Few of the e-bikes are designed for serious use as they lack strong rear racks for panniers or even a way to attach an after market bike rack by providing bosses in the frame. I bought the Yamee bikes in large part due to their having very strong rear racks that could support a 50 lbs. load. This is why I would favor a bike like the Blix Vika+ over the Fiido bikes.
I use a Burley Travoy with my folding bike (with e-assist). Can easily pull 60lbs with fantastic tracking; becomes my shopping cart in the store. That means I don't have to have the added weight of racks on the bike itself so it is super light, easy to carry up stairs, etc. And I can even attach the folded bike to the trailer and roll it if I want.
