I must admit that fat tyred bikes aren't my thing either. There is a lad who has a YouTube channel, that uses one for wild camping exploits, and it was the study rear rack, and front headstock bolt on rack mounting points that caught my attention. I also wanted a bike that I could work on in the event of motor/electrical failure. The price was okay as well.
I don't actually like the fat tyres, and the bike about 10kg heavier than I would have liked.
I have never understood the one size frame fits all idea either. At 5'10" tall I still manage to find the crossbar too high.
On the plus side with the bike, it is pretty utilitarian and functional, although the front forks are pretty twitchy when the bike is loaded. The brakes also aren't the best either, but somehow it all works.
