Abstract
The control system of the present disclosure is particularly designed for use in the bicycle which is so designed as to change gears upon shifting of a chain guiding mechanism. The control system includes a motor driven reel, a flexible wire connected between the reel and the chain guiding mechanism and a switch arrangement for controlling the rotation of the reel. Upon turning on of the switch arrangement, the motor is rotated by a predetermined amount to perform a suitable shifting operation of the chain to engage with a required gear.
