  • a combination of various such information such as the evaluation of a connection between torque information on a crank of the bicycle and acceleration information, is also possible for the evaluation and determination of the flight phase. If it is determined in the previous step that the bicycle is currently in a flight phase, a switching process of a switching device can be prevented.
  • Such a prevention can, for example, be the setting of a corresponding identifier, such as a corresponding flag in a memory, which instructs a switching device not to allow a switching process. However, this can also involve the failure to trigger a corresponding switching process despite a corresponding switching request from a user or despite a corresponding instruction from an automatic switching system.

In this case, the cancellation of the inhibition of the gear shifting process of the bicycle's gearshift device is carried out in step S3a.
  • step S3a a corresponding flag or a corresponding identifier is set in a memory, which indicates to a gearshift device on the bicycle that a gear shifting process can be carried out if this is requested by an automatic gearshift or the user. If, however, step S2 is carried out in the area between points A2 and A3, a flight phase is detected and then in step S3b a gear shifting process of a bicycle's gearshift device is inhibited. For this purpose, a corresponding flag or a corresponding identifier is again set in the memory. This identifier indicates to a gearshift device that, even if an automatic gearshift or the user requests the gear shifting process, the gearshift device must not be activated to carry out a gear change.
