A bicycle locking system for mounting in a bicycle including an axle which is rotatable around its longitudinal axis, a first locking element and a second locking element, which are configured for locking engagement with each other, where the first locking element is fixed to the axle and each of the first and second locking elements comprise an engagement surface. The locking system also includes a biasing device and an actuation element, the biasing device configured to exert a force on the second locking element in the longitudinal direction, so as to displace the first and second locking elements in relation to each other, where the biasing device is a magnetic biasing device, and the actuation element acts to switch the locking system between a state where the biasing device magnetically repels the second locking element and a state where the biasing device magnetically attracts the second locking element.

An apparatus and a method for bicycle anti-theft are provided. When a biometric feature of a user matches a preset biological feature, a brake lever is fixed at a preset position to lock the bicycle.

A multi-diameter clamp for clamping on tires of different sizes is provided. The multi-diameter clamp comprises at least one clamping unit, at least one actuator, and at least one sensing unit. The at least one clamping unit further includes at least one movable member and a fixed member. Wherein the at least one movable member moves within a tire housing space having a starting position and a clamping position. The tire housing space locates between the movable member and the fixed member for clamping on a tire. The at least one actuator connects to the at least one movable member, and enables the at least one moveable member to move between the starting position and the clamping position. The at least a sensing unit obtains a diameter size of the tire, and based on the diameter size, actuates the at least one actuator corresponding to the diameter size.

A rotary locking mechanism and a lock applying the rotary locking mechanism and a locking control method are provided. A rotary output member is locked by a stable triangular supporting structure between the first locking member and the second locking member, the effective constraint of the second locking member on the first locking member applied by the first locking member in both a locked state and an unlocked state achieves locking and unlocking reliability of the product. The entire locking mechanism is controlled by the same switching member. The false locking operation when the rotary member is operating is effectively avoided through the mechanical structure and the automatic control method. The entire rotary locking mechanism is enclosed and fixed in a shell of the lock, and can be applied to transmission machinery of bicycles, electric vehicles, motorcycles and even lightweight automobiles.

A hub lock includes a lock body fixedly mounted on a rear fork and a lock disc connected to the hub, the lock body includes a lock pin movable in a first direction between first and second critical positions, the lock disc has a lock slot and a guiding face capable of opposing the lock pin in the first direction, the lock pin is fitted in the lock slot at the first critical position, the lock pin is slidingly fitted to the guiding face during a movement from the second critical position towards the first critical position, the lock slot has first and second limiting faces opposite each other along a circumferential direction of the hub and both connected to the guiding face, a size of the first limiting face is greater than a size of the second limiting face in a depth direction of the lock slot.

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.
