Common eBike problems and solutions

Hey everyone!

Just joined the forum and excited to connect with fellow eBike riders. 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 fantastic. I'm curious what common issues you all have encountered with your eBikes, regardless of brand or type, and more importantly, how you've solved them? I'm hoping to learn some preventative tips and quick fixes from the community!
