All my friends are very much into mountain biking and a couple of them work in the industry (Spot Bikes, please support if you're in the market!) They've had a holier-than-thou attitude about e-bikes for years and they're actually outlawed on a lot of trails around here. But my buddy's cystic fibrosis progressed to the point he couldn't handle the climbs anymore and he switched to an e-bike and it has been a life-changing experience for him. He bikes all the time when it was totally out of the game before. IMO, perfect use case for eMTB, to level the playing field and accessibility. Other than that, it's kind of a cheat, IMO, and I'm in really bad biking shape lol. E-towny bikes though--for a lot of people that can replace owning a car altogether.
