Quite simply I've seen comments asking for e-bikes to be included in monthly challenges, but I think that this would discredit a lot of pedal powered efforts and worsen the division between traditional cyclists and e-bikers.
A simple solution would be a duplicate monthly challenges for e-bikes (or potentially having an "all-comers").
E-bikes aren't cheating. Some people have limited mobility and can only do what they do because they have the assistance of an e-bike, however, they're putting in more effort than they were before, they're being more eco-conscious than they were before and both of these things need reward and recognition.
Some people (myself included) use e-bikes because it allows us to increase the range of what we would have otherwise done, or allows quicker recovery so we can do more cycling. These still result in one main thing: more cycling.
This is F1 vs Formula E. We're not coming for your spots or your leaderboards, we just want our own sections and our own challenges because we're doing our own sport (which is just a valid).
