Just speculation on my part but looks like someone ordered the wrong options and now wants to sell it.
Two speed with a low ratio doesn't make sense unless it's just for a very hilly area or taking it easy and going for a slow leisurely ride. I don't know why anyone would get a Brompton with 2 speeds when the 3 speed costs the same and is less complicated.
Also low 'S' handlebar with an extra long seat post wouldn't suit everyone.
If he/she was asking less for it, then it would be worth it, to get higher handle bars (tall person) or the shorter seat post (regular height person). Also to get the 2-to-6 speed conversion kit.
