Thing is, very few of those climbs will actually not have been done (or be do-able) by a fitter more skilled rider on a normal mtb. All the Ebike is doing is allowing folk with less skill/fitness do what the fitter/stronger/more skilled/experienced rider can. but without the skills you're also going to get more pedal strikesTo me the most obvious thing is being able to get places you wouldn’t have managed on a regular bike.
I find myself attempting, and a lot of the time succeeding to climb sections that I would normally just have leapt off and pushed up.
The feeling of achievement from cleaning a climb like in your pic on a normal mtb will be pretty great. On an Emtb not so much.
