micromobility is seen as a potential solution to moving people more efficiently around cities"

It's a little sad that we need to actually say this, but:
Don't be an asshole or you will be permanently banned.
Respectful debate is totally OK, criticizing a product is fine, but being verbally abusive will not be tolerated.
Focus on discussing the idea, not attacking the person.

I left out a discussion on the mechanical-electrical-mechanical conversion losses because I wanted to focus on just the chain itself. My argument being: if a chain can do 97%, how on earth will a chainless system do better? Answer: it can't, not for the commonplace bike or ebike.
But you're absolutely right that the double conversion loss must be horrific. Even EVs have contended with a similar choice before and today's hybrids do tend to be parallel hybrids.
Locomotives are, I think, the only widespread application where the benefits outweigh the costs, bevause the cost of a behemoth transmission for a diesel locomotive would be prohibitive to build. Hence, diesel electric locomotives.
