With the development of the bicycle industry, an electronic speed changing system is derived from a bicycle speed changing system on the basis of a traditional mechanical speed changing system, and with the gradual maturity of the technology of the electronic speed changing system, the electronic speed changing system is widely pursued in recent years. Compared with a mechanical speed change system, the electronic speed change system is more stable in operation and more convenient to operate, and for a speed change controller in the speed change system, the structure of the electronic speed change controller is far simpler than that of the mechanical speed change controller. For example, the electronic speed change controller can control the electronic derailleur to shift the chain to switch positions only through electrical cooperation between electronic elements on the electronic speed change controller, so that speed change is realized; the mechanical speed-changing controller needs to make the wire spool drag the speed-changing wire through the complex linkage coordination among the parts such as gears, pawls and the like in the mechanical speed-changing controller, so that the speed-changing wire drives the mechanical derailleur to shift the chain to move. It can be seen that when the number of switchable gears of the mechanical speed-change controller is larger, the structure is more complicated, the reliability is lower, and the speed-change cable is easy to fatigue and break after being repeatedly wound and released, while the electronic speed-change controller does not have the above problems, and the corresponding speed of the electronic speed-change controller to the operation of the rider is faster.
However, the existing electronic shift controllers have the following disadvantages: the position layout of the shift levers and the reverse levers for controlling the electronic derailleur is not reasonable, resulting in a troublesome gear shifting operation of the electronic transmission system and being prone to errors. In addition, only one shift lever is provided on some conventional electronic shift controllers, so that when the front electronic derailleur and/or the rear electronic derailleur are/is controlled, the shift lever of the left electronic shift controller and the shift lever of the right electronic shift controller need to be logically controlled to enable the front electronic derailleur and/or the rear electronic derailleur to perform corresponding shifting actions.
