Common eBike problems and solutions

Subject: MTB eBike Woes & Wisdom - What are your common issues and fixes?

Hey everyone!

Just got back from a gnarly 30-mile trail ride on my full-suspension eMTB – loved every minute, but it got me thinking about the common quirks and issues we face with these machines. Beyond the usual flats, what are some of the more persistent problems you've encountered with your mountain eBikes, especially on technical terrain or longer rides? Things like motor cut-outs, battery degradation, or even specific component failures? And more importantly, what clever solutions or preventative maintenance tips have you found to keep your e-steeds running smoothly? I'm curious to hear your experiences!
