The present invention provides a back support for reinforcing a pedal-effort of a bicycle, which is an incidental device of the bicycle, comprising: a fixing support part coupled to a bicycle saddle mounted rod; and a back support higedly coupled to one end portion of the fixing support part so as to be rotated forward and backward by a predetermined angle, wherein the fixing support part is coupled to the saddle mounted rod through a fixing support part installation bracket, a rectangular pipe is connected to one side of the fixing support part installation bracket, and a spring is mounted between the back support and the fixing support part to adjust the inclined angle of the back support by the resilient force thereof. Therefore, it is possible to enhance convenience in pedal-effort reinforced driving. Further, a bicyclist can adjust the inclined angle of the back support while travelling to ride a bicycle while leaning against the back support, thereby enhancing comfort and convenience in the travelling. In addition, the rotational moment of the back support is transmitted to the rectangular pipe to prevent the rectangular pipe from being deflected or to prevent the inclined angle from being changed so that a bicyclist can increase a pedal effort by stretching out his/her leg while stably leaning against the back support, with the back support functioning as a support point. |
