Two halves are required for the wheel sensor to function:
1. A magnet, on the spinning part of the wheel.
2. A speed sensor, on the non-spinning part of the wheel.
The magnet spins around tripping the sensor switch each time--giving
speed, distance and time data to compare with the GPS data.
The magnet is installed on the brake rotor because it spins with the wheel.
The provided magnetic bolt replaces a stock rotor bolt. If that will not work,
glue the spare magnet in a hole on the brake rotor. (JB Weld or a similar
slow-cure epoxy works well.)
After the magnet is in, the sensor is placed on a non-spinning part the
wheel, rotor shield, or bracket.
Many Motorcycles and ATVs have special installation procedures. Refer to the
online model-specific instructions for more information.
Wheel Size
Knowing your exact wheel size is critical for the wheel sensor to calculate
correct speed and distance data. The more accurate the wheel size, the
better Voyager Pro performs.
