Common eBike problems and solutions

Hey everyone!

I'm curious to hear about common issues you've encountered with your eBikes and, more importantly, how you've solved them. I've got a Bosch-powered commuter eMTB that I ride about 20 miles a day, mostly paved but with some gravel paths, and I've had a few minor sensor glitches and brake pad woes. What are some of the recurring problems you've faced, whether it's battery degradation, motor noises, or electrical gremlins, and what were your go-to fixes? Let's share some wisdom!
