To avoid misconceptions, it's important to clarify that even the most advanced automatic bicycle shifting systems shift reactively, not predictively. These systems respond to changes in certain parameters in real time, within a fraction of a second. For (e-)mountain biking on technical terrain, automatic shifting cannot match the decision-making of a human rider. However, the ability to quickly and accurately execute manual shifts in challenging conditions is crucial, and this is where the Pinion Motor.Gearbox.Unit excels with its near-instant gear changes.
