Handlebar control device for bicycles, bicycle hub, and antitheft system connecting the aforementioned devices

摘要

The handle control device for bicycles restricts the rotation of the front fork being rotably supported on a head tube of a bicycle frame, and comprises a rotable member, a stationary member, a rotation restriction means, and a locking means. The rotable member rotates coupled to the front fork, and the stationary member is provided non-rotably at the head tube. The rotation restriction means has an operating element which is movable between the position of restriction and the position at which the restriction is released (restriction release position) and restricts the relative rotation of the rotable member and stationary member at the position of restriction and releases this restriction at restriction release position. The locking means comprises a lock with an attachable and detachable key and a rocking element movable by said key, and a movable element that is movable coupled to the movement of the rocking movement, and locks aforementioned operating element at the restriction position by action of the movable element when the operating element is located at said restriction position. <IMAGE>
