Videos of the issue
Any advice appreciated. We are about $800 into service and parts replacement trying to eliminate this unenjoyable noise.
It starts around mile 4 and gets progressively worse as the miles add up. Before the bike shop, pedals and seat tubes regreased. Bike shop replaced both bottom brackets, the essentric the chains, and just replaced the rear crankset. They cleaned the headset. They thought maybe the PAS disc was rubbing on the bottom bracket, I removed and the noise continues.
It's when I'm pedaling in front. If she comes off the pedals the sound goes away. I've also swapped out the pedals with another bike with no joy.
