Abstract
A bicycle shift control apparatus comprises a threshold value setting unit that sets a threshold value of a running condition for shifting a bicycle transmission, a decision unit that decides if a current running condition value passes the threshold value, and a tentative shift unit that sets a tentative shift of the bicycle transmission when the decision unit decides that the current running condition value passes the threshold value. A canceling unit cancels the tentative shift if the decision unit decides that the current running condition value varies from a previous running condition value by a determined value.
