The 6.5" hub motor wheel is a hoverboard wheel with a built-in electric motor. It is what propels and brakes the hoverboard.
- Replace it if the tire or rim is damaged, if it seizes, makes unusual noises, has broken wires, or if the sensors inside the motor fail.
- Compare the diameter, wire connectors, and axle mounting with the old wheel.
After replacing it, calibrate the hoverboard following the instructions for your model.
