Abstract: A rim and a method for manufacturing a rim in particular for bicycles in which first a rim body is manufactured having a hollow space with a radially outer and a radially inner hollow-space wall. The radially outer hollow-space wall has a diameter matched to the diameter of a tube tire and the radially inner hollow-space wall has a diameter matched to the diameter of a wire tire.

Abstract: A bicycle rim and a method for manufacturing a bicycle rim which bicycle rim includes a rim body which includes at least a rim base and brake sidewalls. The rim body consists at least in part of a fibrous composite material and the brake sidewalls include a brake layer of a friction-enhancing material.

Abstract: A rim and a method for manufacturing a rim, in particular for a bicycle, includes a rim body and multiple spoke holes in the rim body for receiving at least part of a spoke and/or spoke nipple. The rim body consists of a fiber-reinforced material including a thermoplastic matrix material. Separate rim eyelets are provided located at the spoke holes and connected with the rim body.

Abstract: The invention relates to a rim and to a method for its production, in particular for bicycles, using a machining device for the working a welding burr of the rim. The machining device comprises a machining means working the outer contour of the rim and a another machining means working the inner contour of the rim, that has an outer diameter being less than the width of the rim well. The main steps of the method include movement of the first means along the outer contour of the rim to work the welding burr on the outer contour and movement of the second means along the inner contour of the rim to work the welding burr on the inner contour. During machining the inner contour the rim is pivoted around an axis by a predefined angular range.

Abstract: The present invention relates to a device and to a method for coating bicycle components. According to the invention, the device has at least one power supply unit, at least one liquid tank and at least one conveying means for the bicycle components to be coated. On the power supply unit, there are at least two electrodes that are connected to the bicycle components and arranged in the liquid tank. In the liquid tank, there is also a carrier solution having a prescribed proportion of a coating substance, where the electric circuit to the power supply unit is closed when at least one component is at least partially brought into contact with the liquid. The coating substance is deposited at least as a function of a prescribed electric current.

Abstract: A wheel, a rim, a rim eyelet and a spoke nipple, particularly for a bicycle, wherein the rim eyelet has a throughbore to receive a spoke nipple. The spoke nipple includes a nipple body and a nipple thread to work in concert with a spoke. At least one contact layer made from a material which effects a reduction in friction at the area of contact is provided between the spoke and the rim eyelet of the wheel's rim.

Abstract: The invention relates to a device for transporting human beings, comprising a frame, at least one tire extending in a peripheral direction around a wheel with a certain amount of elasticity, and a braking system. The braking power of the braking system is substantially independent from the elasticity of the tires. The invention also relates to a method for arresting said transportation device.

Abstract: The invention relates to a hub for bicycles and the like, comprising a hub axle and a hub housing concentrically mounted in relation thereto including a bearing device having at least two bearings mounted between the axle and the housing. A rotor (25) for receiving at least one toothed wheel is disposed on the hub axle (4) and a free-wheel device is arranged between the rotor and the housing of the hub, said device having two toothed discs (22, 23), the toothed surfaces of which are pressed against each other by a pretensioning device. The toothed surfaces of which are pressed against each other by a pretensioning device. The toothed discs are mounted ina substantially concentric manner in relation to the hub axle (4) on planes which are aligned perpendicular to the hub axle. The toothed discs are float mounted or fixed so that the toothed discs can be tilted in relation to the hub axle.

Abstract: Freewheel hub, especially for bicycles and similar contrivances comprising a hub axle, a hub shell arranged concentrically thereto, a rotator arranged concentrically to said hub axle for receiving a sprocket wheel with pinions and a freewheel means disposed with ratchet pawls. Roller bearings are employed for the rotatable support of said hub shell relative the hub axle and for the rotatable support of said rotator relative said hub shell and comprise roller bodies each respectively disposed at a predetermined distance from one another.
