So I see someone selling these on Ebay and they are getting a reading from the odometer without the bike even being turned on! How the hell can they do this? Is there some type of a back-up battery inside it so it does not forget the mileage? that would make sense to me. But how can I get a reading using this "back-up" battery if there is one. Obviously there is a way since this guy is doing it. I emailed him through Ebay but not sure if I will get a response so I hopes someone here may know. Thanks!
