Ok, now I'm officially confused ... I thought that the intent of my post was obvious. But this being your thread, the least I can do is have the courtesy of explaining myself.

Although said motors' rpm's are rather low for direct application on moving vehicles, their extremely high efficiency, plus their use of conventional and inexpensive materials make them candidate for adaptation into EVs by simply adding a gearbox to increase their output speed. The decrease in efficiency due to the presence of said gearbox could be justified by their higher power to weight ratio, and their manufacturing cost. Which may result in a better alternative than the PMSMs currently being used in most EVs.

Fair enough.
Their website doesn't mention that, but if the motor can be sized to power an EV (in the 100kW range, or more than a hundred horsepower), then adding a step-up gearbox could be an option.
