SC Bullit knocking/rattle

[shadowfacts]

I rode about 1,000 miles on my bullit with a new ep8 motor before this noise started. I never realized how quiet my bike was until it started making this noise when I'm riding downhill. It's driving me insane.

Is this the dreaded ep8 motor rattle? Is there anything else I should check?

Here's a youtube short that shows how loud the knocking is:

Sounds like the forks are loose in the frame (loose headset).

Yep, it sounds like that, but I've checked that already

It is well tensioned / no play

Y'all are gonna laugh at me. I figured out the noise.

The airtag that I had stuck to the inside of the frame had broken loose from its VHB tape. It was rattling around in the bottom of the downtube, next to the motor. At least that was an easy fix.

To ensure they never came loose used high density foam and cable ties to fasten Chipolo ONE Points inside our Rail downtubes.
