Hi there!

Short story: I always owned Trek bikes. From the 3500, to the 3700 and lastly i own a 3900 Disc. They are very durable and have very good pieces. Also i never tried other brands.
I use it the most part of the time in the city. Work to House. And now i'm searching something more lightweight and fast. I saw that there's two Hybrid models that caught my attention but i don't know which one to choose.
In addition to moving around the city I would like to make some trails at the weekend. So I would like the bike to be versatile in that sense.

On one side there's the Trek FX family. I'm between the FX2 and FX3. (The difference is that the FX3 have carbon fork)

Is lightweight
Doesn't have suspension
Narrow tires.

On the other side there's the Trek DS family. Specifically the DS2.

A little bit heavier
More all around tires
front suspension

So which one should be the better option? Any suggestions?

Thanks in advance!

Depends on the trails--I don't like my FX3 on anything but really packed dirt or paved. On pavement, it's great, but there's no mistaking it for a mountain bike on single track.

Livedarklions gave excellent advice.

When I sold bikes for a living and someone came to me with this dilemma I would ask one question "what are you going to be doing with your bike most of the time?" If 80% of your riding is commuting, then the FX is the way to go.

There are other solutions to your problem but I will stick with the one question you asked.

Thanks to both.
So if i my ridding is 80% commuting. The FX is way better than the DS?

I only know the FX, I've never ridden the DS, but I think the FX is going to be way more fun on a road than the DS, and I've ridden my FX3 with a pretty fully laden rear rack, so I think it would be just fine for commuting. You get better components on the FX3 than the DS3 because I think they skimp on the DS a little bit to compensate for the cost of the suspension.

The answer may also depend on what that other 20% is. The FX3 definitely sucks on rocks, the DS might be a bit better there, but the FX3 is really more of a flat bar road bike. BTW, I can go quite fast on my FX3, doubt I could on the DS.

You don’t need suspension on the road, even for commuting. So unless the gravel/off-road you’d like to do is more than just basic hardpack road and more like single track, the suspension is not necessary. So the FX will be a significantly better and likely more enjoyable bike for the riding you’ll likely be doing more often. It also meets your stated wants of something faster. Basic common sense says the FX is a better choice. if you plan on doing some more serious off-road use, or would like to move into that arena in the future, you would be better served with an MTB/downhill rig, or at the very least a more proper non suspension ‘all road’ rig. You’re always going to do more of one kind of riding than others, so when you’re considering a bike purchase, always let that main use be the biggest deciding factor in your equation and go from there, especially if you’re trying to purchase a ‘do everything’ kind of bike, which realistically doesn’t exist because compromises will always be there and very apparent in certain situations.
