The speed and torque of the pedals are individually controlled by setting a preferred cadence and load. The cadence has priority: If you pedal slower or faster than the ideal cadence the algorithm will try to keep your ideal cadence by changing load. This is implemented by simulating a standard bicycle gear change so you will experience a step change in load. However, the number of “gears” and the delay before changing “gears” might be adjustable. Also, the pedal load reflects the wheel load so that it becomes easier to pedal when you pass a top and start going downhill.
