Bicycle Spinner Peg with Rotating Wheel and Stationary Fender
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional BMX pegs limit the creativity and execution of BMX tricks, as they do not allow for novel combinations and often fail to provide a spinning peg that can also serve as a stationary standing surface, making it difficult for riders to perform complex maneuvers.
Innovation Solution
A bicycle spinner peg device featuring a spinning wheel attached to a non-rotational fender, allowing riders to roll along surfaces while performing tricks and providing a stationary standing surface, enhancing the BMX riding experience by enabling previously impossible tricks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional peg is used for grinding on rails and walls, then the basic grinding function is achieved, but the ability to perform novel tricks and combinations is limited
Solution Approach 1:
The peg device combines multiple functions into a single component: the fender provides a stationary standing surface for grinding tricks, while the wheel assembly attached to the shaft provides a rolling surface for wheelie tricks and other maneuvers. This multi-functional design allows riders to perform both traditional grinding tricks and novel wheel-based tricks without needing separate pegs for each function.
Solution Approach 2:
The peg device incorporates a dynamic wheel assembly that can rotate around the shaft, transitioning from a static peg structure to a dynamic system. The wheel can spin freely when needed for tricks, while the fender remains stationary to provide stable foot placement. This dynamic capability enables tricks that require both rotational motion and stationary support.
2Adaptability or versatility
If a spinning wheel is added to the peg to enable rolling along surfaces, then novel tricks become possible, but the device complexity increases
Solution Approach 1:
The wheel assembly is nested within the peg structure, with the wheel rotating around the shaft that passes through the fender. The bearing allows the wheel to spin independently while remaining contained within the compact peg assembly. This nested design adds the rolling function without significantly increasing the overall size or complexity of the peg device.
3Stability of the object's composition
If a stationary standing surface is provided for foot placement, then stability for grinding tricks is improved, but the ability to roll along surfaces is reduced
Solution Approach 1:
The peg device is segmented into distinct functional components: the fender provides a stationary standing surface for stable foot placement during grinding tricks, while the wheel assembly on the shaft provides a separate rolling surface for maneuvers requiring motion. This segmentation allows each component to perform its specific function optimally without interfering with the other.

AI summary
A bicycle spinner peg device is provided. The device is comprised of a shaft with at least one wheel which spins around the shaft. The shaft also receives a fender, which rests above the wheel, that attaches to the shaft in a non-rotational manner. The device is also comprised of a peg thread that allows the device to attach to the peg receiving area of a bicycle. As a result, a user can use the wheel of the peg to roll along a surface while performing a BMX trick. While doing so, the user can also stand on the fender, which does not rotate as the wheel rolls along the surface.
