ABSTRACT:
A display apparatus for a bicycle having a speed changer includes a display (10) switchable between a running mode for displaying running information such as time, running speed or running distance, and a shifting mode for displaying shifting information such as a speed stage of the speed changer; a switch and sensors (7a, 7b, 17) for generating a command to switch the display from the running mode to the shifting mode; and an automatic mode change device (12a, 12f) for automatically switching the display from the shifting mode to the running mode. The automatic mode change device includes a control unit (12a) and a timer (12f). The control unit transmits the shifting information in place of the running information to the display device in response to a signal from the sensor or switch. The timer starts measuring time in response to the signal from the sensor or switch. Upon lapse of a predetermined time (t), the control unit transmits the running information in place of the shifting information to the display.
