Abstract
An apparatus for informing a rider of an upcoming shifting operation in a bicycle transmission includes a running condition detecting mechanism that detects a running condition of the bicycle, a control mechanism that provides a signal that commands the shifting operation when the running condition reaches a threshold value, and a warning mechanism that warns the rider when the running condition approaches the threshold value.
