I’ve been knocking about on a Kenevo SL since January. It weighs approx 18kg, and I weigh around 53kg, so if you’re heavier obviously the range you get out of it would be reduced.
I ride with people who have full-fats and they like to run them in a mixture of emtb and turbo modes, which means I’m forced to run mine in Turbo all the time because I don’t have a hope in hell of keeping up with them otherwise!
The best I’ve managed in a single day was 40 miles/65km and 7000ft/2100m of climbing at BPW, using the internal battery and a single range extender. If I was happy/able to run it in eco, the bike would easily manage double that.
If you do get a KSL I recommend trying it as a mullet because it feels like a big old barge of a bike to turn otherwise. Before this I had an Orbea Rise, it was a good bike (until it broke) but it’s not a patch on the KSL in terms of descending capability and general fun factor.
