The vehicle the OP linked has a cargo rating of 375 lb, not 750, and a top (assisted) speed of 15 mph, not 25-30. In the US we don't require special licensing

The vehicle the OP linked has a cargo rating of 375 lb, not 750, and a top (assisted) speed of 15 mph, not 25-30. In the US we don't require special licensing to drive box trucks up to 26,000 lb GVWR, much less a few thousand lb like you're talking about. Requiring licensing for all class 3 ebikes (speed limited to 28 mph, vast majority carrying little to no cargo) would be absurdly disproportionate.
