A false assumption would be that an alu bike frame crack is easy to repair.
I have a Alu AC Tig welder at home, I"m a more than decent welder.
Filling up such crack by welding is easy, but aspects like the preparation, cleaning, grinding, inspection, weakening by over-rigidizing, QC, tests...

That Ergon looks a bit like our Venec saddle, but longer.
Can you do a side-to-side comparison with some images ?
Well then don't care about the battery.
You'll drive further with a 500wh or 625wh battery than me with my 725Wh battery.
You are inbetween S and M, for Cube better choose the bigger bike.
The non-750Wh ebikes still have the 2020 frame wit bent top tube.
If you go for the 625Wh, have a look at...
A nice Article, from a Downhill-Enduro-Bikepark point of view. (that could be the market the 160S is made for)
For +80kg Trail-Enduro-XC (like me) or Commuting-Gravel (like treadstarter) this is completely different.
I had 4% left on the battery after a 65km Enduro ride, and at the finish talked...
If you are not too big and therefor prefer/like/accept 27.5 wheels (like me), absolutely go for it !
For commuting, you just have to put tyres with much lower rolling resistance.
You could eventually put the rear DHR to the front, and an Ikon/Rekon/Forekaster at the rear
Or Pirelli Scorpion...
That's already a lot better with the Patina !
Maybe with some detergent or thinner, the yellow peels off and the white stays.
Preferably a product that doesn't eat the tyre afterwards :)
If you're below 30 you can go for the hardtail, even 500wh is OK.
If you're above 50 you will need the full suspension, 750wh and maybe a spare battery and a softer saddle :)
Some parts from BikeInn/TradeInn.
My least preferred shop since I once lost myself in their Robotized Whatsapp "service"
But the only webshop that has the post lever and the caliper available for a normal price.
I already have the matte brake lever, tube, fluid and bleed kit,
everything is...
