Identify the Symptoms
- Check if the motor abruptly stops working during a ride. Note if it happens under specific conditions like uphill or high-speed situations.
- Observe if restarting the bike temporarily resolves the issue but then recurs.
Inspect the Battery Connection
- Ensure the battery is fully charged. Sometimes, a low battery can cause the motor to cut out unexpectedly.
- Check the battery connection points for any dirt or corrosion. Clean them gently with a cloth to ensure a good connection.
- Ensure the battery is securely attached to the bike. A loose battery can lead to intermittent power loss.
Examine the Wiring and Cables
- Inspect all cables leading to and from the motor for any damage such as cuts, fraying, or loose connections.
- Verify that the wiring to the controller is properly connected and not pinched or stressed.
- If the problem persists, trace each wire to ensure all connections are secure. Loose or damaged wires can prevent the motor from receiving proper signals.
Check the Motor Cutoff Switch
- Inspect the motor cutoff switch, usually located on the brake levers. Ensure it is not stuck in the engaged position, as this can prevent the motor from functioning.
- Engage and disengage the brakes several times to check if the cutoff switch is responsive. If it feels sticky or unresponsive, consider cleaning or replacing it.
Review the Controller Function
- Locate the motor controller, often housed beneath the bike's frame. Make sure it isn’t overheating or showing signs of physical damage.
- If accessible, reset the controller; this sometimes resolves issues caused by minor software glitches.
- Check for any firmware updates from Rad Power Bikes that might address known issues with the motor or controller.
Consult Customer Support
- If the issue persists after performing these checks, contact Rad Power Bikes customer support for professional assistance and additional troubleshooting steps.
- Be ready to provide detailed information about when and how the motor cuts out, as this will help in diagnosing the issue effectively.
