ABSTRACT:
A bicycle antitheft device includes an antitheft mechanism switchable between an antitheft state and a release state, wherein the antitheft mechanism 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.
