A signal input unit (radio wave, cable, etc.) (FIG. 6) to reach, and a signal output unit (radio wave, cable, etc.) (FIG. 6) for transmitting a command to the user to perform a command through the control unit 120; There is a power supply section (internal battery, external power supply line) (Fig. 6) that enables the use of the terminal (Fig. 2).

When the user inputs a desired bar through the terminal (FIG. 2) through the input buttons 132 and 133, the command is transmitted to the output unit 130 through the control unit 120. It is transmitted to the derailleur and other transmission means to operate it so that the bicycle is shifted to the right stage at the most appropriate time, which helps the user to move comfortably and extend the life of the bicycle.

Since the transmission of the conventional bicycle is a mechanical type, the shifting operation performed by the user while driving the bicycle is performed intuitively instead of the data, and thus it is difficult to shift to the proper stage at the appropriate time. Stress was also increased.

In order to help the cyclist run smoothly, the current driving speed of the bicycle and the shifting stage suitable for the speed are indicated.The automatic shift mode that allows the bicycle to shift itself when driving as desired by the user, and the user judges at that time A manual shift mode for shifting is adopted, and for this purpose, a control unit has a built-in terminal and shifting means (a derailleur, etc.) for shifting.

In order to achieve the above object, a terminal (FIG. 2) made of various electromagnetic plates is installed, and the terminal has an input unit 110 for registering various kinds of information. 132 and 133), a sensing sense and a permanent magnet necessary for calculating the driving speed of the bicycle, and a signal input line which is a passage through which the detected information is input.
