AL_BUNDY, did you see my initial reply on this thread? I think you have the sensor installed incorrectly on the bike after looking at the instructions. Isn't that circular bump the actual sensor? If it is, you have it pointed forward on the mountain bike, and upward (sky) on the red bike. From the instructions, it appears the sensor should be pointed to the magnet on the spoke, and within 2 mm.
