Common eBike problems and solutions

Hey everyone!

Just joined the forum and super excited to be here. I've been riding my Aventon Pace 500.2 for about a year now, mostly for commuting ~15 miles round trip daily, and it's been fantastic. However, I've had a few minor hiccups, like a weird creak from the motor area that comes and goes, and I'm curious what common issues others have run into with their eBikes. What are some of the most frequent problems you've encountered, and more importantly, what clever solutions or DIY fixes have you found? Looking forward to hearing your experiences!
