From the bike shop, the 7000's handlebars are slightly above the seat; its saddle is overstuffed.
Not so with the FX series.
However, the 7000 isn't a beach cruiser or English 3-speed "sit up and beg" design, either.
I've been as far as 20 miles in one day on my 7000 (haven't tried anything longer); I've been up to 30 mph on a downhill; I've carried dozens of pounds of equipment and groceries on the rear rack I installed, plus myself.
It's a capable bike. It's not the most efficient or "fastest", but then it's also pretty inexpensive.
If you can afford the FX and like it better, then go with the FX. You should ride both. I did; I liked the FX better; I didn't want to pay that much. I was quite happy to settle for the 7000 because it was such a big step up from anything I'd ever owned up to that point and it was certainly "good enough". Even though I now would like something a little more aggressive, it still is.
