As an avid rider for ~40years as well. Raced: road, criterium, MB (XC, DH, enduro). For a while I was very against the concept of pedal assisted bikes for enthusiasts. That said they have taken over here in AK. And my next trail/all mountain bike will very likely be an eBike. I’m thinking something similar to the Kenevo with a duel crown fork.
My typical summer loop is a mix of a little of everything from XC and flow to Tech DH/park, 3k vertical feet over ~15 miles up then down from my house.
My teens do the loop in 3-4 hrs, I do it in closer to 4. My buddies with e bikes do it in 2 hrs.
