Common eBike problems and solutions

Hey everyone!

I'm diving deep into research for my next eBike purchase (leaning towards a commuter/light trail hardtail), and it got me thinking: what are some of the most common problems you've personally encountered with your eBikes, and more importantly, what were your go-to solutions? I'm talking everything from battery woes after a year of daily 20-mile commutes to motor glitches on steep climbs. Knowing what to look out for and how to fix it would be super helpful for anyone looking to buy, myself included!

Cheers!
