The firmware is the core of the motor, the intelligence that processes the signals from the sensors (cadence sensor, torque sensor, and speed sensor) and converts them into smooth and responsive motor control, ensuring a natural riding experience.
As part of its ongoing commitment to innovation, Polini Motori continuously updates the motor firmware, allowing users to benefit from improved performance and control even after purchasing the product.
