Common eBike problems and solutions

Hey everyone!

Just got back from a great 20-mile ride on my Aventon Level 2, mostly paved trails with a few hills. It got me thinking about common eBike issues. What are some of the most frequent problems you've encountered with your eBikes, regardless of brand or type (hub vs. mid-drive)? And more importantly, what clever solutions or workarounds have you found? I'm curious about everything from battery degradation to motor quirks or even just annoying creaks!
