I owned a kenevo sl (in s4), and spent a day on a demo levo 4.
And have owned or tried many (many) modern acoustic enduro bikes and e-bikes. Terrain is generally black/double black southwestern alberta and southern bc, canada..
I don't mind the kenevo sl still, it was ahead of it's time. It is behind current times though, a ride on a yeti mte or even a transition relay makes that quite obvious. The longish reach, low stack, f/r ratio, and dropper position are several years behind the curve at this point. Can you still ride one fast ? Sure, but not as easily as more modern stuff.
The levo 4 might be okay for some if you had a more old school technique where you were driving the front end through your hands, but I'm firmly in the "centered" rider position camp. The 435mm chainstays and resulting long front center made it feel sluggish, and required quite a bit of weight shifting around to corner aggressively.
It's a good bike as compared to e-bikes of previous generations, but doesn't hold up well in direct comparison to the most recent crop, in my experience. Of course, that only matters if you directly compare them.
