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.
