The core of customizing "helier-grade" bicycle parts lies in integrating the aviation industry's pursuit of ultimate performance, lightweight and complex structures into the design and manufacturing of bicycles. The entire process revolves around this core contradiction and is a highly integrated project from design to manufacturing.
In-depth analysis of Core processes
The realization of "helicopter bicycle" parts mainly involves the following two technical routes:
Route One: Aviation Derivative Route (Performance First
The inspiration for this route directly comes from aviation manufacturing, such as the famous "Airbike", which is made of a mixture of nylon, carbon fiber and metal powder and formed in one piece through layering manufacturing (3D printing).
Core process: 3D design → Additive manufacturing (such as laser sintering) → possible post-curing/sintering → Precision machining (such as CNC partial finishing) → assembly.
Advantages: It offers an extremely high degree of design freedom, enabling the creation of topological optimization structures that are unachievable through traditional methods (such as bionic skeletons), and achieving the best stiffness/weight ratio. The product is integrally formed, with a very small number of parts and an extremely strong structural integrity.
Challenges: The manufacturing cost is extremely high, the production speed is slow, and it is more suitable for prototypes, small-batch customization or top-limited edition products. The anisotropy of the material is significant, and the requirements for process control are strict.
Route Two: Advanced Injection Molding Route (Balancing Efficiency and Performance)
This is currently the mainstream direction for high-performance bicycle components (such as frames and handlebars) to enter mass production. It makes a leap forward on the basis of traditional plastic molding by integrating multiple cutting-edge injection molding technologies.
Core process: Taking the handlebar as an example, its core is the "one-step" manufacturing method: Continuous carbon fiber reinforced Tape (UD Tape) is pre-placed in the mold at the key force-bearing parts → Engineering plastics containing glass fibers (such as nylon 6) are injected → at the same time, gas is injected using the "fluid core melting technology" to form a hollow complex inner cavity and push the molten plastic back to the machine for recovery → the mold is cooled and opened to obtain the finished product.
Advantage: An outstanding balance between efficiency and performance. The production cycle can be as short as about 60 seconds, making it suitable for larger quantities. Through local reinforcement and hollow thin-walled design, it achieves excellent rigidity and fatigue resistance while reducing weight (about 15% lighter than aluminum). The design freedom is also much higher than that of traditional metal processing.
Challenge: The initial investment in molds and specialized equipment (such as rodless injection molding machines) is huge. The process development is complex and requires a high degree of coordination among materials, molds and automation.
⚙️ How to choose technology
Key suggestions and action steps
Clarify requirements and budget: This is the first step in decision-making. You need to clarify whether the parts are for verifying concepts, participating in competitions, or preparing for commercial sales? What are the target annual output and unit cost budget?
Seeking cross-industry partners: No matter which route is chosen, it is necessary to look for suppliers with backgrounds in aerospace, automotive or top sports equipment manufacturing. They understand the culture of "performance first" and the corresponding quality control system.
Conduct early technical consultation: With a preliminary 3D design model, conduct a technical feasibility review with potential suppliers. They can offer valuable advice on material selection, process details, cost estimation and design optimization (DFM).
Emphasize testing and certification: Helier-grade parts mean ultimate reliability. The budget must include strict testing procedures, such as CT scans (to inspect the internal structure), fatigue tests (simulating tens of thousands of riding loads), and destructive tests, to ensure compliance with or exceeding relevant ISO standards.
If you could share more specific ideas about this part (for example, is it the frame, crank or other components?) What are the target weight and stiffness? What is the expected production scale?" I can offer you a more targeted analysis.
