I was not very happy with the wheel speed sensor cable management on my Whyte E160 so I made this small guide to ensure a stick or other cannot push the cable into the back wheel tire which would ruin a day of riding.  I think it will suit a Whyte E180 as well.  Printed in TPU you need a double sided tape to attach it to the bike, or a contact glue should also work.  The cable is a push fit into the guide. 

The photo below shows the cable looking down from above the rear suspension linkage, the cable has enough length to allow for suspension movement and with this enough length to get caught in a tire tread. 

This photo show the cable from the underside of the rear stay/suspension linkage.
