1. An electric vehicle comprising:
a frame structure including a front cage that at least partially defines an operator cabin and a rear compartment positioned rearward of the front cage in a longitudinal direction;
a plurality of wheels supported by the frame structure;
at least one electric motor supported by the frame structure that is integrated directly into at least one of the plurality of wheels; and
a brake system coupled to each one of the plurality of wheels, wherein each brake system includes
a disc,
a first braking device to contact the disc to resist rotation of one of the plurality of wheels that includes a first housing, and
a second braking device circumferentially spaced from the first braking device about the disc to contact the disc to resist rotation of the one of the plurality of wheels that includes a second housing having a different configuration from the first housing,
wherein the first housing defines a unitary structure that surrounds an open cavity extending axially all the way through the first housing.
