-mounted electromechanical interface mounted to the steering housing tube;
• an electric motor configured to drive a rear wheel of the electric vehicle;
• an interchangeable module comprising:
• a module body;
• a cargo compartment integrated with the module body;
• a battery submodule arranged under a floor of the cargo compartment;
• a module-mounted rail interface configured to engage with the frame-mounted rail interface to substantially constrain the interchangeable module in two spatial dimensions;
• and
• a module-mounted electromechanical interface coupled to the module body and configured to:
• engage with the frame-mounted electromechanical interface via translation of the interchangeable module along the frame-mounted rail interface to substantially constrain the interchangeable module in a third spatial dimension;
• and
• electrically couple the battery submodule to the electric motor.
