From the early 21st century to the present, significant developments have been made in the materials, design, and manufacturing processes of electric bicycle frames. Here is a detailed introduction:
- Materials
- Aluminum alloy has been further popularized. Through the optimization of production processes and the addition of new alloying elements, its strength has been continuously enhanced while maintaining its lightweight characteristics. High – strength aluminum alloys such as 6061 and 7075 are widely used, and the surface treatment process has become more mature, improving corrosion resistance and aesthetics.
- With the gradual reduction in cost, carbon fiber materials have been increasingly used in high – end electric bicycle frames. Their high strength, high rigidity, lightweight, and good shock – absorption performance can bring a better riding experience to cyclists.
- New materials such as magnesium alloy have also begun to be used. Magnesium alloy has the advantages of being lightweight and having good shock – absorption, but due to the difficulty of manufacturing processes and cost issues, it has not been widely popularized yet.
- With the widespread application of lithium – ion batteries, the frame needs to adapt to the installation and fixation of lithium – ion batteries. There have been some frame structures and materials specifically designed for lithium – ion batteries to improve the safety and stability of the batteries.
- Design
- Greater emphasis has been placed on ergonomic design. According to the body sizes and riding habits of different people, the geometric structure of the frame has been optimized. For example, the distances and angles among the handlebars, seats, and pedals have been adjusted to make the riding position more comfortable and reduce fatigue.
- To meet consumers’ demands for personalization and functionality, the design of frames has become more diverse. Special designs such as folding frames and adjustable frames have emerged, which are convenient for carrying and storing or can adapt to different riding scenarios.
- Considering the endurance and power requirements of electric bicycles, the design of the frame has also paid more attention to the integration of the battery and the motor, making the overall layout of the vehicle more reasonable and the appearance more concise and smooth.
- Manufacturing Processes
- Welding technologies have been continuously innovated. Advanced technologies such as laser welding and robotic welding have gradually become popular, improving the welding quality and production efficiency, reducing the errors and defects of manual welding, and making the frame stronger and more stable.
- 3D printing technology has been applied to the prototype production of frame manufacturing and the production of some small – batch and customized products. It can quickly manufacture complex frame structures, shorten the product development cycle, and reduce costs.
- Composite material forming technologies have been continuously developed, such as resin transfer molding (RTM) and vacuum – assisted resin transfer molding (VARTM), which have improved the production efficiency and quality of carbon fiber and other composite material frames and reduced the production cost.
The corresponding table is as follows:
| Time | Materials | Design | Manufacturing Processes |
|---|---|---|---|
| From the early 21st century to the present | Optimization of aluminum alloy; popularization of carbon fiber; application of new materials such as magnesium alloy; emergence of frame materials suitable for lithium – ion batteries | Emphasis on ergonomics; diversification of personalized and functional designs; integrated design of battery and motor | Popularization of laser welding and robotic welding; 3D printing used for prototype production and customized production; development of composite material forming technologies |

Front and rear disc brakes ensure safe, responsive stopping, whether on mountain trails or city streets. – In the early days, steel was used in the manufacturing of bicycle frames. After the emergence of electric bicycles, steel frames were widely adopted due to their many advantages. Before the 1990s, chromium – molybdenum steel – made frames were the mainstream in bicycle frames, and most electric bicycle frames also used chromium – molybdenum steel. Chromium – molybdenum steel is an alloy steel made by adding two elements, molybdenum (Mo) and chromium (Cr), to carbon steel. It has good torsion and tensile properties, and high temperatures during welding do not affect the material. Moreover, it is inexpensive. At that time, the main […]
