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 available in the market . it employs the dual-magnetic loop-hall elactic 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 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)
