Common eBike problems and solutions

Hey everyone!

I'm curious to hear about common eBike issues you've encountered and, more importantly, how you solved them. I've been riding my fat-tire eMTB (a RadRover 6 Plus) for about a year now, mostly on trails and some city commuting, racking up around 1500 miles. So far, my biggest 'problem' has just been a few flats and some brake squeal, but I'm sure others have faced more complex stuff.

What are some of the recurring problems you've seen or experienced with your eBikes (regardless of type – commuter, cargo, mountain, etc.) and what was your go-to fix? Thinking about things like battery degradation, motor issues, controller glitches, or even just persistent creaks. Let's share some wisdom!
