It seems that Fnhon will sell a 20" Brompton clone with disc brakes. As fr as I know, its the first time that Fnhon makes a Brompton clone and its also a complete bike, unusual for Fnhon !?

If the frame quality is similar to the quality of the Fnhon bi-fold frames, it should be a good deal.

The transmission with a nice cassette and derailleur seems also good, I suppose that this derailleur also ensure the chain tensionning when the rear triangle is folded like done with a L-twoo Fold B derailleur?
