Data display instrument for a bicycle

Abstract

The data display instrument for a bicycle comprises an LCD field having an analog scale field to display the momentary travelling speed and an analog scale field to display the pedalling speed. The scale fields are automatically switchable to two measuring ranges. Furthermore, two digital numerical fields are provided in which a multiplicity of information concerning the riding situation can be displayed in dependence on the travelling speed. In addition to the momentary speed and the momentary pedalling speed which are displayed in the scale fields, the digital fields will during travel display the distance travelled since a last reset and the average speed. Immediately after the bicycle comes to a standstill, the digital fields will indicate the travelling time since the last reset and the maximum speed. After a predetermined period of time has elapsed during which the bicycle continues to remain immobile, the digital fields will indicate the total distance travelled and the wheel diameter. For switchover between individual operating modes, a single operating key is provided which switches over the operating modes as the result of short or medium or prolonged actuation and which can erase the memories for distance travelled since the last reset, average speed, travelling time since the last reset and maximum speed, or set the instrument to an operating mode for programming the wheel diameter. The data display instrument facilitates reading of the data and so makes a contribution to cycling safety.
