Mine does it too!!! but it is only when the bike is wet after I wash it! When dry, it just dissapears.
It is wind related, but I was not able to identify when it comes from. It is NOT the motor, nor the wheels, it is some kind of aerodynamic noise that is increased with humidity/water on the frame or some other part.
I do not ride the bike wet often, but just a small ride after washing it to help it dry
