eBike technology explained

Hey everyone!

I'm looking to upgrade my eMTB soon, and I've been diving deep into all the different tech out there – from motor types and torque sensors to battery chemistry and display features. It feels like every brand has its own jargon! What's one piece of eBike technology you think is most important for a good riding experience, especially when considering a new purchase? Are there any "must-have" tech features you'd recommend looking for in the current market?
