    SIGMA bc8.12, a bit confused

    I just got one, and don't quite understand this.

    So the magnet can be anywhere on the wheel? It doesn't have to be closer to the tire? Wouldn't where you put the magnet affect the MPH reading?

    the RPM of the wheel is the same, no matter if you put it near the axle or near the rim.

    Well, that's not that big of a problem anymore, as I just fitted it all on and it doesn't work! :/ The display is all zeroes, despite a spinning wheel. The distance of the magnets are fine, and I can't find any problems...
