1. A concealed bicycle lock system, comprising:
a connector, comprising:
a side plate;
a substrate, disposed on an inner side of a lower end of the side plate, wherein the substrate is disposed with a securing hole; and
a cantilever, disposed on an outer side of an upper end of the side plate, wherein the cantilever is configured to restrict a displacement of a head tube of a bicycle relative to a fork tube in a direction vertical to a diameter direction of the head tube;
a fastener, configured to secure the substrate of the connector to inside of the fork tube of the bicycle through the securing hole; and
a lock, comprising an upper shaft and a lower shaft, wherein the lower shaft comprises an expansion mechanism;
wherein when the substrate is fixed into the fork tube by the fastener, the side plate covers a part of an inner side wall of the fork tube, and when the expansion mechanism expands, the expansion mechanism abuts against and is fixed to another part of the inner side wall that is not covered by the side plate.
