How to Change Cadence Sensor on Electric Bike?

Updated: Apr 16

Welcome to our comprehensive guide on maintaining a key component of your GIN X Electric Bike – the cadence sensor. Whether you're a seasoned e-bike enthusiast or a newcomer to the world of electric bicycles, understanding how to service and manage your bike's cadence sensor is crucial for ensuring a smooth and enjoyable riding experience.


Essential tools for cadence sensor removal


Before you start, make sure you have the following tools at hand:

  • An 8mm Allen key

  • A bracket remover

  • A 250mm wrench (a slightly smaller one can also work)

  • A crank puller

These tools are vital for effectively removing and replacing the cadence sensor in your GIN X E-Bike.

Step-by-Step guide to cadence sensor removal


  1. Removing the Crank Arms: Begin by removing the left-hand side of the crank arm. To do this, you’ll need to remove the bolt from the crank arm. Remember, it has to be turned anti-clockwise. Once loose, the bolt can be taken out.

  2. Identifying and Removing the Cadence Sensor: Once the crank arms are removed, you’ll be able to access the cadence sensor. This component is located near the pedals and includes felt magnets and a sensor that lights up when the bike is switched on. Carefully remove the sensor and magnets.

  3. Cleaning and Reattaching the Cadence Sensor: It’s common for the sensor area to get dirty, so take this opportunity to clean it before reattaching the sensor. Make sure the sensor's 'A' side faces outward and the arrows face inward during reinstallation.




Reassembling the bike after cadence sensor removal


  1. Attaching the Crank Arms: When putting the crank arms back on, ensure they are correctly aligned – the right-hand side arm should be upward, and the left-hand side arm should be downward, making a 180-degree angle.

  2. Tightening and Final Checks: Use your wrench to tighten the crank arms fully. Remember, the recommended torque pressure on the bolt is around 50 Newton meters. Finally, switch on the bike to ensure the cadence sensor is functioning correctly – a blinking light will indicate proper operation.


How does a cadence sensor work?


A cadence sensor on an electric bike is a device that measures the rate at which a cyclist is pedaling. It typically works as follows:

  1. Detection of Pedal Rotation: The sensor is usually mounted near the bike's cranks and detects how fast the pedals are being turned. It often uses magnets attached to the cranks and a sensor fixed to the frame.

  2. Measurement: As the crank rotates, the magnets pass by the sensor. Each time a magnet passes, the sensor detects it and sends a signal. The frequency of these signals corresponds to the pedaling speed or cadence.


How does a cadence sensor work

  1. Data Transmission: This data is then transmitted to the bike's computer system or display. It's usually expressed in revolutions per minute (RPM), indicating how fast the rider is pedaling.

  2. Assist Adjustment: In electric bikes, this information can be used to adjust the level of assist provided by the motor. For instance, if the cadence is high, the bike may provide less assist, and vice versa.

In summary, a cadence sensor helps in monitoring and optimizing a cyclist's pedaling effort, especially in electric bikes where it contributes to the efficiency and effectiveness of the motor assist.


Conclusion


Removing and reattaching the bike cadence sensor on your GIN X E-Bike is a straightforward process, provided you have the correct tools and follow these steps carefully. Regular maintenance of your e-bike not only prolongs its life but also enhances your riding experience.


Tips and Reminders


  • Always handle bike parts gently to avoid damage.

  • Ensure that everything is properly tightened and aligned during reassembly.

  • Regular maintenance is key to the longevity and performance of your e-bike.
