eBike technology explained

Hey everyone! New here and super excited to dive into all things eBike.

I've been riding my Aventon Level 2 for a few months now, mostly for my 15-mile round trip commute with some hills, and I'm constantly amazed by how much technology is packed into these bikes. I'm really curious to hear from others about what specific eBike tech aspects you find most interesting or perhaps confusing. Are there any particular components, like motor types, battery chemistry, or even controller algorithms, that you'd love to see explained in more detail? Let's get a good discussion going!
