Bicycles are efficient, eco-friendly vehicles designed for personal transportation, recreation, and sport. Modern bicycles range from lightweight road bikes for speed, to rugged mountain bikes for off-road use, and hybrid models for everyday commuting. Advanced materials like aluminum alloys, carbon fiber, and steel are commonly used to ensure durability and performance.
Key features often include:
-
Gear shifting systems (single-speed or multi-speed);
-
Front and/or rear suspension;
-
Disc or caliper braking systems;

Ergonomic frames for comfort and posture support.
