Wheel magnet alignment
–
“Error 21”
Wheel speed sensor alignment is critical to the function of your speedometer. The wheel speed sensor
underneath the frame interacts with a magnet mounted onto one spoke on the rear wheel of your
Dualie. The speedometer calculates your speed using this sensor and magnet to count rotations/second
and translate that in real-time to your actual speed in mph (kph). If the speed sensor is not aligned with
the magnet, the speedometer will fail to operate. You
will see “Error 21” appear on your display.
Though we align and test all sensor and magnets at the factory, wheel removal or accident may cause
the magnet to change alignment.
1.
Check that the sensor is in place. It is found inside the left chain stay. Check the image below
and verify the same sensor is on your Dualie. If not contact Rungu or go online to obtain a
replacement sensor.
2.
Check that the cabling attached to the sensor is attached to the motor.
