Abstract:
Controlling automatic gear-changing of an electric gear-change apparatus of a bicycle, the method may involve assigning each of a plurality of gears of the bicycle a predetermined gearing range. Controlling the process may also involve assigning a predetermined lower limit value and a predetermined upper limit value to each gearing range, wherein the upper limit value of a gearing range is in each case larger by a predetermined value than the lower limit value of a next higher gearing range, and the upper limit value of the gearing range and the lower limit value of the next higher gearing range define between them an overlap range. Controlling the process may also involve selecting an engagement of either a gear or a next higher gear in the overlap range depending on a speed profile of the bicycle.
