Sensor

For Precise Pedal Assist

Hyena provides a series of sensors measuring the applied pedaling of the rider, delivering precise and accurate torque and cadence signals to the e-bike controller. Based on this information, our advanced firmware algorithm builds a perfect link between the rider’s pedaling behavior with the drive system.

These measured signals are sent to the control unit, where they undergo intelligent and bionical processing, allowing the Pedal Assist System (PAS) to be finely tuned to amplify the rider’s effort. Our system is designed to work in harmony with the rider, enhancing the cycling experience with each pedal stroke and promoting an efficient, natural ride that feels like an extension of the cyclist’s capabilities.
