1. A vehicle wheel with an in-wheel motor, comprising:
a vehicle wheel comprising a hole with an inner circumference; a motor installed inside the hole of the vehicle wheel, the motor comprising a stator and a rotor; the rotor comprising a ring shape and rotatable about an axis; the stator comprising a first arcuate stator block and a second arcuate stator block; and a motor housing comprising a first rotor segment, a first stator segment, a second rotor segment and a second stator segment arranged in order along an angular direction about the axis such that the first and second stator segments are opposingly arranged about the axis, wherein the first stator segment houses the first arcuate stator block and the second stator segment houses the second stator block such that the first and second arcuate stator blocks are opposingly arranged about the axis, wherein the first and second rotor segments radially smaller than the first and second stator segments such that the motor housing provides:
a first space that is that radially beyond the first rotor segment and angularly between the first and second stator segment, anda second space that is radially beyond the second rotor segment and angularly between the first and second stator segments.
