A junction system for bicycle frames.
Bicycle manufacturing presents several challenges. Firstly, the molding techniques used to create specific parts make tooling very expensive. Additionally, replacing parts can be complex due to their lack of standardization. To overcome these obstacles, we had the idea of creating standardized parts for bicycle frames. However, achieving aesthetically pleasing junctions with standardized parts is difficult. This is where metal 3D printing additive manufacturing technology comes in. This technology allows us to design parts with precise and elegant junctions while maintaining standardization.
By integrating this patented system, we have succeeded in assembling bicycles without resorting to traditional molding or tooling. The system we have developed works like “plug and play,” where each piece fits perfectly into another, thus simplifying the assembly process. One of the major advantages of this product is the absence of welding and tooling, which greatly facilitates the replacement of parts. For instance, a bicycle initially designed for a child can be transformed into an adult bicycle by retaining some parts and replacing others.
The aluminum frame of the bicycle integrates multiple functionalities while maintaining a minimalist and streamlined aesthetic. We have used generative tools to create organic shapes in the junctions, drawing inspiration from biomimicry to optimize the design. With advanced technical optimization for the printing of the junctions, this allows for minimizing welding costs. Our goal is to seamlessly integrate additive manufacturing into the assembly process, revolutionizing bicycle production.The battery, intentionally exposed and not integrated into the frame, gives the electric bicycle a bold and distinctive look.
