Hey @Adam L.
What @Herry S. wrote. Going up the hill is easier than going down the hill.
I am living in the beginning of the German Ore Mountains and for hilly area, I recommend the Halfbike 3 because of its break (especially when it is raining).
The 4 gears are also helping you but realistically written, you need some training to climb up a bigger hill - *but* it is doable.
The reward when reaching the upper part of the hill is enjoying the way down.
