Overview

Geometry, lightness and a real prototype

Designed as a bachelor’s thesis in collaboration between the Ladislav Sutnar Faculty of Art and Design and the Faculty of Mechanical Engineering, this electric motorbike concept targets young urban riders. Blending mathematical precision with fluid lightness, it features a customizable battery box with a status indicator, integrated storage replacing the fuel tank, and an alcantara seat.

The project was taken from sketch to a full-scale clay prototype on a real motorcycle — covering concept design, surface exploration, and physical sculpting.

Design methodology

Two Core Explorations

Two design approaches were developed in parallel — one driven by geometric lines, the other by lightness — sharing an identical technical package.

01

FLOWING

The lightweight counterpart to the geometric layout. Focuses on fluid silhouette lines, a forward-extended ergonomic seat and a compact front fairing.

02

GEOMETRIC

Based on mathematically connected lines and faceted surfaces that converge precisely to a single vanishing point at the tail light.
