Abstract
Stationary training bicycle having a pedal crank mechanism coupled to a transmission by a flywheel. A magnetic braking device interacts with the flywheel and is variable in its braking action. A calibration table stored in a computing device contains a plurality of braking device settings with reference rundown times of the flywheel not loaded via the pedal crank mechanism and relating to the speed reduction from a first speed to a second speed. The actual rundown time of the flywheel is ascertained at least once by means of a measuring device or the computing device and compared to the reference rundown times. If actual setting and target setting do not correspond, information relating to the actual setting can be output on the display device.

Stationary training bicycle, comprising;
- a pedal crank mechanism, which is coupled via a transmission to a flywheel,
- a magnetic braking device, which interacts with the flywheel and is variable in its braking action, and
- a computing device having assigned display device, wherein a calibration table is stored in the computing device, containing a plurality of defined braking device settings, to which reference rundown times of the flywheel, which is not loaded via the pedal crank mechanism, relating to the speed reduction from a first speed to a second speed are assigned,
- wherein for the calibration the actual rundown time of the flywheel at a given target setting of the braking device is ascertained at least once by means of a measuring device or the computing device and, on the basis of the measured actual rundown time, by comparison to the reference rundown times, the actual setting of the braking device specific for the rundown time is determined and, if actual setting and target setting do not correspond, information relating to the actual setting can be output on the display device, and
- wherein power values that a training person has to apply for defined brake device settings and defined rotational speeds to drive the flywheel are stored in the calibration table and the computing device is configured to automatically determine an instantaneous applied power as a function of a currently selected brake device setting and a current rotational speed based on the stored power values.
Method for calibrating the power display, which can be ascertained by means of a computing device, of a stationary training bicycle, wherein a calibration table is stored in the computing device, containing a plurality of defined braking device settings, t which reference rundown times of the flywheel, which is not loaded via the pedal crank mechanism, relating to the speed reduction from a defined first speed to a defined second speed are assigned, in which method a user, at a provided target setting of the braking device, at least once drives the flywheel via the pedal crank mechanism of the training bicycle with continuous speed ascertainment to a speed which at least corresponds to the first speed, after which the actuation of the pedal crank mechanism is ended and, by means of a measuring device or the computing device, the actual rundown time, which the flywheel requires for a drop from the first speed to the second speed, is measured, after which, on the basis of the measured actual rundown time, by comparison to the reference rundown times, the actual setting of the braking device is ascertained and, if actual setting and target setting do not correspond, information relating to the actual setting can be output on the display device, wherein power values that the user has to apply for defined brake device settings and defined rotational speeds to drive the flywheel are stored in the calibration table and the computing device is configured to automatically determine an instantaneous applied power as a function of a currents selected brake device setting a current rotational speed based on the stored power values.
