The story

Geometric — the project.

Geometric was never meant to be just a custom motorcycle with an unusual appearance. It was conceived as a fully authored concept — a motorcycle in which shape, mechanics and visual rhythm all follow one clear internal logic. In Iron Custom Motors' own words, it is the materialized fantasy of a dreamer-engineer, brought to life in the pure language of retro-futurism.

The project achieved 4th place at the AMD World Championship of Custom Bike Building 2018 in the Retro Modified class. For a custom project, this is more than a result — it is confirmation that the motorcycle was recognized on one of the most respected stages in the international custom world.

The most iconic engineering feature of Geometric is its front wheel — the world's first spoked hubless wheel. This single solution is enough to make the motorcycle instantly recognizable. Combined with an early-production IZH-Jupiter engine integrated into an extremely compact architecture, a fully handmade dual-row chain, and custom sprockets — Geometric becomes a project where every part contributes to one consistent image.

For Iron Custom Motors today, Geometric remains one of the strongest examples of concept-driven custom work. It demonstrates the studio's capacity to think beyond categories and to execute motorcycles that challenge ordinary expectations not only aesthetically, but structurally.
