eBike technology explained

Hey everyone!

I've been riding my Aventon Pace 500.2 for about a year now, mostly for my 10-mile commute through some hilly urban areas. Lately, I've been thinking about how much I rely on the tech, especially when something feels a bit off. I'm curious, what's one piece of eBike technology you wish you understood better when troubleshooting? For me, it's definitely the motor controller – sometimes I feel like it's speaking a different language!
