This trike certainly seems unique, with a "hub" motor mounted to an open differential. Overall, I think it's well suited for new or "it's been a while" riders that are looking for those car-like comforts but still pack a lot of practicality at a reasonable price. For example, the parking brake and integrated lights would feel perfectly at home for someone who otherwise drives an automobile everywhere.
So while it's slow -- 14 mph (~20 kph) top speed -- that's shouldn't really be an issue, and is quite the benefit since it keeps the range high (~60 miles/~100 km) and means the 500 W motor can likely hold that speed going uphill on paved surfaces. I can easily envision a stoker attachment for parent and child to ride along, without having to worry about possibly unbalancing a two-wheel bicycle. That it's foldable makes it especially apt for those concerned about how to store it at home; I'm not totally convinced the folding feature will be used often to regularly transport the trike to destinations away from home. But it certainly ticks a box for consumers on the fence about buying an ebike or e-trike.
