Left Dual Hall Sensor for Electric Bicycle Pedal Assist

This Left Dual Hall Sensor for Electric Bicycle Pedal Assist is a crucial electronic component designed to restore reliable pedal assist functionality to your electric bicycle. It is intended as a direct replacement for worn or damaged sensors, ensuring your e-bike's pedal-assist system operates correctly.

Compatibility and Installation Checks

To ensure correct fit and function, it is essential to compare this sensor with your existing part before ordering. Compatibility depends on several factors:

  • Side: This is a left-side sensor. Ensure your replacement requires a left-side unit.
  • Dimensions: Carefully compare the overall dimensions (height, width, thickness) and especially the inner diameter (14.5 mm) with your existing sensor and the space available on your bicycle's bottom bracket area.
  • Connector Type: Verify that the 3-pin male connector (with red, green, and blue wires) matches the connector on your e-bike's wiring harness.
  • Mounting: Observe the mounting points and design of your current sensor to confirm this unit's shape and attachment method are compatible.
  • Markings: Check for any model numbers or markings on your original sensor, such as "SL-12," to help confirm compatibility.

Incorrect installation or incompatible parts can lead to system malfunction or damage. If you are unsure about the installation process or compatibility, professional assistance is recommended.
