Description

SYSTEMS AND DEVICES FOR BICYCLE WHEELSCROSS-REFERENCE

[0001] The present application claims priority under 35 U.S.C. § 119(e) to U.S. Application No. 63 / 664,533, filed on June 26, 2024 and entitled “SYSTEMS AND DEVICES FOR BICYCLE WHEELS,” which is hereby incorporated by reference in its entirety.FIELD

[0002] The present application generally relates to systems and devices for bicycle wheels, and more specifically, to a bicycle wheel that includes spokes anchored to the rim of the wheel on both ends, with the spokes passing through a hub of the bicycle wheel.BACKGROUND

[0003] Bicycle wheels include a variety of components in order to transmit power from the pedals to the road. Two of these components include the hub of a bicycle wheel and spokes, which connect the hub to a rim of a bicycle wheel. Spokes are rods that connect the hub to the rim. They transmit the power generated by pedaling and serve to keep rims round and true. Presently, the spokes extend from the hub in a straight line and secure to the inner circumference of a rim, and the hub itself. Spokes can include a nail head on a first end, and a thread on a second end. The nail head is positioned such that it does not allow an end of the spoke to pass through the hub, anchoring the spoke to the hub. The threaded end can then be attached to the rim, and tightened down to achieve a proper tension in the spoke. However, this can create stress concentrations on the hub via the nail head, which can lead to premature failure of a hub.Additionally, due to the enlarged size of the nail head compared to the spoke body, the nail heads need to be positioned such that they are offset on the hub, resulting in four separate planes which forces are being applied on the wheel. These multiple planes can make balancing the forces difficult and time consuming.

[0004] Some modern spoke designs attempt to address these issues by using a looped-end or knotted configuration, in which one end of the spoke is threaded and secured to the rim, while the opposite end forms a loop or knot that is retained within a slot or hook on the hub. While thisapproach eliminates the need for a nail head or J-bend, it introduces new challenges. The looped end or knot can be bulky and difficult to manufacture consistently, especially when using textile or composite materials. Additionally, the looped or knotted interface can introduce slippage or uneven load distribution under tension, particularly if the loop or knot is not perfectly aligned or if the hub interface lacks sufficient friction or retention features. These factors can lead to premature loosening, spoke elongation, or failure under dynamic loading conditions.SUMMARY

[0041] Certain exemplary aspects will now be described to provide an overall understanding of the principles of the structure, function, manufacture, and use of the devices and methodsdisclosed herein. One or more examples of these aspects are illustrated in the accompanying drawings. Those skilled in the art will understand that the devices and methods specifically described herein and illustrated in the accompanying drawings are non-limiting exemplary aspects and that the scope of the present invention is defined solely by the claims. The features illustrated or described in connection with one exemplary aspect may be combined with the features of other aspects. Such modifications and variations are intended to be included within the scope of the present invention.

[0042] Various systems and devices for bicycle wheels are provided herein. The present disclosure provides a “boomerang” spoke configuration, in which the spoke is threaded at both ends and passes through a channel in the hub. This design eliminates the need for a loop or head at the hub interface, reducing stress concentrations and simplifying the spoke’s geometry. The boomerang configuration allows for precise tensioning from both ends of the spoke and is compatible with both rigid and flexible spoke materials, including textile-based constructions.

[0043] FIG. 1 illustrates a wheel assembly 100. The wheel assembly 100 can include a rim 102, spokes 104, and a hub 106. The rim 102 includes an inner circumference 103. The hub 106 is positioned within the center of the rim 102, and is held in place by spokes 104. The spokes 104 secure to the rim 102 at the inner circumference 103, and secure to the hub 106 through protrusions 108a and protrusions 108b, which will be described in more detail further below. The wheel assembly 100 is illustrated as a bike wheel, but other forms of vehicles (i.e., automobiles, trailers, aircraft) can be used with the wheel assembly 100. In some aspects, the wheel assembly 100 may be adapted for use in ultralight or high-performance applications, such as racing bicycles, electric scooters, or unmanned aerial vehicles (UAVs), where weight, strength, and vibration damping are critical. The design of the wheel assembly allows for compatibility with both rigid metal spokes and flexible textile spokes, enabling a wide range of performance characteristics. The use of dual-ended spoke anchoring and hub-integrated channels provides a robust and modular architecture that can be tuned for different use cases, including off-road durability, aerodynamic efficiency, or ease of maintenance.

[0044] FIGS. 2-3 illustrate the hub 106 in isolation. As depicted, the hub 106 includes a center through-bore 106a, which is configured to receive a driveshaft (not shown). Additionally, thehub 106 includes a set of inner teeth 106b positioned within the through-bore 106a in order to transmit power from the cassette (not shown) to the hub 106. In an aspect, the through-bore 106a may be dimensioned to accommodate various axle diameters and may include integrated bearing seats or interfaces for cartridge bearings, bushings, or other rotational support elements. The inner teeth 106b may be configured to engage with a splined cassette body or other drive mechanism, enabling efficient torque transfer from the drivetrain to the wheel. In some embodiments, the hub 106 may also include integrated features such as torque limiters, ratcheting mechanisms, or electronic sensors for monitoring rotational speed or load. These enhancements can support advanced drivetrain systems, including electric-assist bicycles or smart wheel platforms.

[0045] A plurality of projections 107a is positioned on a first end of the hub 106, and a plurality of projections 107b positioned on a second end of the hub 106. The plurality of projections 107a includes projections 108a extending about the hub 106 in a radial configuration. The projections 108a can be trapezoidal in shape, but other types of shapes (i.e., rectangular, square) can be used and should be considered within the scope of this disclosure. Positioned within each of the projections 108a is a channel 110a that passes through the whole of the projection 108a. The channel 110a can be a through-bore with a circular opening that allows a spoke 104 to pass therethrough. As shown in FIG. 4, the channels 110a can include chamfered edges to correspond to the bent shape of a spoke 104 passing through the channels 110a. The use of radially arranged projections with integrated channels allows for a modular and scalable hub design. Each projection acts as an independent spoke interface, which simplifies manufacturing and enables customization of spoke count and pattern. The through-bore channels 110a may be precision- machined or molded to match the geometry of the spoke, including circular, elliptical, or flat cross-sections. In aspects utilizing textile spokes, the channels may include internal contours or surface treatments to enhance grip and prevent slippage under load. The chamfered or contoured edges reduce stress concentrations at the spoke interface, which is particularly important for high-tension applications or when using non-metallic spoke materials.

[0046] The plurality of projections 107b is axially displaced along the hub 106 from the plurality of projections 107a. The plurality of projections 107b includes projections 108b, which include a channel 110b in each projection 108b. Similar to the projections 108a, the projections 108b canbe trapezoidal in shape and configured to receive a spoke 104 through the channel 1 10b. As shown in FIG. 5, the channels 110b can include chamfered edges to correspond to the bent shape of a spoke 104 passing through the channels 110b. In an aspect, the diameter of the projections 110b can be smaller than the diameter of the projections 110a. The axial displacement between the projections 107a and 107b allows for a staggered spoke pattern that enhances load distribution and wheel stability. In an aspect, this configuration also enables the use of alternating spoke geometries or materials on opposite sides of the hub, such as combining rigid metal spokes on one side with flexible textile spokes on the other. The channels 110b may be optimized for different spoke types, including those with variable stiffness or cross-sectional profiles. In some embodiments, the channels may include integrated locking features, such as internal ridges or grooves, to further secure the spoke within the hub and prevent rotational or axial movement under dynamic loading conditions.

[0047] As depicted in FIG. 3, the projections 108a are aligned along a single plane 112. Additionally, the projections 108b are aligned along a single plane 114. Due to this configuration, the tension force which is applied by the spokes 104 on the hub 106 is aligned within only two planes 112, 114. Unlike traditional hubs, where there are four planes that apply tension forces to the hub due to the axially staggered arranged of the spokes and the hub on each projection. This alignment increases the strength of the hub 106, and also aids in balancing the forces between the rim 102 and the hub 106 via the spokes 104. By reducing the number of force planes from four to two, the system simplifies the mechanical load paths and minimizes asymmetric stress distributions that can lead to premature fatigue or failure. This planar alignment also facilitates more predictable spoke tensioning during assembly and maintenance, improving wheel trueness and long-term durability. In embodiments using textile or flexible spokes, this configuration is particularly advantageous, as it reduces the complexity of spoke routing and ensures that tension is applied in a consistent and controlled manner. The simplified geometry also allows for automated or semi-automated wheel building processes, which can improve manufacturing efficiency and consistency.

[0048] FIG. 6 depicts a spoke 104 in isolation. As shown, the spoke 104 includes a first end 104a, a second end 104b, and a middle portion 122 positioned between the first end 104a and the second end 104b. The first end 104a can include a threaded surface which engages with a nipple105a. The nipple 105a is positioned on the spoke 104 and includes a corresponding threaded surface (not shown). One end of the nipple 105a is placed within the hub 102, with a portion extending radial inward towards the hub 106. The spoke 104 can then be tightened to a specific load by using the threaded connection at the first end 104a and the nipple 105a. Similarly, a nipple 105b is positioned adjacent the second end 104b, and also includes a corresponding threaded surface to the threaded surface of the second end 104b. The nipple 105b would be positioned in the hub 102 similar to the nipple 105a. This dual-threaded configuration allows for tensioning from both ends of the spoke, which is particularly advantageous in the boomerang spoke design where the spoke passes through the hub and is anchored at both ends to the rim. This setup eliminates the need for traditional spoke heads or J-bends, which are common failure points due to stress concentrations. In aspects using textile spokes, the threaded ends may be formed by bonding or molding threaded inserts into the fiber bundle, or by weaving the fibers around a threaded core. This enables the use of high-tensile textile materials — such as carbon fiber, aramid, or titanium-based filaments — while maintaining compatibility with standard rim hardware. The nipples 105a and 105b may also be adapted to accommodate the unique properties of textile spokes, such as by including compression sleeves or anti-rotation features to prevent fraying or twisting during tensioning.

[0049] In some aspects, the spokes 104 may be formed from textile materials rather than rigid metal rods. These textile spokes may include high-tensile synthetic fibers such as nylon, aramid, carbon fiber, or titanium-based filaments woven into a flexible cord. These materials offer advantages in weight, compliance, and fatigue resistance. However, attaching textile spokes to the hub presents unique challenges. Traditional I-bend or nail-head configurations used in metal spokes are not suitable for flexible textile materials, as they rely on rigid mechanical retention in hub flanges.

[0050] To address this, some manufacturers have attempted to secure textile spokes using knots, oversized threaded ends, or molded anchors. These solutions can be bulky, difficult to tension, or prone to slippage. The present disclosure provides an alternative solution through the use of a boomerang spoke configuration. In this configuration, the spoke is threaded at both ends and passes through a channel in the hub protrusion. The bent middle portion of the spoke — whether rigid or flexible — is retained within the channel, eliminating the need for a fixed anchor point atthe hub. This design avoids stress concentrations and allows the spoke to be tensioned from both ends at the rim. The boomerang configuration is particularly advantageous for textile spokes, enabling a clean, low-profile interface with the hub and consistent tensioning.

[0051] A straight portion 120a extends from the first end 104a to the middle portion 122, and a straight portion 120b extends from the second end 104b to the middle portions 122. The middle portion 122 can include a bent section that is positioned within the channels 110a, 110b, as shown in FIGS. 8-9. As stated above, the channels 110a, 110b can have a cross-sectional shape which corresponds to the bend in the spokes 104. This correspondence, in combination with the lack of a nail head of a traditional spoke, reduces the stress concentrations on the projections 108a, 108b of the hub 106. This can decrease fatigue on the hub 106 due to reduced stress concentrations, which increases the useful life of the hub 106 itself. Due to the threaded ends 104a, 104b of the spokes 104, the ends 104a, 104b of the spokes 104 are secured to the rim 102 at different angular positions. In an aspect, the angular positions can be between a range of 120 degrees to 180 degrees. This angular offset between the two ends of the spoke allows for a more even distribution of radial and tangential forces across the rim, improving wheel balance and reducing the likelihood of localized deformation. In aspects using textile spokes, the bent middle portion may be formed by pre-shaping the fiber bundle or by routing it through a curved guide during installation. The flexibility of textile materials allows them to conform naturally to the channel geometry, which can be optimized to minimize friction and wear. Additionally, the absence of a rigid spoke head or J-bend eliminates a common failure point and simplifies the spoke’s path through the hub. This design also facilitates the use of continuous or looped spoke structures, where a single textile strand may serve as two opposing spokes, further reducing weight and part count.

[0052] In order to secure the spokes 104 to the rim 102 and hub 106, the spoke 104 can be fed through the channels 110a, 110b, and then secured to the rim at the threaded ends 104a, 104b. The spoke 104 can then be tightened using the nipples 105a, 105b to apply a specific tension load between the rim 102 and the hub 106. This method of installation allows for precise control over spoke tension, which is critical for maintaining wheel trueness, strength, and ride quality. The dual-threaded configuration enables tensioning from both ends of the spoke, which can be particularly useful in automated wheel -building processes or in field-serviceable designs. Inembodiments using textile spokes, the threading may be achieved through integrated molded ends or by attaching threaded ferrules to the fiber bundle. The ability to tension the spoke from both ends also allows for fine-tuning of spoke preload, which can be used to optimize wheel stiffness or compliance depending on the application. Additionally, because the spoke is anchored at both ends to the rim and only passes through the hub, the hub itself is subjected to lower peak stresses, improving its fatigue life and allowing for lighter hub designs.

[0053] FIGS. 10-14 illustrate another aspect of a hub 206 that can be used with the wheel assembly 100. The hub 206 is similar to the hub 106, and therefore, like components will not be discussed in detail. However, hub 206 introduces additional features that enhance compatibility with a broader range of spoke types, including textile and bladed spokes. These features are particularly useful in applications where weight savings, aerodynamic performance, or vibration damping are critical. The design of hub 206 allows for simplified spoke insertion and retention, especially in cases where traditional spoke heads or flanges are not feasible. In an aspect, the hub 206 introduces additional structural and functional enhancements that improve compatibility with a wider range of spoke types and simplify the spoke installation process. In particular, hub 206 is designed to accommodate both rigid and flexible spokes, including textile-based variants, by incorporating side-entry channels and integrated retention features. These modifications allow for easier spoke routing and reduce the need for complex spoke heads or anchoring mechanisms. The design also supports high-tension applications while minimizing stress concentrations at the hub interface, thereby extending the service life of the wheel assembly. Furthermore, hub 206 may be manufactured using advanced techniques such as additive manufacturing or precision casting to achieve complex geometries and material efficiencies not possible with traditional machining.

[0054] The hub 206 includes a through-bore 206a configured to house an axel, and inner teeth 206b for transmitting power from the cassette to the hub 206. The hub 206 includes a plurality of projections 207a and a plurality of projections 207b. The projections 208a forming the plurality of projections 207a are similar to the projections 108a, but further include a channel 210a that is positioned through a sidewall of the projections 208a. Additionally, the projections 208a include a lip 21 la that extend radially inward towards the hub. Due to the position of the channel 210a, the lip 21 la aids in securing the spoke 104 within the channel 210a. This side-entryconfiguration allows for simplified spoke installation, particularly in cases where the spoke is flexible or textile-based and cannot be inserted axially. The lip 21 la functions as a mechanical stop that prevents the spoke from backing out of the channel under tension. This is especially beneficial for textile spokes, which may not have rigid heads or flanges to retain them in place. The geometry of the channel 210a can be tailored to match the cross-sectional profile of the spoke, whether circular, elliptical, or flat-bladed, ensuring a snug and secure fit.

[0055] The projections 208b forming the plurality of projections 207b are similar to the projections 108b, but further include a channel 210b that is positioned through a sidewall of the projections 208b. Additionally, channel 210b can include a downward radial slant towards the hub 206 to secure the spokes 104 within the channel 210b. This slanted configuration facilitates the insertion of flexible or textile spokes by allowing them to be guided naturally into position under tension. The downward angle also helps maintain spoke alignment during wheel rotation and load cycles, reducing the risk of spoke migration or loosening. In embodiments using textile spokes, the channel 210b may include a textured or contoured interior surface to increase friction and prevent slippage. The geometry of the channel may also be optimized to accommodate a range of spoke diameters and shapes, including flat, braided, or multi-strand textile constructions. This adaptability makes the hub 206 particularly well-suited for modem wheel designs that prioritize weight savings and modularity.

[0056] As shown in FIG. 11, similar to the hub 106, the projections 208a are aligned in a single plane 212, and the projections 208b are aligned in a single plane 214. Additionally, as shown in FIGS. 12-13, the projections 208a, 208b can be trapezoidal in shape. The channels 210a, 210b can be curved as they pass through the projections 208a, 208b. The curve of the channels 210a, 210b can correspond to the bend of the spokes 114 arranged in the channels 210a, 210b, as shown in FIG. 14. Additionally, thin, bladed spokes can be used with the hub 206, where a thin portion of the spoke rests in the channels 210a, 210b, where traditional circular spokes could not be inserted. The curvature of these channels is designed to correspond to the natural bend or deflection of the spoke, particularly in the case of flexible or textile spokes that may not maintain a rigid linear profile. This curvature helps distribute mechanical loads more evenly along the spoke’s length and minimizes localized stress concentrations at the hub interface. In someembodiments, the curvature may be asymmetric or helically profiled to accommodate specific spoke geometries or to optimize aerodynamic performance.

[0057] As shown in FIG. 14, the curve of the channels 210a, 210b can correspond to the bend of the spokes 114 arranged in the channels 210a, 210b. Additionally, thin, bladed spokes can be used with the hub 206, where a thin portion of the spoke rests in the channels 210a, 210b, where traditional circular spokes could not be inserted. This compatibility with non-cylindrical spoke profiles allows for the use of aerodynamic or lightweight spoke designs, including those made from composite or textile materials. The ability to accommodate a wide range of spoke types makes the hub 206 highly versatile and suitable for performance-oriented applications such as racing bicycles, ultralight mobility devices, and advanced recreational equipment.

[0058] In the descriptions above and in the claims, phrases such as “at least one of’ or “one or more of’ may occur followed by a conjunctive list of elements or features. The term “and / or” may also occur in a list of two or more elements or features.
