Common eBike problems and solutions

Hey everyone! Just joined the forum and super excited to be part of the community. I've been riding my Aventon Level 2 for about six months now, mostly for commuting ~15 miles round trip on mixed urban terrain, and it's been awesome.

I was wondering, what are some of the most common issues you've encountered with your eBikes, and more importantly, what clever solutions or preventative maintenance tips have you found? I'm particularly curious about battery longevity and drivetrain wear given the extra power. Let's share some wisdom!
