Common eBike problems and solutions

Hey everyone!

Just got back from a great ride on my fat tire eBike (a RadRover 6 Plus, if anyone's curious) – did about 20 miles on some mixed gravel paths and sandy trails today. It got me thinking about common issues we face with these beasts. What are some of the most frequent problems you've encountered with your fat tire eBikes, and more importantly, what clever solutions have you found? I'm particularly interested in anything related to motor/battery longevity or tire issues on rough terrain. Let's share some wisdom!
