Speed Sensor (standard)
The speed sensor (1) and its spoke magnet (2) must
be fitted such that the spoke magnet moves past the
speed sensor at a distance of at least 5 mm and at
most 17 mm with each rotation of the wheel.
Note: If the distance between the speed sensor (1)
and the spoke magnet (2) is too small or too large, or
if the speed sensor (1) is not properly connected, the
speedometer display will fail and the drive unit will
operate in emergency mode.
Should this occur, loosen the screw of the spoke mag-
net (2) and fasten the spoke magnet to the spoke
such that it runs past the marking on the speed sen-
sor at the correct clearance. If the speed is still not
being indicated on the speedometer display after do-
ing this, please contact an authorized bicycle dealer.
When changing a wheel, make sure that the sensor
cable is routed so that it is not under tension and has
no kinks.
