Common eBike problems and solutions

Hey everyone!

Just got back from a killer 20-mile ride on my Specialized Levo SL, mostly singletrack and some gnarly climbs. It got me thinking about common issues we face with our mountain eBikes. I've had a few minor things pop up, like a creaky bottom bracket after a super muddy ride, or a sensor acting up.

What are some of the most frequent problems you've encountered with your full-suspension eMTBs, and more importantly, what clever solutions or preventative maintenance tips have you found to keep them running smoothly out on the trails? Share your wisdom!
