E-bicycle Torque intelligent Sensor (Know 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 available 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 teansform to the controller .
Furthermore, as a professional PAS manufacture, facing to various kinds of e-bicycles and customers needs, we developed a special tool with 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 wheel 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)
