Flextail – Mountain Bicycle with Integrated Flexible Rear Stay System
EU PATENT PENDING
CN PATENT PENDING
​​
This patent application relates to a mountain bicycle incorporating a flexible rear stay system, designed to improve comfort, traction, and control during off-road riding. The bicycle features an integrated flexible element within the rear stay structure that allows controlled vertical deflection in response to terrain variations.
​
Detailed Description
​
The mountain bicycle described in this patent application comprises a frame structure configured to support a front fork and a rear stay system. The rear stay system includes both a lower stay and an upper stay, at least one of which incorporates a flexible element.
The flexible element is configured to allow vertical deflection of the rear stay system when the bicycle encounters uneven terrain, impacts, or surface irregularities. This controlled deflection improves shock absorption and enhances rear wheel traction without the use of traditional mechanical suspension components.
The flexible element comprises a carbon-based leaf spring mechanism, integrally formed within the rear stay structure. The carbon material and geometry of the leaf spring are designed to provide a predetermined and controlled flex pattern, allowing the rear of the bicycle to absorb impacts while maintaining lateral stiffness and pedaling efficiency.
The flexible rear stay system operates passively and does not require pivots, bearings, or additional damping components. This results in a lightweight, low-maintenance solution suitable for mountain bikes intended for competitive and performance-oriented riding.
​
Claims
-
A mountain bicycle comprising a frame structure configured to support a front fork and a rear stay system, wherein the rear stay system includes a flexible element configured to vertically deflect in response to terrain variations.
-
The mountain bicycle of claim 1, wherein the flexible element is integrated into at least one of a lower stay or an upper stay of the rear stay system.
-
The mountain bicycle of claim 1, wherein the flexible element comprises a carbon-based leaf spring mechanism configured to provide controlled flexion.

​
Concluding Statement
​
The Flextail mountain bicycle described in this patent application provides a simplified and lightweight solution for improving comfort, traction, and control by integrating a carbon-based flexible element directly into the rear stay system. The design offers the benefits of vertical compliance without the complexity of traditional rear suspension systems.
Carbon Rim for Mountain Bikes with Keel-Type Design
EU PATENT PENDING
This patent application relates to a novel design for a carbon rim used in mountain bikes. The rim features a unique keel-type shape that allows for thinner sides and increased thickness in the inner rim where the spokes are attached. This design enhances the strength, durability, and overall performance of the mountain bike rim.
Detailed Description
​
The carbon rim for mountain bikes described in this patent application includes a keel-type design that provides several advantages over traditional rim designs. The keel shape of the rim allows for thinner sidewalls while maintaining structural integrity and stiffness. Additionally, the inner rim area where the spokes are attached is reinforced with increased thickness to support the stress and load distribution during riding.
The carbon rim is manufactured using high-quality carbon fiber materials and advanced molding techniques to ensure precision and consistency in the keel design. The dimensions and angles of the keel shape are optimized for optimal strength-to-weight ratio, providing a lightweight yet robust rim solution for mountain bike enthusiasts.
In conclusion, the carbon rim with a keel-type design presented in this patent application offers a significant improvement over existing rim designs in terms of performance, durability, and weight savings. The innovative construction of the rim addresses the specific needs of mountain bikers seeking a reliable and high-performance component for their bikes.
Claims
1. A carbon rim for mountain bikes comprising a keel-type design that allows for thinner sidewalls and increased thickness in the inner rim area where the spokes are attached.
2. The carbon rim of claim 1, wherein the keel shape enhances the structural integrity and stiffness of the rim while reducing weight.
3. The carbon rim of claim 1, further comprising reinforced carbon fiber materials in the inner rim area to support stress and load distribution during riding.
4. The carbon rim of claim 1, manufactured using advanced molding techniques to ensure precision and consistency in the keel design.
​
Concluding Statement
​
The carbon rim with a keel-type design described in this patent application provides an improved structural configuration for mountain bike rims by redistributing material toward the inner rim area where the spokes are attached. This allows the sidewalls to remain thinner while maintaining high strength and stiffness. As a result, the rim achieves enhanced durability, improved load distribution, and a favorable strength-to-weight ratio. The design is particularly suitable for mountain bike applications requiring reliable performance under demanding riding conditions.

Carbon Rim for Mountain Bikes with Multi-Curved Surface Design
EU PATENT PENDING
​
This patent application relates to a carbon rim for mountain bikes, specifically designed for competitive use. The rim features a novel surface geometry in which the rim surface is no longer formed as a single arc-shaped curve, but instead is composed of several interconnected curved surfaces. This design significantly increases the lateral rigidity of the rim, improving acceleration efficiency and riding performance.
​
Detailed Description
​
The carbon rim for mountain bikes described in this patent application is characterized by a cross-sectional shape in which one or more surfaces of the rim are formed by multiple curved surface segments joined together. Unlike conventional rims that use a continuous arc-shaped surface, the present design divides the surface into several curved sections with different curvature profiles.
This multi-curved surface configuration increases the lateral rigidity of the rim by approximately 50–55% compared to traditional carbon rims of similar weight. The increased rigidity reduces lateral deformation during riding, resulting in more efficient energy transfer, faster acceleration, and improved handling.
The rim is manufactured from carbon fiber composite materials using precision molding techniques to accurately form the multiple curved surfaces. The geometry of the curved surfaces is designed to enhance stiffness without a significant increase in material volume or weight.
The rim is particularly intended for competitive mountain bike applications, where high rigidity and rapid acceleration are critical performance factors. By increasing lateral stiffness rather than simply increasing material thickness, the design improves product competitiveness while maintaining a lightweight structure.
​
Claims
​
-
A carbon rim for mountain bikes, wherein a surface of the rim is formed by a plurality of interconnected curved surfaces instead of a single arc-shaped surface.
-
The carbon rim of claim 1, wherein the plurality of curved surfaces increases the lateral rigidity of the rim by approximately 50–55% compared to a conventional arc-shaped rim of similar weight.
-
The carbon rim of claim 1, wherein the interconnected curved surfaces reduce lateral deformation and improve energy transfer during riding.
-
The carbon rim of claim 1, wherein the rim is designed for competitive mountain bike use requiring increased rigidity and faster acceleration.
-
The carbon rim of claim 1, wherein the rim is manufactured from carbon fiber composite materials using molding techniques configured to form the plurality of curved surfaces.
​
Concluding Statement
​
The carbon rim with a multi-curved surface design described in this patent application provides a significant improvement over existing mountain bike rim designs by substantially increasing lateral rigidity without increasing weight. The design is especially suited for competitive riders seeking enhanced acceleration and performance.
