Abstract

This invention discloses a braking force enhancement structure and a bicycle using the same. The braking force enhancement structure includes a piston chamber and a piston assembly. The piston assembly is movably disposed within the piston chamber and divides the piston chamber into a front space and a rear space, wherein the front space and the rear space are located at the front and rear ends of the piston assembly, respectively. A hydraulic passage is provided on the side of the piston chamber, and the two ends of the hydraulic passage are connected to the front space and the rear space, respectively. When the piston assembly moves towards the front space, the front space connects with the rear space, and the hydraulic oil in the front space flows to the rear space through the hydraulic passage. The hydraulic passage in this invention, with its two ends connected to the front and rear spaces, significantly improves the braking force of the bicycle brake lever without changing the brake lever travel or the area of ​​the launching piston.
