E-bicycle torque intelligent sensor(known as pas\torque sensor \1:1 power-assisted )it is a high-thch 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 convered to DC signal through apecial 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 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 mormal in dirty water.

6.Speed limitation:it can set a maximum speed transmission ratio(such as :25km/h power cut).
