A method for immobilizing a vehicle, in particular an electric bicycle. A drive train of the vehicle includes a clutch that includes a first clutch component and a second clutch component that are situated coaxially with respect to one another and configured to be rotatably fixedly connected to one another by mechanical contact in at least one predefined rotational direction. The method includes: detecting an input of a user for activating an immobilizer, and actuating an actuator as a function of the detected input, as the result of which the first clutch component and/or the second clutch component are/is displaced in the axial direction, as the result of which the mechanical contact between the first clutch component and the second clutch component is separated.

A system and method for detachably locking an apparatus onto a bicycle chain to prevent rotation of the chain over the sprocket and thereby prevent theft of the bicycle.

A bicycle lock has a lock casing, a lock core assembly, a lock bar, and a lock cable. The lock casing has a front end surface, a back end surface, a peripheral surface, an installation slot, a fixed pin, a lock core recess, and a cable slot. The installation slot is recessed from the peripheral surface. The fixed pin is secured in the installation slot. The lock core recess is recessed from the front end surface. The lock core assembly is movably mounted in the lock core recess. The lock bar is connected to the lock core assembly and is capable of moving into the installation slot. The lock cable is detachably mounted in the cable slot of the lock casing. The bicycle lock can be fixed on a chain of a bicycle to interfere with operation of the chain, thereby preventing theft

A lock and a bicycle are provided. The lock includes a power source, a driving block, a driven assembly and an elastic transmission. The driving block is connected to the power source in a transmission manner. The driving block is capable of moving between a first position and a second position under drive of the power source. The driven assembly includes a driven block and a latching tongue connected to each other, and the driven assembly is capable of moving between a locking position and an unlocking position. The elastic transmission component is connected between the driving block and the driven block in a transmission manner, and when the driving block is disposed on the second position, the elastic transmission component has a tendency to drive the driven assembly to move to the locking position.
