A bicycle includes a frame and an electronic security device. The frame includes a hollow space and at least one opening. The hollow space is configured within the frame. The at least one opening is configured in the frame and the at least one opening is connected to the hollow space. The electronic security device is configured such that it is accommodated within the hollow space of the frame. The electronic security device includes a retractable locking shackle configured to assume a locked position and a retracted position by moving through the at least one opening configured in the frame. The locked position of the retractable locking shackle restricts a movement of a wheel of the bicycle and the retracted position enables free movement of the wheel of the bicycle.

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.

The present invention relates to a bicycle lock for blocking of a wheel of a bicycle in a locked state. The bicycle includes a tube assembly including a frame with mutually fixed tube elements and movable tube elements, such as a front stay. The bicycle includes a housing, a bolt for providing a blocking action in a blocking state with which the wheel is blockable, a channel for arranging therein of the bolt, and a latch for, in a latching state of the lock, keeping the latest in the blocking state. The latch in the blocking state is in cooperation with receiving means defining a state of cooperation in which the bolt and the receiving means block the wheel of the bicycle.

A tracking unit is for a human-powered vehicle having a frame and an electric gear shifter. The tracking unit has a tracker, such as a GPS and/or GSM unit, and an antenna for allowing the tracker to communicate. The tracker is adapted to be placed inside the frame of a human-powered vehicle, and includes a wire adapted to extend from the tracker, through a hole in the frame, to the antenna adapted to be mounted on the exterior of or at least partially integrated in the electric gear shifter.

An anti-theft device for a bicycle includes a fork unit that has a first fork bar and a second fork bar. The first fork bar has a passage and the second fork bar has a receiving opening. A securing element can be arranged in the fork unit to pass through the first fork bar in the passage and engage in the receiving opening. The securing element passes through a spoke region of a front wheel of the bicycle. The securing element has an engagement contour that engages in the receiving opening. A locking unit with an electromechanical drive is arranged in the second fork bar. The locking unit has a locking contour, which is connected the electromechanical drive and engages in the engagement contour in the locking state. An electronic control unit controls the electromechanical drive to unlock the unit.

Disclosed are an article use control method, device and system and an article. The article use control method includes: providing an article in an available state, the article having a unique article identifier; when detecting an event that the article is used by a user, starting up a timer to count down to wait for an article use authentication result based on the article identifier and a user identifier of the user who uses the article, the user identifier uniquely identifying the user; and when the article use authentication result is not acquired or the authentication is failed before the countdown ends, changing the article from the available state to a disabled state. According to the present invention, a user can use an article before performing an authentication operation. Moreover, during the use of the article by the user, article use authentication is completed in a user-unperceivable manner. The user experience is improved.

A locking system and an unlocking method for an electric bicycle are provided. The locking system of the electric bicycle includes a locking device, a rotational speed sensor, a torque sensor, and a controller. The rotational speed sensor senses rotation direction information of a crank arm of the electric bicycle. The torque sensor obtains torque information exerted by the crank arm on a chainring of the electric bicycle. The controller is coupled to the locking device, the rotational speed sensor and the torque sensor. In response to the locking device is being a locking state, the controller unlocks the locking device according to the rotation direction information and torque information.
