Does the noise persist even when the motor is spinning under no load? I.e. when free spinning in mid air? If so, please verify that there is nothing rubbing against the wheel (such as mudguards, brake or derailleur cables, misaligned disc-brakes etc).
If this is not the case either, then the fault is most likely to be with the motor. This needs to be sent back to us for repair/replacement.
