RadRover 5 Controller Replacement Guide

The RadRover 5 controller can be replaced if you are instructed to do so by Rad Power Bikes Product Support. Watch the video and follow the instructions below to replace the controller on your RadRover 5.

Tools Needed:

  • Phillips head screwdriver
  • Flat side cutters
  • Zip ties
  • The replacement controller from Rad Power Bikes

The hardware or tools needed for your model may be slightly different. Make sure you use the correct tool and size for your bolts. Always make sure the tool is pressed firmly into the bolt head and turned slowly to prevent damaging the bolt.

Remove the old controller
  1. Get the bike ready for maintenance. Turn off the bike, remove the battery, and press and hold MODE to discharge remaining power.

  2. Unplug the wiring harness connector, which is located inside of the downtube.
    1. Snip zip ties securing the cables at the bottom of the downtube, then use a flat head screwdriver and gentle pinching movements to carefully unseat the rubber grommet. Be careful to not damage the grommet, cables, or frame.

    2. Turn the handlebar to the rider’s right side and gently feed some of the wiring harness cable into the top of the downtube while gently pulling the wiring harness cable at the bottom of the downtube until the connector moves out of the frame. Be careful not to pull so hard that the connector unplugs inside the downtube.
