Can the maker of the bikes be identified?

On the differently organized end, I saw this summer in Europe a host of riders with black cube boxes on their back marked as Uber delivery, I think UberEats.
Where I live they are mainly used by Domino's, or only Domino's, I haven't seen them used by any other company. They are pretty fast, the bikes I mean, don't know about the delivery because I don't eat from Domino's.
