[E-Rider]

Just had my first ride on my new Ebike and I've noticed a rubbing every 90 degrees of the crank does anyone know if this is normal.

Whats rubbing what?

I can feel the resistance in the crank every 90 degrees and the sound is coming from the motor even with the power off. When I was riding it sounded like the front disc rubbing. However when I checked its definitely coming from the motor area

Chain guard?

Check the chain device i just had exactly the same problem riding in the mud the chain was picking up crap and lodging it innthe chain device.
Im going to take mine off

I've just been investigating, with the bike on a stand using the walk mode holding the crank still I can clearly hear the rubbing sound so I think this eliminates the crank. I guess the crank is just transmitting the sound

Thank you ill just try that and update you

Fantastic the chain device was just too low hitting the 4 arms that hold the chain ring on.
It sounded far worse like gears grinding. Now I can relax and enjoy the power. Thank you all so much
