4. Attach the magnet to a spoke at the same
level as the speed sensor (picture 4 on the
back cover). There is a small caved dot on
the backside of the sensor (picture 1 A on
the front cover), which indicates the spot
the magnet should be pointing at when
passing the sensor. Fasten the magnet to
the spoke and tighten it lightly with a
screwdriver. Do not tighten it fully yet.
5. 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 (picture 4 on the back cover).
Move the sensor towards the wheel/spokes
as close as possible. The gap between the
sensor and the magnet should be under 4
mm/0.16’’. The gap is correct when you
can fit a cable tie between the magnet and
the sensor.
6. Rotate the front tire to test the speed
sensor. The flashing red light on the sensor
indicates that the magnet and the sensor
are positioned correctly. If you keep
rotating the tire, the light will stop flashing.
Tighten the screw to the magnet with a
screwdriver. Also tighten the cable ties
securely and cut off any excess cable tie
ends.
Before you start cycling, set the wheel size of
your bicycle into the receiving device or
mobile application.
