Watch the video, read through the instructions below, and contact Rad Power Bikes Technical Support if you have questions. If you are not confident in your ability to successfully and safely perform all steps, we recommend having the work performed by a local, certified, and reputable bike mechanic.
1. Power off the bike. Ensure the bike is in the off position and use the key to remove the battery. Once removed, press and hold the “MODE” button on the LCD Display Remote until the display remains off for about two seconds (it may flash on briefly). This ensures the power is fully discharged from the bike and it is safe to work on.
2. Snip the zip ties holding the controller cables to other cables and the bike frame, using caution to avoid damage to the cables, paint, and frame.
3. Disconnect the motor connector, wiring harness, PAS sensor, and battery connector by holding each side of the connector housing and pulling directly apart without twisting.
4. Remove the old controller by using a Phillips head screwdriver to remove the four bolts that attach the controller to the frame.
5. Attach the new controller to the frame by using a Phillips head screwdriver to re-attach the bolts and securely hold the controller to the frame.
6. Reconnect the four connectors. Locate the wiring harness, PAS sensor, the battery, and motor cable connectors. For each connector, align the internal pins and external arrows and carefully press the connector ends directly together without twisting to fully seat the connection.
7. Zip tie the controller cables. Use replacement zip ties to attach the motor cable to the chainstay on the frame, the other locations where cables were bundled and attached to the frame, and carefully snip the zip tie excess.
8. Reinstall the battery, test the bike fully, and have your work inspected by a certified, reputable bike mechanic.
