• Attach the rubber part to the sensor (picture 3).
• Pass the cable ties through the speed sensor and
rubber part holes. (picture 4).
• Adjust the sensor to the front fork so that the
POLAR logo faces outwards. Adjust the ties loosely.
Do not tighten them fully yet. (Picture 5.)
• Attach the magnet to a spoke at the same level as
the sensor. The magnet hole must be facing the
speed sensor. Fasten the magnet to the spoke and
tighten it loosely with a screwdriver. Do not tighten
it fully yet. (Picture 6.)
• Fine-tune the positioning of both the magnet and
the speed sensor so that the magnet passes close
to the sensor but does not touch it. Adjust the
sensor towards the wheel/spokes as much as
possible. The maximum distance between the sensor
and the magnet should be 4 mm/0'16''. The gap
is correct when you can fi t a cable tie just about
between the magnet and the sensor (picture 6).
• Rotate the front tyre so that you can see a speed
reading on the display of your cycling computer.
The reading indicates that the magnet and the
speed sensor are positioned correctly. Once the
magnet and the speed sensor are positioned
correctly, tighten the screw to the magnet with a
screwdriver. Also tighten the cable ties securely and
cut off any excess cable tie ends.
Your safety is important to us. While riding your
bike, please keep your eyes on the road to prevent
any accidents and injury. Check that you can turn the
handlebar normally and that the cable wires for brakes
or gearing do not catch on the bike mount or the
speed sensor. Check also that the bike mount or speed
sensor does not hamper pedaling or the use of brakes
or gearing.
Before you start cycling, you should set the wheel size
of your bicycle into the cycling computer. For further
information on how to use the Polar Speed Sensor
with the cycling computer, please refer to the user
manual of the cycling computer in question.
