1. An electric vehicle comprising:
a frame structure;
a plurality of wheels supported by the frame structure;
at least one electric motor supported by the frame structure; and
a brake system coupled to each one of the plurality of wheels,
wherein:
each brake system includes a disc and a first braking device to contact the disc to resist rotation of one of the plurality of wheels that includes a first housing,
the first housing defines a unitary structure that surrounds an open cavity extending axially all the way through the first housing, and
the open cavity is radially offset from a central rotational axis of the disc.
