Introduction
You might have to replace the controller on your Swift Lite 4 or Stunner Lite 2 bike in some cases when errors occur. Follow these instructions to replace this part!
You will need the following tools:
Phillips Screwdriver
Electrical Tape (Optional)
Step 1
Remove the battery from your bike. Discharge all electricity from the system by holding down the POWER BUTTON for your display.
Go to the Non-Drive side of the bike. Remove the 4 screws securing the "Controller Cavity Cover" to your bike with a phillips screwdriver.
With all screws removed, you can remove the "Controller Cavity Cover" and access the controller, as shown in the second image.
Step 2
Take a picture of the controller within the cavity. Then remove the controller from this cavity.
Take a picture of how ALL connectors are attached on the controller and eBike to reference when reinstalling, in case you encounter any trouble.
Take the old controller and the new one. Swap connections one at a time in the following manner:
Unplug one connector from the old controller.
Plug this connector into the matching connection on the NEW controller.
Repeat until ALL CONNECTORS are plugged into the NEW controller.
Step 3
With your new controller plugged in, reinsert it into the controller cavity.
Reinstall the "Controller Cavity Cover", reusing the 4 screws previously securing it to the bike with the phillips screwdriver.
Your controller is now reinstalled!
