Common eBike problems and solutions

Hey everyone!

I'm curious about what common eBike problems you've encountered and, more importantly, how you've solved them. I've got a mid-drive commuter eBike that I ride about 20 miles daily on mixed city and paved trail terrain, and I've had a few minor issues like brake pad wear and chain skipping. What are some of the recurring headaches you've faced with your eBikes (hub-drive, mid-drive, full-suspension, etc.) and what were your go-to fixes? Sharing our experiences could really help others out!
