摘要： A method for manufacturing a bicycle crank is revealed. After being extended, bent and forged, an aluminum alloy pipe becomes an L-shaped part formed by a cylindrical crankshaft portion and an oval crank portion integrally connected to each other. A plug is inserted into an outer end of the crank portion while a periphery of an outer end of the crankshaft portion is punched to form a shaft-connecting portion. An assembling hole is arranged at the outer end of the crank portion, corresponding to the plug. Thus a bicycle crank is produced. Thereby not only the assembly of the bicycle crank is easier and more convenient, the structural strength of the bicycle crank is increased effectively to against vibrations and impacts. The bicycle is lightweight and the bicycle crank is more streamlined so that consumers are attracted. Thereby the market competitiveness is increased.

摘要： A method for manufacturing a single chainring (1) which prevents a chain (3) from easily falling off and is low-cost is provided. The method for manufacturing a single chainring (1) comprises a step of forming neutral teeth (A) having a thickness allowing the neutral teeth (A) to be smoothly insertable into an inner link gap of a chain (3) and further comprises one or both of a step of forming outward teeth (B) by bending a part of the neutral teeth (A) outwardly in such a manner that the outward teeth (B) are insertable into an outer link gap of the chain (3) and a step of forming inward teeth (C) by bending a part of the neutral teeth (A) inwardly in such a manner that the inward teeth (C) are insertable into the outer link gap of the chain (3).

摘要： A motorcycle frame rack enables a motorcycle frame to be repaired without removing many components from the motorcycle. A motorcycle is positioned on the motorcycle frame rack, secured in place and then the frame is adjusted using chains coupled to towers. A self-centering laser measuring system is able to be used to analyze and measure damage to the motorcycle frame.

摘要： A cassette for a bicycle may include a plurality of sprocket portions joined together into a single unit. The cassette may include a cavity formed in the large end of the cassette. A related manufacturing method may include joining a first generally planar sprocket portion having a plurality of connector portions extending transverse to the plane of the first sprocket portion, to a second generally planar sprocket portion, e.g., by fusing at least one of the connector portions to the second sprocket portion.

摘要： A bicycle is provided having a unitary steering tube-crown member and a unitary crank arm-spindle member. A multistage aluminum 3D forging process is used to form the unitary members. This may allow the fabrication of components with substantially hollow interior areas to reduce weight, reduce part count while maintaining high strength and ductility. The multistage 3D forging process provided also allows the combination of multiple components into a single unitary part.
