Hi. My P Line makes a creaking sound with each pedal rotation. Tried to capture in the attached video. After a while it tends to stop or at least becomes less noticeable. Any suggestions as to what it is what might need some adjustment.
Thanks!

Chain probably needs some lubricating: [https://global.brompton.com/support/knowledge/lubricating-your-brompton-chain](https://global.brompton.com/support/knowledge/lubricating-your-brompton-chain)
Suspension block. Disassemble it and grease all touching surfaces, especially the surface of the bolt (so not put grease on the thread!)
Also check the rear triangle hinge.
it’s one of these two:
– the rear triangle pins need some lube https://youtu.be/N9FAzzcQtRM?si=rWmLl4FfHLJ3h_sn
– some lube on the crank, might just be dirty
my bet is on the first one
I had a creak like this I couldn’t identify for a couple of years. Didn’t always have it and as your video shows, it only comes on as the crank is in a particular position, which made it hard to identify and couldn’t find any solution. One day (very recently) I realised I was overtightening the frame clamp. I don’t do it as tight now. Noise gone.
