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
- Get the bike ready for maintenance. Turn off the bike, remove the battery, and press and hold MODE to discharge remaining power.
- Unplug the cables connected to the controller.
- Snip the zip ties securing the cables.
- Unplug all connectors from the controller by pulling each connector directly apart, without twisting. Repeat until all connectors are unplugged from the controller.
- Snip the zip ties securing the cables.
- Remove the controller. Use an Allen wrench to remove the controller mounting bolts. Set the bolts aside. Recycle the controller according to local rules.
Continue to the next section to install the new controller.
Install the new controller
- Install the new controller.
- Place the controller in position on the frame so the side with the longest cable points toward the back of the bike. Pass the cables in between the seatstays.
- Center the controller.
- Thread in the four bolts by hand. Tighten the bolts one half-turn at a time, moving in an “X” pattern, until tightened securely.
- Place the controller in position on the frame so the side with the longest cable points toward the back of the bike. Pass the cables in between the seatstays.
- Plug in all connectors. Locate a connector and its matching connector end. Line up the internal notch and pins (and external arrows) and press both sides directly together, without twisting, to connect. Repeat with the remaining connectors.
- Secure any loose cables with zip ties, and trim them to be flush and smooth.
- Check that all cables are out of the way of moving parts. Rotate the handlebar to check that it can move freely and that there is enough cable slack.
- Reinstall the battery, test the bike fully before riding, and ride Rad!
