Common eBike problems and solutions

Hey everyone!

Been riding my RadRover 6 Plus for about a year now, mostly for commuting ~15 miles a day on mixed city/paved trail terrain, and it's been a blast. I'm curious to hear about common issues other Rad Power Bike owners have encountered and, more importantly, how you've solved them. Have you had any recurring problems with things like brakes, motor, or battery, and what was your fix? Sharing tips could really help us all out!
