First, my joystick stays on the battery percent and will not move to the odometer or anything else? Secondly, my battery stops functioning at about 26% and I lose power? I believe my battery cells are dying, but not sure? A new battery is about $1,000, very expensive. Any feedback would be much appreciated. FYI: I ride 5,000 to 6,000 miles/year And am the original owner of the bike.
