I bought a FSIR Spin from China, a 14" micro folder,similar to the Dahon Dove.
It is build around some "rotational" fold. Which makes it stiff and light. Weight is 7kg.
Here some comparison to the Dahon Dove: ·¢¸ö·ç˸14´çºÍ412ttµÄ¶Ô±Èͼ ¡ª 77bike.comµ¥³µ½»Á÷Íø,ÖйúµÚÒ»ÕÛµþ×ÔÐгµÂÛ̳,ÆïÐÐ,´óÐÐ,dahon,p8,p18,bya412,412,·çÐÐfnhon,ÕÛµþ³µÉý¼¶¸Ä ×°

I rode it for some weeks now and so far I am quite happy with it. With its 14" wheels at 82cm wheelbase it's basically a micro folder - but does a decent job at getting you around town (Berlin). Surprisingly quick and nimble. And the frame does not flex at all. I am 185cm tall at 94kg, borderline for this bike, but right in the limits, thanks to the stiffness and 60cm seatpost. The rotational fold is neither intuitive, nor is it compact. But regarding weight and stiffness it is probably the best you can get. Components are a very reasonable choice, but not truly light weight. So there would be still room stripping some weight off (mialo wheel set, lighter crank set, AEST breaks, KMC chain, etc). Mainly I am looking for different handle post with a bit more forward angle giving me slightly more saddle to handlebar room. There seem to be some variations from FNHON available from China.

do you have to remove the seatpost to fold and unfold?

yes, seatpost keeps both parts together, you need to pull it out off the lower frame part to do the rotation. You can then put the seatpost in the lower part (as picted) which gives a slightly more compact fold. Folding time is slightly above a typical side folder, but not much. Around 15 secs. But needs some practice, as it requires very specific hand movement to do it right.

interesting fold. :-) you have a unique folding bike. congratulations. :-)

Edit: mine arrived today. Other than the chain being dry as a bone, I'm really happy with it.

I don't see myself as getting tired from carrying it around when the terrain requires. That's exactly what I wanted.

Nice, do they make something similar but with 16" wheels? I think sourcing 16" tires would be much easier than 14".
