Alignment of the Raleigh Array chain ring sensor (Hub gear bike)
1.
Check the sensor is positioned perpendicular to the chain ring. If the sensor is not
perpendicular to the chain ring adjust accordingly.
2.
Adjust the bracket by removing the prop stand, loosening the two fixing screws and sliding
the bracket until the sensor is approximately 1mm away from the chain ring. Rotate the
cranks making sure the sensor doesn’t contact the chain ring at any point of its rotation.
3.
Adjust the sensor along the slot of the bracket. The right hand edge of the sensor should sit
5 – 8mm inside the outer diameter of the chain ring.
4.
Test ride the bike, the motor when adjusted correctly will give continuous power while
pedalling below 25km/h.
