Common eBike problems and solutions

Hey Aventon fam!

Hope everyone's enjoying their rides. I'm curious what common issues you've all encountered with your Aventon bikes, and more importantly, how you've solved them. I've got an Aventure.2 with about 500 miles on it, mostly commuting and some light trail riding, and so far so good, but I'm trying to be proactive. Have any of you dealt with things like brake squeal, display glitches, or battery range drops, and what was your fix? Sharing our experiences could really help others down the line!
