eBike technology explained

Hey everyone!

Just got my first eBike last month – a RadRover 6 Plus, and I'm absolutely loving it for my daily 10-mile commute over some hilly terrain. It's amazing how much assistance it provides! I'm curious about the tech behind it all, especially things like motor types (hub vs. mid-drive), battery chemistry, and controller functions. What are some of the key technological advancements in eBikes that you find most interesting or impactful? Looking forward to learning more!
