Bicycle frames are constructed from a variety of materials depending on the quality and intended use of the vehicle.

Common materials include:

Low-carbon steel: Frequently used for standard bicycle frame tubing.1
Aluminum and chromium-molybdenum alloy steel: Utilized for better-quality frames.1
Advanced materials: High-end or more expensive frames are often manufactured using titanium or carbon-fiber composites.1

While design styles such as the traditional diamond frame or full-suspension mountain bike configurations vary, these materials remain the primary choices for structural integrity and performance.1
