Common eBike problems and solutions

Hey everyone!

I'm curious to hear about common eBike problems you've encountered, especially when comparing different brands. I've been riding my Aventon Aventure 2 for about six months now, mostly on paved trails and some light gravel, covering around 800 miles. So far, my biggest "issue" has been a slightly finicky display connection on bumpy terrain, but I've heard of more significant motor or battery issues with other brands.

What common problems have you experienced with your eBikes, and more importantly, what solutions did you find, or which brands seem to handle these issues better than others? I'm particularly interested in reliability differences between budget-friendly and mid-range brands.
