This guide walks you through removing and replacing the controller on your Ariel Rider e-bike. The replacement process is the reverse of removal, so the same steps apply in reverse order when installing a new controller.

Removing the Controller

1. Remove the Seat

Remove the seat from the bike to gain access to the frame components.

2. Remove the Batteries

1. Remove the top tube battery.

2. Remove the down tube battery from the underside of the frame.

Remove the plate using a 3 mm hex wrench.

4. Disconnect the Battery Balancer

Pull out the battery balancer and disconnect its connectors.

5. Disconnect All Remaining Connectors

Disconnect all other connectors inside the bottom bracket cover area.

6. Free the Controller

1. Flip the zip ties on the motor cable that are holding the controller in place.

2. Unscrew the motor connector and pull it apart.

7. Remove the Seat Post Cover

Remove the four screws from the cover behind the seat post using a 3 mm hex wrench.

8. Slide Out the Controller

Carefully slide the controller out of the frame, making sure the cables do not snag as it comes out.

Remove the two screws holding the controller to the tray using a 3 mm hex wrench.

Installing the Replacement Controller

Installation is the reverse of the removal steps above. Work back from Step 8 to Step 1, reconnecting all connectors and securing all screws and zip ties as you go.
