A bike pedal sensor helps track your e-bike’s performance and assists with electric motor engagement. You can install it by carefully mounting the sensor near the pedal cranks, connecting the wire harness, and calibrating it with your e-bike’s control system.
Electric bikes have transformed personal transportation, offering an eco-friendly and efficient way to travel. Among the most critical components of an e-bike is the pedal sensor, which acts as the bridge between human power and electric assistance.
What is a Bike Pedal Sensor?
A bike pedal sensor detects your pedaling motion and tells the electric motor when to provide assistance. This smart device monitors your cycling effort, ensuring smooth and efficient power delivery.
Types of Bike Pedal Sensors
1. Cadence Sensors
- Tracks pedal rotation speed
- Helps measure cycling rhythm
- Provides basic performance data
2. Torque Sensors
- Measures actual pedaling force
- Delivers precise electric motor assistance
- More advanced and expensive option
3. Magnetic Pedal Sensors
- Uses magnetic field to detect pedaling
- Highly accurate
- Works well in various weather conditions
