Common eBike problems and solutions

Hey everyone!

Just got back from a great 20-mile ride on my fat tire eBike (a RadRover 6 Plus, if anyone's curious) and it got me thinking. We often talk about the fun parts, but what are some of the most common issues you've encountered with your fat tire eBikes, especially when riding on varied terrain like sand, snow, or even just rough trails? I'm curious about everything from motor hiccups to battery degradation or even just annoying flats. What solutions have you found work best? Let's share some wisdom!
