These and other features and characteristics of the present invention are further illustrated by the following statements:

• Indicators on a bicycle are usually attached to the handlebars today.

It is often complex to protect these displays against mechanical dangers, weather influences etc. In addition, there is the problem that mounting the display has a negative impact on the design of the wheel. Added to this is the elaborate bracket, the wiring, etc. Furthermore, it is difficult to protect the display against theft and vandalism.

Since rectangular displays are typically used for the advertisements for cost reasons, the impression of a foreign body is intensified. An adjustment of the display geometry would be desirable, however, because of the variety of shapes of bicycle handlebars and stems, inexpensive production in large series cannot be achieved.

It is therefore desirable to have a mechanically robust solution that is optimally adapted to the conditions of a bicycle stem and that can also be manufactured inexpensively.

• - mechanisch robust,
• - optimal in den Fahrradvorbau 4 integrierbar und
• - kostengünstig an jeden Lenker 2 und an jedes Lenkrohr 3 anpassbar ist
