Reference Structural Drawing:
ou should make sure the size of your Bottom bracket is 68mm:
Usually most of the regular bike's size is 68mm.
What is torque sensor and what is the strength?
Torque sensor means the motor works as long as there is strength on the pedal.
The speed sensor means the motor will work only when the pedal move.
Which makes a big difference on hilling, when you face a high mounting, you can even not make the pedal move, so the speed sensor wont work , but if you are with the torque sensor, the motor will runs without any problem.
In one word, this torque sensor system is very good at hilling/mounting.
