Abstract: An alarm device for a bicycle includes a locking block and an alarm assembly connected with the locking block. The alarm assembly includes a base, a mounting seat, an alarm unit, a top cover, and a bottom cover. The alarm unit includes a circuit board, at least one sensor, at least one buzzer, a control switch button, at least one storage battery, an indication lamp, and at least one socket hole. When the alarm unit is started, the alarm unit detects vibration or shaking of the locking block or the alarm assembly due to an external force and transmits an alarm signal so as to achieve a burglar-proof effect.

Abstract: A bicycle tire cover includes an elongate body having two edges which are folded downward to form the body as a U-shaped cover. A connection portion includes a first connection member on the first end of the body, and a second connection member on the second end of the body. Two resilient portions are connected to each of the two edges respectively. The body is mounted to a tire, and the first and second connection portions connected to each other to secure the tire cover to the tire. The tire cover is easily mounted to the tire while the tire does not need to be removed from the bicycle frame.

Abstract: The invention relates to a cable lock, which consists of a lock body combined with a traversing part, wherein a slider and a holder are set inside the lock body, at least an upper bead hole is set on the slider, the at least an upper bead hole is set corresponding to at least a lower bead hole set on the holder, the upper bead hole and the lower bead hole may be glided and corresponding to each other by shifting the slider, to control at least a lock ball gliding in and out, hereby perform unlocking and locking spacing on an inserting slice set on one end of the traversing part, to thereby achieve the burglarproof and prized-proof effect.

Abstract: The present invention relates to a bicycle lock structure with dual latch, which includes a latch seat and a lock body, wherein two parallel latches are set on one side of the latch seat, two inserting holes are set on one side of the lock body for inserting the latches, and at least a bead is drove to wedge into a wedged hole of the latch by a slider inside the lock body to form wedged locking, the lock picking difficulty is increased by such structure, to thereby improve the anti-theft effect.

Abstract: A bicycle lock set includes a main part and a connection member wherein an operation unit is located between the main part and the connection member. A shackle is movably connected to a first end of the main part and has two notches. A frame is linearly movable in the main part and has a first contact portion. A number wheel is rotatably connected to the frame and has a second contact portion which is engaged with the first contact portion. The operation unit includes an operation member which is driven and rotated by the frame and has a stud for being engaged with one of the notches when the shackle is moved toward the main part. A receiving space is defined in the operation member and a bead is partially received in the receiving space or pushed to protrude out from the main part.

Abstract: A light assembly includes a light unit having a case and a base, and a light source is connected to the light unit. A support unit includes a reception portion and a bendable portion which extends from the reception portion. The base is connected to the support unit and the bendable portion is mounted to a part of the base. The bendable portion can be bent downward to form a support portion which is put on the desk or a floor. A hooking member is connected to an outside of the reception portion such that the light assembly can be hooked to an object.

Abstract: A bicycle tool assembly includes a base having two base plates and a bar is connected between the two base plates. A tool set is pivotably connected to the bar. A chain tool assembly includes a first chain tool set and a second chain tool set, wherein the first chain tool set is pivotably connected to the bar and includes a clamp portion to clamp a chain. The second chain tool set is a board having a bent portion so as to be mounted to the tool set. The second chain tool can be removed from the base and is engaged with the first tool chain set. A push member is movably connected to the first chain tool set so as to reach the clamp portion to access the pins of the chain.
