eBike technology explained

Hey everyone!

I've been riding my new Tern GSD for a few weeks now, mostly hauling groceries and the kids around our hilly neighborhood, and I'm absolutely loving it. The assist is fantastic, but it got me thinking about the tech behind these amazing machines, especially for cargo bikes that carry so much weight. What are some of the key technological differences or considerations you've noticed in cargo e-bikes compared to regular ones, particularly when it comes to motor types, battery capacity, or even frame design? I'm curious to hear your insights!
