(video) Loud clank PAS brand new BBS02

Hey guys, I need help troubleshooting this to know which parts do I need to replace. Thanks for any help

Do the same video without the pedals spinning, block the pedals from spinning and throttle the motor with wheel up in air. What to do? Personally I'd just buy a hub motor.

Yes, I've abandoned it since. But now, several months later, I need it working to complete another project. So, if anyone have a guess, will be much appreciated. Motor works fine if only throtle is used, but give this loud clank when start pedalling. Thanks.
