More Responsive with Torque Sensors
Torque sensors change the motor's power based on how hard you pedal, so this feels much more natural than a bike with a cadence sensor. Pedal hard, and you get maximum boost. Reduce the intensity, and the boost system will reduce the intensity accordingly—no more ghost-pedaling. Torque sensors are also more efficient than cadence sensors, adjusting power based on rider effort to enhance control and conserve battery for extended range.
