Common eBike problems and solutions

Hey everyone!

I'm diving deep into research for my next eBike purchase (thinking about a full-suspension eMTB for some trail riding, maybe 50-mile range), and I'm trying to get ahead of potential headaches. For those of you who've owned eBikes for a while, what are some of the most common problems you've encountered, and more importantly, what were your go-to solutions or preventative measures? Any specific issues with batteries, motors, or even just general wear and tear on components that differ from a regular bike? Your insights would be super helpful for anyone looking to buy!
