Common eBike problems and solutions

Hey everyone!

Just wanted to kick off a discussion here. I've been riding my Aventon Level.2 for about a year now, mostly for commuting ~15 miles round trip daily, and it's been fantastic. But like any machine, I've had a couple of minor hiccups – mostly related to brake adjustments and a weird creak from the bottom bracket that eventually sorted itself out.

What are some of the most common eBike problems you've encountered, and more importantly, what clever solutions or DIY fixes have you found? I'm particularly interested in battery care tips or motor-related issues folks have faced. Let's share some wisdom!
