Hi I have been having problems with my computer. It only seems to happen after i ride to work, leave the bike for about 10 hrs then when i get on the bike to come home and turn on the computer it starts giving me multiple readings. The first one is that I'm going fast then the next one says that I'm going slower and it alternates between the two, and this is before I even start riding. As I start riding the speeds change but always alternate between two different speeds, one high and one low. They are nowhere near accurate to the speed I'm actually going. When i stop, they still flash and do not go to zero. I have changed the batteries but after a couple weeks they started again. The sensor on the wheel is aligned properly. Any thoughts?
