I have a NCM Aspen and I've noticed that the same problem arises typically after I have ridden it for a little while, turned it off for an hour or so, and then have ridden it again. The odometer and speedometer quit working and then the display cuts off say every 5 minutes. Its really annoying. I have tried contacting leoncycle but I'm still waiting on a call. Please offer your opinions on what this could be. My guess is the controller. Anyone else encountered this?
