Not OP, but the cero one is one I found that seems to check the boxes. It’s a cargo bike that was inspired by japanese mamachari bikes - very utilitarian bikes that are analogs to the dutch commuter bikes.

I just purchased a used, older version that still uses a chain instead of a belt, but it handles nicely. Built in frame lock is incredibly convenient!

Sorry, I was thinking of the pinion edrive. https://pinion.eu/en/e-drive/
