Brompton 3ML rattle - only when freewheeling

[Tickmc]

Hi,

I have a used Brompton, shown here:

Unfortunately, there is an odd rattle coming from the backend somewhere and any advice to identify its source would be welcome. It only happens when freewheeling and is silent when pedalling, oddly.

• The rear mudguard has been replaced and fully locked down
• The rear wheel hub has been dismantled and rebuilt
• The 'little' wheels have been taped down

Anyone have any other suggestions I can try?

Keep pedalling. Pretend you are on a fixed-wheel bike.

You're welcome. I'll get me coat.

Does it happen in all three gears?

Mine (6-speed) is noisier when freewheeling in the middle gear than top.

As does my S6L

My 6-speed is noisier freewheeling when I don't put pressure on the handlebars, if I do it goes a lot quieter

Don't stop pedalling!
