PROBLEM TO BE SOLVED: To provide a bicycle speed-change control device to control a speed-change device for a bicycle having a plurality of speed-change stages devised to easily change switching operation of upshifting and downshifting. SOLUTION: This speed-change control device 110 to control a front derailluer 97f having a plurality of the speed-change stages is furnished with a front first switch 131f, a front second switch 132f, a switch connection changing part 130a and a speed-change control part 130b. The second switch is a switch arranged at a position different from that of the first switch. The switch connection changing part can change connection of the first switch and the second switch with upshifting motion and downshifting motion of the front derailluer. The speed-change control par shifts up the front derailluer when the switch related to the upshifting motion out of the first and second switches is switched on and shifts it down when the switch related to the downshifting motion is switched on.
