Bosch Gen 4 mettalic noise at 15mph

Hi all
Got a weired rubbing noise a bit like disc rub only around 15mph coming from motor. Anyone had similar, happens whether peddling or not. Definitely speed related normal above or below this speed any ideas?

If it happens when you're not pedalling then it's nothing to do with the motor and everything to do with the wheels.

I'd go for some kind of brake disc rub

It's odd it only happens at the same speed will take the rear pads out and give it a spin to try and eliminate the disc rub. Rear wheel on stand is running perfect though with no rubbing at all.
