The invention provides a bicycle suspension fork. A vertical headstock pipe is connected with a bicycle frame. The vertical headstock pipe is connected with a suspension fork body in a relatively rotating mode. The bicycle suspension fork comprises a vertical front fork pipe, a bibcock, a fork pipe assembly, a connection piece and a suspension system. The suspension system comprises a first spring and a second spring. The first spring is clamped between the bibcock and the fork pipe assembly and located in the vertical headstock pipe. The second spring is clamped between the lower end face of the vertical headstock pipe and a boss of a connection head. According to the bicycle suspension fork, when a front wheel passes through an uneven ground, the shaking force borne by the fork pipe assembly is absorbed through the second spring, action force applied on a riding person on the bicycle frame is lowered, the shaking force is absorbed by the first spring, the action force applied on the double arms of the riding person on a direction handle is lowered, the direction turning torque is transmitted in the mode that knurl gear rings are embedded, the synchronism is good, and assembling efficiency is high.
