Abstract
A bicycle transmission control apparatus is provided that can perform a shift control according to the traveling environment of the bicycle. The bicycle transmission control apparatus includes a controller that operates a transmission according to a parameter that represents a traveling state of a bicycle and predetermined shifting conditions. The controller sets the predetermined shifting condition based on the parameter representing a running state of the bicycle and on a tilt angle of the bicycle.
