Back in the day, I used to have a 360 Montesa that I used to ride enduros with. All my riding had been on road up to that point. What I quickly discovered was how tiring it was. Anyway, fast forward 35 years and I was on YouTube watching Isle of Man TT stuff and the YouTube algorithm served up several Stark Varg enduro bike videos, which were pretty interesting. It seems for that kind of technical riding, the battery life and bike's capability would probably be better than my endurance and capability. The software interface in which you can dial in how much power, traction, regenerative braking, etc., and set several modes that can be changed on the fly was also quite nice. I expect other brands offer similar tech, but certainly the videos were interesting.
