The present invention is a pre-commercialization prototype of a novel, compact in-wheel motor system designed around the existing suspension and braking system of a conventional vehicle. The in-wheel motor is intended to be retrofitted to non-hybrid vehicles to convert them into split-parallel hybrid electric vehicles. The motors compact packaging inside the vehicles rear wheels, the halbach array rotor, enhances the motor power output. The present invention can also be used in a flat chassis neighbourhood electric vehicle and allows better packaging since the motors are mounted inside the wheels.
