Shimano STEPS
Sensors
W011
No speed signal from speed sensor
The system is not receiving a bicycle speed signal from the speed sensor. Because the system cannot verify the riding speed, the maximum speed up to which assist is provided is lowered. The usual cause is a shifted spoke magnet or a wrongly positioned or disconnected sensor.
