The invention discloses a manual-moving type variable speed controller of a bicycle. The manual-moving type variable speed controller of the bicycle comprises a push rod, a fixed base plate, a main winding member, a gear shift positioning unit, a first bearing, a second bearing, a first fastener, a first turning spring, a second turning spring, a spring and a gear bolt. The gear shift positioning unit comprises a gear shift rod, positioning teeth, a fixing pin, a second fastener, a third turning spring and a fourth turning spring. The main winding member is integrated for reducing errors produced in a traditional manufacturing and assembly process of the main winding member and improving the accuracy of speed change gear shift positioning and is provided with double rows of gears for effectively solving the deficiency that both sides of one row of gears are stressed in the prior art. The push rod is designed for greatly improving the accuracy of gear shift and also improving the safety factor. Meanwhile, the problem of abrasion of parts is well solved by replacing traditional grease with Teflon.
