I have a Trek "Navigater 400" I don't know how this varies from the F200 or F400, but I imagine it is pretty much the same. I also have a Raleigh 20 and a Downtube. I generally ride the Trek or DT as I plan to convert the Raliegh to a recumbent folder. and like 8 speeds versus 3 on the 20. I thoroughly enjoy riding both of them, and blindfolded I would be hard pressed to say what I was on. (Or where I was going????) Yes, the steering is lighter on the Trek but as I usually ride a LWB recumbent, I get that "almost wheelie" feeling from any short light folder. My wife is 5' 6 and I am 5' 10'' and it seems to adjust fine for both of us, and my 8 year old grandaughter can adjust it to fit her reasonably well.
For what we use folders for - fold em up and throw em in the back of a small car and drive usually no more than 20 miles at a time when travelling - the little Trek is great, as is the DT and probably the Raleigh 20.
I got my Trek for about $200, an end of the season sale. It's suggested regular price was $650 (maybe that's why it didn't sell) which I think is way too high when compared with other folders like the DT.
Not a bad little bike, though, for what it is intended.............
I can't comment on all the technical details - all I know is that it is a fun little bike, folds nicely, shifts reliably, and while I wouldn't want to try a century on it, it rides pretty good for us.
