Abstract:
The present application relates to the technical field of bicycles. Disclosed are a bicycle hydraulic brake control device and a bicycle. The bicycle hydraulic brake control device comprises: a control main body connected to a handlebar of a bicycle; a brake lever pivotally connected to the end of the control main body that is away from the handlebar by means of a first pivot; a hydraulic cylinder connected to the interior of the control main body; a piston rod having one end movably arranged in the hydraulic cylinder and the other end extending out of one end of the hydraulic cylinder; and a trigger member hinged to the interior of the control main body and located on one side of the hydraulic cylinder, wherein the trigger member comprises a pressing portion and a pushing portion which are connected to each other at a preset angle, one end of the pressing portion abuts against an inner wall of the brake lever, and one end of the pushing portion is connected to one end of the piston rod by means of a rolling member. In the brake control device, the piston rod is pushed by means of the rolling member to do a piston motion, so that hard friction between the trigger member and the piston rod is prevented to reduce the friction force between the trigger member and the piston rod and achieve a smooth hand feeling of braking, the braking effect is improved, and a rider's braking experience also improved.
