Rear Hub Wiring Gaurd

[KTMDAD]

I have already broken the wiring harness coming out of my rear hub motor.
Once I replace it, what are people using as a guard to protect the harness at that point?

I tye-wrap it to the fork, on the top. Mine is on the front fork. 10000 miles I haven't broken the motor connector yet. There is split tube pvc cable wrap , but the 1" diameter size you have to buy a whole roll somewhere. The 1 cm size is sold at any auto supply in the wiring section. This 32 mm diameter sleeve is only $52 for a 50 m roll https://www.newark.com/multicomp/pp001374/hookloop-braided-wrap-pe-50m/dp/18AC8205?st=cable wrap
Newer hubs have a 11 pin juli connector, which is pretty rugged. My older motors have the 6 pin plastic rectangular connector on the hall effect sense wires, and three .157" bullet connectors on the phase wires.

It's difficult to protect a plastic connector if you bounce it off a rock or other hard surface. To keep from snagging them on road debris like brush or sticks, I use spiral wrap:

It isn't pretty but it keeps the sharp edges on most connectors from getting caught on road debris . The wrap also offers some impact protection from stones kicked up by the tires.

You might try a derailleur guard? It should mount no problem to the non drive side and they are pretty cheap.

Grin had a steel guard. Basically a U
shape slotted for the axle and protection for the wire. These days better motors no longer have wiring out of the axle. Pretty easy to fabricate.
