This feels much more natural than a bike with a cadence sensor, the intuitive torque sensor amplifies the cadence of yourpedaling efforts. 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 because the power provided is based on how hard you're actually pedaling and updates in real time. This efficiency usually means matching your natural rhythm to conserve battery life and extend range.
