My bike's display goes blank and the motor cuts out when I get down to 3bars, probably closer to 2, and climbing a hill towards the end of my 11 commute home. It seems to work fine when the battery is more fill. My bike is just over two years old and I have only about 1300 miles on it. Is it my motor? It's seems more like my battery is starting to degrade. What do you guys think? How long do these batteries last? How do they act when they're starting to go? Any deals to be had on easy motion Neo batteries??
