looks good - never seen any for sale in UK or continental Europe

I think you can get them in the Netherlands...

Initial impressions
The FSIR is my first single-tube, navel-fold, mast handlepost, tall seatpost folding bike, so it is a bit of novelty to me. I have to say, though, it's quite decent, quite good in fact. There is no flex, play or give anywhere. The thing is solid. I've loaded it up, and it still rides great. The cockpit is a little smaller that what i am accustomed to, but it's fine. A forward sloping handlepost could take care of that easily. Not bad, not bad at all. Under $600, it may be a top pick for affordable, no non-sense 406-wheel folder. I may yet pick up another one for the wife...

I'm interesting in the Solorock Spin 5 (which looks like the same frame) as a travel bike, since it looks like the frame should come apart easily at the pivot. Have you tried this, and if so does it pack down fairly small when separated?

interesting idea. but, no, i have not tried it yet.

It becomes a very small package if you take off the fork, which is easy, quick and clean since the headset has capsuled industrial bearings (..on my bikes) and the wheels additionaly. I didnt travel with my Spin 5.1 yet, but with my 2.0 (14" wheels). It fits into carry-on baggage.

Nicely done. Did you weigh it before you stripped it?

I completed a 900km tour of Korea on the FSIR. No mechanical issues or problems to report.

No, I did not, but they come under 10kg right out of the box. Mine comes in at 9.5kg sans any specifically light components.
