This can feel much more natural than a bike with a cadence sensor, as it replicates the feeling of riding that many of us are used to and simply amplifies your efforts. Pedal hard and you’ll get maximum assist. Back off your intensity, and the assistance system will do likewise. Torque sensors can also be more efficient than cadence sensors, as the power delivered is based on the actual effort you put into the pedals and updates in real time. This efficiency can often mean you can eke extra miles out of a battery charge.
