Mounting position Speedsensor

The speed of the e-bike is measured with support of a magnet (item 2 in Fig. 

1) which triggers pulses at the speed sensor (item 1 in Fig. 1). The Speedsensor 

and magnet are mounted at manufacturer with a distance between 1 mm and 

8 mm (see Fig. 1) in the area of the rear wheel.

NOTE

 

Check the correct distance between Speedsensor and magnet if the 

speed Display shows incorrect values or fails.

 

When performing installation work on the rear wheel, make sure that 

you do not damage the sensor or the sensor bracket. All work such as 

repair, assembly, service and maintenance carried out exclusively by a 

bicycle dealer authorized by TQ.

 

Make sure that the Speedsensor and magnet are free of dirt to avoid 

signal interference.
