Hey. Month ago bought an mtb, after 150kms noticed it is making grinding/vibrating sound(not the ticking one) while pedaling backwards? Any ideas by the sound of the video what that might be?

sounds a bit like a broken roller bearing. could be in the rear hub or in the buttom bracket. Maybe you can take the wheel off and only rotate the cassette backwards to listen if it still makes the sound.
