Maybe it was matter of saddle?
The saddle on FX3 is pretty stiff and after first couple of rides I was thinking about changing it. Eventually I actually liked it - as while cycling initially it felt too hard, after those couple of rides my bum didn't feel sore or anything. And it always felt sore on my previous bikes if I rode them after some break.
As more than 90% of my cycling is on a hard surface (asphalt or concrete) I don't feel like changing the tires. I'm 6'3" and my saddle is more-less on a same height as the handlebar (the bike is in XL size) - anyway the position feels great for me. I've tried Giant Escape 1 before buying bike and Trek felt much more comfortable.
On the other hand, I live in Ireland and there are only electric versions of Trek Verve available here, so didn't even bother to try it out.
