Label Wires If Necessary

If your e-bike’s wiring system is particularly complex, consider labeling the wires with masking tape and a marker. This will help you easily identify each wire during installation and minimize the risk of making incorrect connections.

Removing The Old Controller

This section will guide you through removing the old controller from your electric bike.

The objective is to ensure a seamless transition while maintaining the integrity of your e-bike’s components. Follow these steps carefully to prepare for the installation of your new controller.

Locate The Controller on the E-Bike

Before removing the old controller, you must identify its location on your e-bike. Controllers are typically housed in various places, including under the seat, within the frame, or attached to the rear rack.

Consult your e-bike’s manual, or look for a box-like component with multiple wires.

Disconnect All Connectors and Wires

Once you have located the controller, carefully disconnect all the connectors and wires attached. Keep track of each connection, which will be crucial when installing the new controller. If necessary, use a small flathead screwdriver to release the locking mechanisms on the connectors.

Unscrew And remove the Controller from The Frame

After disconnecting all wires, unscrew the old controller from its mounting points on the frame. Store the screws safely, as you may need them to mount the new controller.

Gently remove the controller from the frame, not damaging any components or wiring.

Compare The Old and New Controllers to Ensure Compatibility

Before installing, compare the old and new controllers to confirm their compatibility. Check for similarities in size, mounting points, and connector types. If you notice any significant differences, consult the manufacturer or a professional technician for guidance.
