A motor assembly for a transport vehicle (such as a skateboard) having at least one wheel for rotating about a shaft having an end distal to the wheel and an end proximal to the wheel, the motor assembly comprising a stator fixed to the shaft, and a motor bell surrounding the shaft at the location of the stator, wherein the motor bell comprises a first end being adapted to be attached to the wheel for transferring rotational movement of the motor bell to the wheel, and a second end surrounding the shaft at the location of the end distal to the wheel, wherein the second end of the motor bell is a free end permitting removal of the motor bell during removal of the wheel. The motor bell being adapted to permit airflow therethrough for cooling of the motor assembly.

Fender assemblies are disclosed, each including a rectangular frame defining a central aperture. The perimeter of the central aperture may have a rounded-rectangle shape. A fender arch in the form of an arcuate sheet, e.g., of carbon fiber (CF), terminates on either end at respective first and second flanges extending outward to form a planar base. The arcuate sheet extends through the central aperture to reach above a top side of the frame and the flanges abut a bottom side of the frame. A mud guard is coupled to the rectangular frame through the first flange of the arcuate sheet, such that the mud guard extends from the first flange away from the second side of the frame. The frame and mud guard may be made of plastic, and may be configured to absorb assembly forces to avoid damaging the CF fender arch.

Disclosed is a power-driven shoe. The shoe includes a shoe sole having a plurality of rotatable wheels arranged below the shoe sole in an overlapping fashion. The distance between the rotational axis of the wheels is less than or equal to the diameter of the wheel, such that vertical obstacles can be overcome in both the positive and negative displacement directions for increased ground stability. The shoe sole includes a toe part and a sole part that are connected to each other, via a hinge, in both a rotational and translational configuration, such that at least one front wheel or at least one middle wheel are independently in contact with the ground while maintaining at least one rear wheel in contact with the ground throughout a bi-pedal gait cycle, allowing for comfort during a user's natural range of motion.
