Common eBike problems and solutions

Hey everyone!

Just wanted to kick off a discussion about common eBike issues we've all probably faced. I'm riding a mid-drive commuter eBike (a Specialized Vado) and after about 3,000 miles, I've had a few minor glitches like creaky pedals and a slightly loose battery connection on rough terrain. What are some of the most frequent problems you've encountered with your eBikes, whether it's motor, battery, or mechanical, and more importantly, what clever solutions did you find? Looking forward to hearing your experiences!
