Common eBike problems and solutions

Hey everyone!

Been riding my commuter eBike (a RadCity 5 Plus) for about a year now, racking up nearly 2,000 miles on city streets and bike paths, and it's been mostly fantastic. However, I've definitely hit a few snags along the way – everything from mysterious power cut-offs to creaky brakes. It got me thinking: what are some of the most common issues you all have encountered with your eBikes, regardless of type or brand? And more importantly, what clever solutions or DIY fixes have you found? Would love to hear your experiences and tips!
