polini SPEED SENSOR
Polini’s sensor range for the E-P3+ EVO and EVO2 systems has been developed to provide precise and reliable monitoring of riding parameters. This helps optimize motor response while improving control, smoothness, and overall performance in every riding condition.

Phonic Wheel Sensor
The Polini Phonic Wheel Sensor has been specifically developed for the last generation Polini E-P3+ EVO2 system.
Thanks to its high signal resolution, the system can react more quickly and consistently to speed variations, delivering:
- Smoother motor response
- Improved control during acceleration and deceleration phases
- Greater stability on uneven terrain, technical climbs and routes with frequent changes in riding rhythm
Integrated with the new E-P3+ EVO2 motor, the electronic Phonic Wheel sensor makes the Polini system more responsive, reliable and enhances the overall riding experience.
Magnet Sensor on the disc
Designed for the E-P3+ EVO system, this sensor offers improved integration with bicycle frames. It accurately detects the bicycle’s speed and transmits real-time data directly to the motor control unit.


Magnet sensor on the rays
This compact and durable sensor accurately detects the bicycle’s speed and transmits real-time data directly to the motor control unit, each time the magnet passes in front of the sensor
