Does anyone out there who has a late model Ultra Fat hear any noise from the motor when under power and pedaling. I have the new All Terrain Ultra Fat and hear a hard to describe sound (like light sandpaper on metal) while pedaling in any PAS mode. The sound is definitely coming from the motor and stops if I turn the motor off even if I keep pedaling. The sound is not real loud but you can hear it easily. Since I am not familiar with mid drive motor noises I do not know if this is normal. I also have a newer 750 watt rear hub motor bike and that motor is silent.
