Hi all, I’m looking for some help please, a friend and Brompton owner offered to replace a flat tyre on the rear tyre, alas when I took it out the chain looks like it’s not on the gears properly, does anyone know how to fix this please?

Literally just lift it back onto the cog that should be all you need to do.
it looks like the chain tensioner isn’t located properly, making the chain basically loose all over the place. u have to place the chain back on the smallest cog and on the front chainring, and push the chain tensioner to the front, towards the cockpit / handlebar. then slid the chain onto the jockey wheels and when it is properly tensioned, the chain will stay on its place.
if this instruction isn’t clear, please go to Youtube with keyword Brompton tube / tire change.
Thanks, I managed to get it back onto the cog, pretty daft really but I appreciate your help
Please clean your drivetrain… it’s giving me anxiety!
Half an hour with degreaser, a couple of old toothbrushes and microfibre cloths, rinse well (don’t use a pressure water; poured out of a watering can is fine), dry off, then re-lube with a drop on each link. Run it through, then wipe off excess lube.
