*REVIEW* Speed Not Showing (Rover)

A faulty speedometer (not showing) can be caused by a faulty multi-cable, motor, or controller.

Isolating the problem to determine the cause is critical in diagnosing the issue.

This article will guide you through how to diagnose each component by following the steps suggested by our technical team.

If a customer's bike is not displaying its speedometer, please try the steps below:

Step 1: Test the Multi Cable

This step will test the multi-cable running from the controller to the connections at the handlebars to check for faults

Note: On some occasions, the junction/connector of the multicable (barrel section where one cable turns to five) can have signs of burnt-out electronic components, which can be evident by a burning smell of plastic or appearance of a disfigured appearance, If this is evident, please confirm the fault using the test method below.  

To do this:

1. Disconnect the 4-5 connections at the handlebars on the faulty bike and the test bike

2. Connect the same connections on the cables from the frame of the test bike to the items on the faulty bike.

3. Disconnect the single plug at the controller end of the test bike and plug it into the controller of the faulty bike

4. Rerun the motor and check the speed readout

If the speedometer works after doing the above test, then the fault is within the multi-cable, and it needs to be replaced asap.

You can reconnect the cables once again by reversing the steps that you have taken.

If the issue is still apparent after the test and motor test, chances are there is a fault with the controller. Proceed to test the controller.

WARNING: Any signs of burning on components, particularly wiring, should be addressed/replaced immediately. Damaged wiring can have more underlying issues besides the speedometer.  This can lead to more serious issues and may cause more significant damage to the e-bike. 

Step 2:  Diagnose by the controller

Check if the controller has not been changed previously.

More often than not, controllers get changed to resolve issues. There are times when incorrect controllers are fitted to the bike so that the customer can use their e-bike again.  While it may sound reasonable, this can cause many problems, and one of them is speedometer issues.

Please follow these procedures to check if the controller is compatible with the bike.

1. Remove the battery from the bike. 

2. Undo 5 bolts underneath the seat. 

3. Remove the seat.

4. Check if the correct controller is installed. Take note of the part number and confirm if this is compatible with the e-bike

. You can also reach out to Dirodi to check compatibility.

Using another controller from the same e-bike model

This procedure involves using a controller from a test bike or a known working spare controller to verify functionality and confirm whether the fault lies with the original controller.

IMPORTANT: Please ensure the spare controller is working properly or the controller on the test bike is the correct model before proceeding. Please make sure that the part numbers of the controller are the same for both ebikes.

To do this:

1. Remove the seat

2. Remove the old controller and replace it with a new one. Make sure all connections are tight and connected correctly

3. Run the motor and check the speedometer to see if it is up and running again.

If the controller is truly at fault, replace the controller by informing the customer of which part number that controller has so that they can jump to our website and make the correct purchase

Step 3: Test using another motor

Installing another motor will help determine if the fault is caused by the motor. It is ideal to use the same spec motor when doing a motor swap test.

To do this:

1. Line up the second bike and disconnect the motor plugs. 

2. Connect the motor of the second bike to first bike

3. Run the motor and check if the speedometer is showing on the display.

If the speedometer appears after installing the test motor, then it is safe to say that the motor is at fault

4. Determine the part number of the motor and provide the link on our website for the new motor.

 UNDER WARRANTY

If the e-bike is still under warranty and was used under normal circumstances, the part that needs replacement must be sent back to us for testing. It is recommended to send a video showing that the part is truly at fault during testing. This can help us speed up our decision-making in granting any warranties for the e-bike.
