A bicycle repair tool includes a base, a first tool assembly, a second tool assembly, and a third tool assembly. The base includes a connecting portion, a first plate portion, a second plate portion, and a protruded portion. The connecting portion includes a receiving space. The protruded portion is connected to the first plate portion and is received in the receiving space. The first tool assembly is pivotally connected to a first side of the base and is located between the first and second plate portions. The second tool assembly is pivotally connected to a second side of the base and is located between the first and second plate portions. The connecting portion is located between the first and second tool assemblies. The third tool assembly is receivable in the receiving space and includes a tool including a receiving hole removably connected to the protruded portion.

A tool assembly includes a first tool and a second tool. The first tool includes a first tool body, a ratchet mechanism defining a first hole, and a receiving space. The ratchet mechanism includes a ratchet having a plurality of teeth and a pair of pawls, and a first end of each of the pawls is received between two adjacent teeth. The second tool includes a first inner hexagonal wrench and a first outer hexagonal opener. The first outer hexagonal opener may be received in the first hole. When the first tool rotates relative to the ratchet mechanism along a first direction, the pawls rotates with the first tool and drives the ratchet together with the second tool rotates along the first direction; when the first tool rotates along a second direction opposite to the first direction, the ratchet together with the second tool is in a static state.

A chain tool has two members each having a first edge formed with an opening to be engaged with the opening of the other member so that the two members can be pivoted with respect to each other. Each member has an opposite second edge provided with a recess and also has a guide groove in communication with the recess and the corresponding opening, wherein the recess is lightly deeper than the guide groove. Each member further has a rib extending along the corresponding first edge and projecting into the corresponding opening to form a protruding portion. When the openings of the two members are brought into engagement, the protruding portion of each member is moved along the guide groove of the other member into engagement in the recess of the other member.

A multi-purpose tool system installed on the handle bars of a conventional bicycle. The tool system is formed of a main body, and an expansion mechanism, a plug and a fastener. The expansion mechanism is inserted in an open end of a handle bar of a bicycle and the fastener is tightened. This causes the expansion mechanism to expand and tighten against the interior surface of the handle bars thereby holding it in place. The expansion mechanism is formed of a plurality of wedges that are held together by binders. The main body holds a plurality of bits and a cover that includes a driver is connected to the main body by a locking mechanism. When a tool is needed, the cover is removed from the main body, a bit is removed from the main body and inserted into the driver and the cover is used as a handle.

A ratchet wrench tool set includes a box, tool bits receivable in the box, two side boards mounted to two sides of the box, and a ratcheting device. The ratcheting device includes a rotary connection plate to which a ratcheting head is mounted. The rotary connection plate is rotatably mounted to the two side boards and rotatable between an operation position and a storage position and includes a constraint step section. The slidable constraint cover has a front end that forms a constraint projection section and is slidably mounted between the two side boards. When the slidable constraint cover is moved frontwards, the constraint projection section engages the constraint step section to retain the ratcheting device in the operation position and when the slidable constraint cover is moved rearward, the constraint projection section disengages from the constraint step section to allow the ratcheting device to rotate to the storage position.

A tool for driving a chain pin out of a chain link includes a handle body which extends along a longitudinal axis and has a positioning element at a first end along the longitudinal axis, and a press-out device with an upper and a lower projection, which in each case delimit an intermediate element connecting the two projections, wherein through holes coaxial with one another are provided in the two projections and a driving screw with a press plunger is screwed into the upper projection at its end oriented towards the lower projection. This tool is intended to have good manual applicability, even for chains of different types, while at the same time having very small dimensions and being easy to transport, and in particular to enable machining of very narrowly constructed chain types. This is achieved by the fact that the handle body has, at the first end along the longitudinal axis, a guide device extending the handle body, in which guide device the press-out device is mounted so as to be movable along the longitudinal axis of the handle body between a first position in which the positioning element and the intermediate element of the press-out device form a chain space for positioning the chain link, and a second position in which the press-out device is spaced from the positioning element.

A multiple tool, including at least one tool body provided with a central portion and radial portions departing from said central portion, each of said radial portions carrying a respective tool. The multiple tool further includes at least a frame provided with at least an opening for removably housing said at least one tool body, and with peripheral seats for removably housing respective implements.

A method for mounting a flexible tube associated with braking hydraulics on a bicycle between a braking control member and a braking member. The method provides a mounting cable for use in locating the flexible tube within a bicycle frame element while the ends of the flexible tube are exposed so a respective end can be connected to the control member and the braking member. The method simplifies the insertion process and reduces damage to the flexible tube. A tool for inserting the flexible tube is also provided.

A skateboard tool having a fastener-engaging piece and a nut-engaging piece which work cooperatively to unscrew multiple fasteners simultaneously. The fastener-engaging piece has a handle and a body. The handle is rigidly connected to a shaft which extends into the body and is rotatably connected with a set of interconnected gears. The handle and shaft are rotatable with respect to the body. The body also includes a plurality of fastener-engaging bits that are rotatably driven by the gears. The handle and shaft are rotated, which in turn rotates the gears and rotates the fastener-engaging bits. There is also provided a wrench for engaging, and rotatably locking, nuts secured to the fasteners that are rotated by the fastener-engaging bits. The wrench has an elongated U-shaped body having a pair of legs and a connector base piece. Each of the legs includes at least one nut-receiving socket.

A bicycle alignment device can be used to align the nose of the bicycle seat with the top tube of the bicycle frame. In addition, the same device can be used to align the handlebar stem with the front tire of the bicycle. The device can use a pointing device, such as a pin or a laser pointer, to align the seat to the top tube. The device can be easily broken down into its components for easy and convenient storage when not in use.
