High precision speed sensor

Price FreeDisk diameter 6cmOutput interface Four wire systemStart angle Pedal>30ºCut-off interval After 75ms when the pedal stopsMinimum temperature Won’t turn brittle below -50 deg. centigradeMaximum temperature Won’t be out of shape above 80 deg. centigrade

The global original high-precision speed sensor and innovated algorithm of software make peoplevery comfortable when they are ridding the electric bicycle. During the rider pedaling, the motorwill neither drive less nor drive more, so the speed by motor propelling is almost the same speedof pedaling. The driving speed is regulated by controller once one hundred milliseconds. The riderneither feels difficult nor pedaling emptily, so our SSP( Speed Sensor PAS) works outstandinglyas same as TSP( Torque Sensor PAS) on the lever road.
