Like any technological product, electric bicycles may encounter unexpected issues during use. Some riders have reported that their e-bikes move backward when starting or riding at low speeds, causing a loss of balance. Additionally, this backward movement can affect the bike’s handling, making the riding experience unstable and reducing overall safety. In this article, we will explore the possible reasons behind this phenomenon and provide effective solutions to help you restore normal riding and ensure a safe and stable journey.
Motor Issues
One of the main culprits when an electric bicycle starts moving backward is the motor. Several factors could be affecting its performance:
- Controller Malfunction: The controller is the brain of the electric bicycle, managing the power flow to the motor. If there is an issue with the controller, such as a short circuit or incorrect configuration, the motor may behave erratically, including moving in reverse.
- Damaged Motor: In some cases, an internal component of the motor may be damaged or worn out. This can cause the motor to function incorrectly and spin in the opposite direction.
Symptoms include the e-bike moving backward immediately upon startup or experiencing abnormal vibrations and reverse movement at low speeds. This may indicate issues with the motor or controller. Check if the controller is compatible with the motor, look for error codes, and observe whether the motor produces unusual noises or resistance to rule out damage or short circuits.
Battery Problems
Batteries also play a crucial role in the operation of an electric bicycle. Issues with the battery can be another reason why the bicycle moves in reverse.
- Low Battery Charge: When the battery is about to run out, it is common for the bicycle to malfunction. This can manifest as a lack of power or even the motor running in reverse.
- Battery Connection Issues: If the battery cables are loose or improperly connected, the motor may not receive the correct amount of power, leading to erratic behavior, such as moving in reverse.
Symptoms include the bike reversing when the battery is low or temporarily returning to normal after a full charge but malfunctioning again as the charge drops. This may be due to insufficient power supply or loose connections. Ensure the battery is fully charged, check for secure and corrosion-free terminals, and try reinstalling the battery for testing.
Sensor Issues
Electric bicycles are equipped with various sensors that help manage motor operation and pedal assist. If any of these sensors fail, the motor may behave abnormally.
- Speed Sensor Malfunction: The speed sensor is responsible for measuring how fast the bicycle is moving. If this sensor is not functioning correctly, it could send incorrect information to the controller, causing the motor to spin in the wrong direction.
- Pedal Sensor Issue: The pedal sensor assists the motor when it detects that the rider is pedaling. If this sensor is damaged or misaligned, the motor may receive incorrect signals and start moving backward.
Symptoms include incorrect speedometer readings or the motor engaging even without pedaling, sometimes moving in reverse. This may indicate a faulty speed or pedal sensor. Check for unusual speed data fluctuations, test sensor response with a magnet, and try pedaling in different directions to determine the issue.
User Operation Errors
Sometimes, issues with an electric bicycle are not related to technical failures but rather user operation errors.
- Improper Use: Some riding modes or specific settings could cause the motor to function incorrectly if not used properly. For example, trying to use the bike in a high gear while the battery is low may result in a malfunction.
- Incorrect Configuration: If the electric bicycle’s settings are not properly configured, some functions may not operate as expected, including the motor running in the wrong direction.
Symptoms include reverse movement occurring only in specific modes or gears, which may result from incorrect riding mode settings or improper operation. Ensure no special modes (such as reverse mode) are activated, try switching gears or resetting to factory settings, and check whether a recent firmware update has caused any irregularities.
Maintenance and Care
To prevent an electric bicycle from experiencing issues such as moving in reverse, regular maintenance is essential. Be sure to periodically check the motor, battery, and sensors. Additionally, if you lack technical knowledge, it is advisable to take your bicycle to a specialized workshop for a professional inspection.

What to Do If Your Electric Bicycle Moves in Reverse
If you find yourself in a situation where your electric bicycle starts moving in reverse, here are some steps to follow:
- Turn Off the Motor: Immediately deactivate the motor and ensure the bicycle is in a safe location. This will prevent any further accidents.
- Check the Battery: Ensure the battery is fully charged and all connections are secure. Look for loose or damaged cables.
- Inspect the Controls: Verify that the bicycle’s controls are set correctly and that no riding modes could be causing this issue.
- Consult the Manual: Refer to the user manual to see if there are specific troubleshooting steps for this problem.
- Contact a Professional: If you are unable to resolve the issue on your own, it is advisable to consult a specialized technician or contact Fiido’s customer service.
