Planet Bike speedometer won't reset I have a planet bike speedometer and after the winter season it seems that it is no longer functioning. It will come on when the bike starts to move but I cannot reset it and it seems to be frozen on the stats of my last ride where it was working. Does anyone know if this is a battery issue or just a malfunction of the device. If I have to get a new one how expensive and time consuming would it be to replace?
I suggest taking the battery out, waiting a minute, then replace it. While you have it out rub the battery on a dry rag to clean it, and clean the battery contacts and inside of the speedo too. If it works after that you have a cheap, easy fix.

The other solution is to buy a new, cheap speedo. You can get speedos from about $AUS10 on ebay, so if your requirement is just speed and distance that's going to be the quickest, cheapest way to go.
