Goran Juric Design portfolio | 2022 | Carbon Bicycle — Lightweight Urban Mobility Concept | Independent Research
Challenge: Create an ultra-lightweight urban bicycle optimized for environments where portability is as important as performance. In dense urban housing, the daily act of carrying a bicycle up several flights of stairs transforms weight from a technical specification into a decisive factor of usability.
Solution: The concept explores structural efficiency through extensive use of carbon fiber composites, minimizing metallic components to only those essential for structural integrity, threading, and load-bearing. The result is a bicycle that redefines the relationship between material, form, and function — retaining full mechanical reliability while achieving significant weight reduction.
Frame and fork form a unified carbon monocoque structure optimized for stiffness-to-weight ratio. Wheels, seatpost, and handlebar assemblies are also executed in carbon, while drivetrain, hubs, and key connectors remain metallic for durability and precision.
The outcome demonstrates a reduction of approximately 25–40% compared to conventional metal-frame bicycles, achieving a total mass below 9 kg — light enough to carry with one hand, yet structurally rigid for everyday use. The carbon architecture not only reduces physical effort but also expresses a new aesthetic of efficiency — where lightness becomes a visible design language.
Philosophy: In this concept, material becomes the design narrative. Every component exists only for a defined purpose, every gram serves a function. The result is not decorative minimalism but engineered clarity — a mobility tool refined to its essential logic.
