E-bicycle Torque Intelligent Sensor(known as PAS\torque sensor\1:1 power-assiated).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 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.
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 poer adjusting function :it has three assistant power levels and the battery will be displayed on a dashboard.
4.riding on comfortaly: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).
