I agree that recording an ebike activity as a powered human is incorrect because it distorts the ranking of segments.But the challenges are personal and do not concern others.Why then make ebikes ineligible for challenges?Personally,i use equal parts of a human road bike and an e gravel bike with as much energy expenditure in one case as in the other.Not being able to count my electric outings in my challenges will lead me to forget about it.Or not to declare them as electric.
