e-bicycle torque intelligent sensor(known as pas \torque sensor\1:1 power-assisted).it is a high-tech component designed for electric bicycle with ergonomics,it has superiority to match well with all electric bicycles avaliable in the market ,it employs the dual -magnetic loop-hall elastic angle difference to detect the dynamic torque,which is converted to DC signal through special digital signal chip and then transform to the controller.
furthermore ,as a professional PAS manufacture ,facing to various kinds of e-bicycles and customers needs,we developed a special tool which called-setup device,it can adjust 8 different parameters of the PAS system to meet different requirements; and it can be used by customers following the operational manual.

features:
1.high universality:applicable to brush /brushless controller,high/low/sensor/sensorless motor-electrical system,24v/36v power system.
2.facility to install:install as the normal chain whel crank in bicycles,apply to ordinary bicycle d-type B.B parts.
3.three levels power adjusting function:it has three assistant power levels and the battery will be displayed on a dashboard.
4.riding on comfortably:large linear torque range with great stability and you will feel more soft when the gear changes.
5.well acclimatization:it has excellent anti-jamming ability that can work as normal in dirty water.
6.speed limitation:it can set a maximum speed transmission ratio(such as :25km/h power cut).
