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.
When riding uphill or in complex terrain, the extra traction is helpful. The torque sensor handles the abrupt changes in speed and elevation well and never feels like it's going to take off on you when you don't want it to. The need to pedal harder to activate more auxiliary functions may be a downside for those who like to ride leisurely. What sensor you choose ultimately depends on your personal riding preferences. If you prefer a traditional cycling bike experience and can live with the higher price tag, then a torque sensor is a good choice for you. If you prioritize consistent assistance and a more affordable option, then a cadence sensor is better for you.
