Abstract: The present invention relates to an apparatus for setting the wheel size of a bicycle (1, 2) on a bicycle computer (3) using input means (4, 5) on the bicycle computer (3). The aim is to be able to set the bicycle computer to the correct wheel size in a simpler and more reliable, virtually automatic, manner. This is achieved in that the bicycle computer (3) has at least two input means (4, 5) for at least two wheel sizes, in that a transmission means (6, 7), which can be assigned to the bicycle (1, 2), is provided for transmitting the wheel size of the bicycle (1, 2), and in that the transmission means (6, 7) interacts exclusively with that input means (4, 5) of the bicycle computer (3) which corresponds to the wheel size of the bicycle (1, 2).

Abstract: A data transfer device for a bicycle computer or the like, comprising data transmission means (3), a data processing device for the collection of data according to the selection of a function corresponding to a particular criterion and input of a value, input means (5), selection means (6) and a display device (7). The invention further relates to a computer for a bicycle, inline skates or a walking stick or similar and a method using the data transfer device. An object of the invention is to be able to rapidly set and/or update a bicycle computer according to the requirements of the user. In contrast to the state of the art the bicycle computer (2), or the like, which is difficult to set is not programmed, but rather a data transfer device (1), by means of which the data, after input and selection is then transmitted to the bicycle computer (2), or similar by a contact or by the transceiver principle (8, 9).
