Abstract: A bicycle frame apparatus is disclosed that includes a main frame, a sub-frame and a shock absorber. The sub-frame moves relative to the main frame. The shock absorber is positioned between the main frame and sub-frame so that the shock absorber effects movement of the sub-frame relative to the main frame. The main frame includes a down tube. The down tube includes an aperture. The shock absorber extends into and/or through the aperture to a connection point that, in some embodiments, is below the down tube.

Abstract: A method for making a bicycle frame part includes the steps of preparing a malleable tubular blank that has an outer surface and that is made from an alloy selected from the group consisting of Al—Mg—Sc alloy, Al—Mg—Zr alloy, and Al—Mg—Li—Zr alloy; placing the tubular blank in a mold such that the tubular blank is surrounded by an inner surface of the mold; heating the tubular blank to a working temperature ranging from 200 to 500° C; and injecting a high-pressure fluid into the tubular blank so as to permit expansion and permanent deformation of the tubular blank in the mold to an extent that the outer surface of the expanded tube abuts against and conforms to the inner surface of the mold.

Abstract: A spoke fastener includes a shank extending along a shank axis and having an anchoring portion and an operating portion. The anchoring portion is formed with resilient arm segments that are angularly spaced apart from each other relative to the shank axis. Each of the resilient arm segments has a distal end formed with a radial outward anchor projection to form the anchoring portion with an initial cross-section. The anchor projections are forcible radially and inwardly toward the shank axis to form the anchoring portion with a restricted cross-section, there by permitting extension of the anchoring portion through a spoke fastening hole in a wheel rim and retention of the anchoring portion on the wheel rim. A through hole extends through the operating and anchoring portions, permits extension of a spoke into the shank, and has a threaded segment for threaded engagement with the spoke.

Abstract: A suspension system may include a front frame connected to a front wheel, a shock absorber pivotally connected to the front frame, and a rear frame connected to a rear wheel supported by a ground contact point. The shock absorber may include a preset pressure substantially equal to a pressure caused by a body weight of a rider. The suspension system may be structurally configured to maintain an instantaneous center point of movement of the rear frame relative to the front frame within an angle range of about 45°±15° relative to the ground contact point when the rear frame moves relative to the front frame.

Abstract: A bicycle rear suspension system has a virtual pivot point that is close to a junction between a chain and a front driving sprocket when a piston rod travels relative to a cylinder body by ¼ to ⅓ of a maximum displacement value, and that moves rearwardly when a rear wheel moves upwardly away from the ground. A line interconnecting an instant center of a rear triangular frame and a contacting point between a rear wheel and the ground forms an angle of about 45° with respect to a horizontal line.

Abstract: A bicycle frame part made via a process that includes the steps of placing a one-piece metallic tube blank in a die; hydraulically forming the tube blank by introducing a hydraulic pressure into the tube blank to deform and expand the tube blank so as to form at least one expanded wall part projecting from the tube blank along a direction different from the direction of extension of the tube blank; and machining the expanded wall part to form a connection tube. A bicycle frame includes a plurality of frame parts connected to each other. At least one of the frame parts is formed via the aforementioned process, and includes a tube body and at least one connection tube projecting from the tube body in a direction different from the direction of extension of the tube body.
