Yup, I’ve already tightened all that including putting a pad and Velcro strap on the battery cover. It could be motor cover rattle as mine gets very loose in a side to side movement. To me tho it sounds exactly like my old gen 4 on my whyte e160.Check the battery compartment is screwed in tight.
You have to take the battery lock out to gain access to the hex bolt that holds the battery part in. See if that's loose.
Mine was rattling and when I looked down my battery was hanging out!
