eBike technology explained

Hey everyone!

Been out on my full-suspension eMTB a ton lately, tackling some gnarly climbs and rocky descents on the local trails. It got me thinking about all the tech packed into these bikes that makes it possible – motors, batteries, torque sensors, cadence sensors, even the displays. What's one piece of eBike technology on your mountain bike that you find most impressive or makes the biggest difference to your ride experience? I'm particularly curious about how different motor types (mid-drive vs. hub) really feel on technical climbs. Let's chat tech!
