eBike technology explained

Subject: Let's talk tech! What eBike components baffle you most?

Hey Engwe fam! 👋 I've been riding my Engwe EP-2 Pro for a few months now, mostly for commuting and some weekend trail rides, and I'm constantly impressed with how smoothly everything works. It got me thinking about all the tech packed into these bikes.

I'm curious, what part of eBike technology do you find most interesting, or maybe even a little confusing? Is it the motor types (hub vs. mid-drive), battery chemistry, or maybe the controller settings? Let's geek out a bit and share what we've learned or what we'd love to understand better!
