eBike technology explained

Hey everyone!

Been thinking a lot lately about how far eBike tech has come, and honestly, it's pretty mind-boggling. From hub motors to mid-drives, different battery chemistries, and even integrated displays with GPS – there's so much going on under the hood!

I'm curious, what's one piece of eBike technology that really impresses you, or maybe something you'd like to understand better? For me, it's the torque sensors; they make my commuter eMTB feel so natural on those steep climbs. What about you all?
