How hard can you grab your brakes and shed momentum when stopping an e-cargo bike traveling at 25-30 mph and with 750 pounds of cargo plus human? When do bike tires lose their grip on dry, wet, icy, and sandy roads?
I've driven trucks with 1000-3000lb loads. I understand how handling changes between vehicle types (different masses and 2 vs. 4 vs 6 wheels). My experience is why I advocate for specialized training and licensing for class 3 e-bikes and cargo bikes. I also suggest cargo bike training should include securing and balancing a load because I've seen too many improperly secured loads by idiots putting themselves and others at risk.
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.
