6. ഓപ്പറേഷൻ
The Bafang torque sensor provides a natural and intuitive pedal assist experience. It measures the force you apply to the pedals and signals the e-bike motor to provide assistance proportionally. The harder you pedal, the more assistance the motor provides, making your ride feel more like a traditional bicycle but with added power.
- Pedal Engagement: The assist system will engage as soon as you start pedaling and apply force.
- സഹായ നില: The level of assistance can typically be adjusted via your e-bike's display unit, allowing you to customize your riding experience.
- വിച്ഛേദിക്കൽ: The assist will disengage when you stop pedaling or apply the brakes.
7. പരിപാലനം
Regular maintenance helps ensure the longevity and optimal performance of your torque sensor:
- വൃത്തിയാക്കൽ: Keep the sensor and surrounding bottom bracket area clean from dirt, mud, and debris. Use a damp cloth for cleaning; avoid high-pressure water jets directly on the sensor.
- കണക്ഷൻ പരിശോധന: Periodically inspect all electrical connections for corrosion or looseness. Ensure they are securely fastened.
- ടോർക്ക് പരിശോധന: Occasionally check the tightness of the bottom bracket retaining rings to ensure they remain at the specified 40 N.m torque.
- നാശനഷ്ട പരിശോധന: Visually inspect the sensor and its wiring for any signs of physical damage, cracks, or frayed wires.
8. പ്രശ്നപരിഹാരം
If you encounter issues with your torque sensor, consider the following:
