Common eBike problems and solutions

Hey everyone!

Just picked up a new folding eBike (a RadExpand 5, if anyone's curious!) and I'm loving the portability for my city commutes and weekend adventures. It got me thinking, what are some of the most common issues you've encountered with your folding eBikes, and more importantly, what clever solutions have you found? I'm particularly interested in things like hinge creaks, cable management when folded, or even battery life quirks. Share your wisdom!
