I just bought a Trek 7.5 FX disc and am happy with it. It's very light. It's similar to a hybrid without a suspension fork. Not quite as comfortable as a hybrid but a lot lighter and easier to pedal. My first bike was a Trek 7200 and I was amazed when I rode the 7.5FX for the first time. It's so much lighter. I now feel that if you want a bike with a suspension fork, buy a mountain bike. I will be selling my 7200 and getting a mountain bike as my second bike.
The tires on my Trek 7.5fx disc don't seem like they'd be good for trails unless they are smooth and hardpacked. If you want to do any off road riding get a mountian bike. They are similar to a fitness bike but have smaller and wider tires and a suspension fork.
