Common eBike problems and solutions

Hey everyone!

Just got back from a fantastic 30-mile ride on my Aventon Pace 500.3, mostly paved trails with some decent hills, and it got me thinking. While eBikes are generally awesome, what are some of the most common issues you've encountered with your own bikes, and more importantly, what clever solutions have you found? I'm curious about everything from battery quirks to motor noises or even just annoying little rattles. Share your wisdom!
