1. A rear hydraulic braking system for a bicycle, the rear hydraulic braking system comprising:
a rear brake assembly operatively coupled to a first end of a first hydraulic tubing, the rear brake assembly comprising a first brake pad and a second brake pad, the first brake pad disposed on a first side of a rear brake surface of a rear wheel, and the second brake pad disposed on a second side of the rear brake surface opposite the first side, wherein the first brake pad and the second brake pad are configured to releasably engage the rear brake surface to slow a rotation of the rear wheel;
a rear brake lever operatively coupled to a second end of the first hydraulic tubing, wherein actuation of the rear brake lever is configured to actuate the rear brake assembly;
a hydraulic actuator comprising a cylinder and a piston rotatably coupled to the rear brake assembly, the cylinder configured to hold a hydraulic fluid, and the piston configured to slide within the cylinder to compress the hydraulic fluid; and
a second hydraulic tubing fluidically coupled to the cylinder, the second hydraulic tubing configured to direct compressed hydraulic fluid from the cylinder to a front brake assembly to actuate the front brake assembly to slow a rotation of a front wheel;
wherein the rear brake assembly, when actuated, is configured to move with a rotation of the rear brake surface to move the piston within the cylinder to urge the hydraulic fluid to flow through the second hydraulic tubing to actuate the front brake assembly to slow the rotation of the front wheel.
