Mounting of the bike computer magnet and sensor

For a bicycle, the magnet sensor (10) is positioned vertically along the bicycle fork. The magnet (11) is positioned on one of the wheel spokes so that for each wheel rotation it passes  near the vertical end of the sensor either at point (7) or the same position at the other end.



Mounting the magnet so it activates the sensor in the orientation as shown in the image below also works well. Using my hand to pass the magnet past the magnet sensor several times activates the bike computer and the distance value recorded is incremented.



Using "Blu-tack" I mounted the magnet on the inside of one of the front skateboard wheels. In addition I mounted the magnetic sensor with its length in parallel with the truck stem connecting to the wheel.
