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...
