Electric Bike Conversion Kit - Motor Wire Protector Installation
The optional motor wire protector bracket will shield your motor wire from damage. If your bike falls over or is involved in an accident, the motor wire protector will keep the wire from being cut.
Detailed instructions are available in the E-BikeKit manual, E-TrikeKit manual.
To install the motor wire protector:
Loosen the axle nut on the wire side
Slip the protector on, lining it up so the wire passes through it cleanly.
You should use a c-washer or outside washer to keep the bracket from touching the bike frame
Tighten the axle nut and make sure that the protector doesn't touch the frame, and the axle nut tightens evenly.
