New P Line owner here. Barely ridden on this beauty but I realised that when I pedal (in gear 1), the chain rides over the rear sprocket and makes a clicking noise. Is this normal or is the chain tension too low? How can I fix it?

Does it happen if you move it slowly? I think I had something like that and it was one of the cogs teeth was out of shape so was pushing it away. I think. I took it back to the shop and they fixed it.
Too much cable tension
I think you need to loosen the upper limit screw of your derailleur. I am not sure how it’s done on the new Brompton derailleur, but it’s most probably with the two screws you see in the derailleur arm. It’s a very simple procedure, take a look at this video and you’ll understand what I’m talking about: https://m.youtube.com/watch?v=UkZxPIZ1ngY
