1.The torque intelligent sensor can make the rider and the bicycles the one,it could assistant as the rider's need,and adjustor itself according the condition of the road,especially when climbing.
2.when climbing ,the assistant system will privide powerfui force and make the climb like on the flat,whatever the gradient.
3.prolong battery life-span:half of the output power can avoid the damage of the high-power output bring on the battery.Also it can reduce the power automatically when the speed is increasing,At the same time,the mileage can be increased twice or more.
4.Good security:the system can turn off the power at once (within 2ms)after stop pedaling,The e-bicycle move on and slide just by the right of inertia,so the rider can control the e-bicycle like the bicycle.
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 assitant 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.
