Hello everyone!
My Brompton's indicator chain is broken and the chain dropped out during my riding.
Currently, the internal gear is malfunction, I cannot shift it by the lever.
Anyone have experience for this problem?
Many Thanks!

Can you detach the link (unscrew it) and reattach all the parts?
Keep your bike in middle gear to get the tension back then you set it up. There’s videos from Brompton about jiggling this part back in.
I’m assuming there’s no actual mechanical failure, but I think all the parts you’re showing are replaceable.
That chains still connected it’s not broken what’s happened is your bolt has come undone. You need to undo the indicator chain from the adjuster and the hub. Re-attach the bolt holding the chain tensioner on and then reset the gears following the video below.

Looks to me like the lock nut that the indicator chain goes through just came unscrewed. Watch a video on how to remove and reattach the rear wheel and it will cover how to reinstall the chain tensioner including a he part you are seeing here.
