1. A method for monitoring the travel speed of a bicycle, comprising the following steps:
in a sensor-power-supply period, providing a power supply for a first speed sensor that, when powered, transmits sensor signals in response to sensor trigger events;
ascertaining a first speed for the bicycle based on the sensor signals transmitted in the sensor-power-supply period;
in a first instance of a sensor-power-suppression period that immediately follows the sensor-power-supply period:
interrupting the power supply for the first speed sensor, thereby preventing transmission of additional sensor signals by the first speed sensor for an entirety of the first instance of the sensor-power-suppression period, which has a first predefined interruption time duration; and
ascertaining a second speed using a second speed sensor,
ascertaining a comparison result by comparing the ascertained first speed and the ascertained second speed; and
recognizing the first speed sensor as faulty as a function of the comparison result.
