PROBLEM TO BE SOLVED: To provide a bicycle transmission device capable of improving detection accuracy of an inclination angle of a road surface, a bicycle transmission control device for controlling the transmission device, and a transmission control system of a bicycle having a transmission.SOLUTION: A bicycle transmission device 52 comprises a transmission 58 for changing a transmission ratio of a bicycle, and an inclination sensor 60 provided in the transmission 58 for outputting a signal reflecting the posture of the transmission 58. The transmission device calculates an inclination angle of a road surface based on an output of a bicycle speed sensor 78 and performs optimum transmission control according to the inclination angle of the road surface by controlling the transmission 58 on the basis of information of a rotation detection sensor 86 for detecting crank rotation of a pedal.SELECTED DRAWING: Figure 3
