eBike technology explained

Hey everyone!

I've been riding my new Aventon Level.2 for a few months now, mostly for my 10-mile commute and some weekend trail rides, and I'm really impressed with the torque sensor technology – it feels so natural compared to my old cadence sensor bike. It got me thinking: how much do different brands really vary in their implementation of core eBike tech like motor types (hub vs. mid-drive), battery management systems, or even display interfaces? Are there any specific brands you feel truly excel in certain tech aspects, or perhaps lag behind? I'm curious to hear your experiences and insights!
