Speed Sensor
Speed is the number of distance of the wheels set per minute for cyclists.
Installing Speed Sensor
 The speed senor comes in two parts, the speed sensor itself and the magnet. You can choose to
install the speed sensor/magnet to the fork/front wheel spoke or the chain stay/back wheel spoke of
your bike as long as the magnet is at the same level of the speed sensor and the spacing of the two
should not exceed 25 millimeters
 Use two cable ties to secure the speed sensor to the fork or chain stay of your bike.
 Attach the magnet to the wheel spoke. The magnet must be facing the speed sensor. For the spoke
is too thin for the magnet to attach by cable ties, users should tighten the magnet screw instead of
using cable ties.
 The magnet and speed sensor should pass facing each other with no more than 25 millimeters
between the two to transmit accurate data.
The details please reference for below:

Unscrew the magnet to open it.
Open the magnet without separating the cases
apart.
Attach the magnet to a spoke of the rear wheel by
threading the spoke through the U-shaped
indentation on both sides of the magnet.
