Torque Sensors (weight 1.5kg)

A pedal sensor for measuring the amount of force which is being exerted on the pedals. It has an output which matches common throttle connections on controllers of 1 to 4 volts, the input voltage it runs off is 5volts (same as most standard controllers and crystalyte controllers).

Pedalling harder means more motor power is automatically applied. I would recommend using these with a normal throttle so in emergency situations you still have throttle control via the handlebar throttle.

Pictures below of pedal torque sensor:
left hand picture shows the right hand pedal crank and sproket, right hand picture shows the rear of the sprocket where the torque sensing unit is located, it uses a hall sensor to vary the output depending on how hard your pedalling, so can be used in place of a handlebar throttle.

Picture below shows the left hand crank just placed on top of the sprocket (not joined to it!) .The sensing unit (right hand crank) and left hand pedal crank replace your normal pedal cranks and sprocket.



Wiring Diagram:
Torque sensor could be used alone or with a standard handlebar throttle as shown below.
Torque sensor has 3 wires: red=5v power, black= ground (0v) and brown=output (1-4volts)
