    • A bicycle antitheft device includes an antitheft mechanism switchable between an antitheft state and a release state, wherein the antitheft mechamism includes a first member that moves relative to a second member to move the bicycle forward and backward. A movement controlling mechanism hinders the first member from moving relative to the second member when the antitheft mechanism is in the antitheft state, and a selection mechanism is provided for selecting one of the antitheft state and the release state. Alternatively, the antitheft mechanism may include a sound generator for generating a sound when the first member moves relative to the second member and the antitheft mechanism is in the antitheft state. The movement controlling mechanism and the sound generator may be combined into a single antitheft mechanism. The movement controlling mechanism and/or sound generator may be installed inside of an internal transmission such as a hub or crank transmission, or they could be installed inside a handlebar control for the transmission.
    • 一种自行车防盗装置包括可在防盗状态和释放状态之间切换的防盗机构,其中防盗机构包括相对于第二构件移动的第一构件以使自行车向前和向后移动。 当防盗机构处于防盗状态时,移动控制机构阻止第一构件相对于第二构件移动,并且提供选择机构用于选择防盗状态和释放状态之一。 或者,防盗机构可以包括用于当第一构件相对于第二构件移动并且防盗机构处于防盗状态时产生声音的声音发生器。 运动控制机构和声音发生器可以组合成单个防盗机构。 运动控制机构和/或声音发生器可以安装在诸如轮毂或曲柄传动装置的内部传动装置的内部,或者它们可以安装在用于变速器的车把控制中。
