Yes I've experienced the a speed error W011 and thought it was the sensor fail
but it turned out to be a human error.
Fragile Shimano STEPs connector
The Speed sensor was probably OK but the Shimano STEP SD50 connector socket
may fail agains clumsy people without the Shimano connector tool...
Hi I'm new here.
I had recently a problem with the speed sensor on one of our 2 Shimano Steps bikes.
Got no spead reading and an error W011 wheen rotating the back wheel.
First I thought the magnet on the back wheel spookes was in the wrong place or
something stupid. But it was correctly...
