Right bike for the trip

Hi everyone, I’m planning to do a bike trip in Spain (over horse trails, rock gardens and all other terrain not suitable for a gravel bike 🙂 )

I found this cube FS second hand for a decent price, but I’m wondering is this the type of a bike I’m looking for my trip. The bike is XL size , I’m 191cm tall.

I would ride around 50km daily with not much gear on me (food water , some tools).

Is the geometry of this bike to aggressive for a lot of flats and uphill?

Help a fellow rider,

Thanks in advance.
