The Ajiro Bamboo Velobike: Grown Not Made

Australian design student Alexander Vittouris has managed to not only design an all-bamboo velobike, but has also incorporated the natural growth process of bamboos in the design of a fully sustainable vehicle, the Ajiro Bamboo Velobike.

The Monash University student's design was a finalist at the 2011 Australian Design Awards. He uses the term 'growth mobility' to describe the incorporation of the "strength and rapid growth of bamboos" in the final structure of his design.

Vittouris borrows from the principals of arborsculpture, or 'tree shaping' techniques, whereby the shape of a tree or plant is controlled and instructed by various techniques (leaf trimming, wiring and pruning, for example). In this case, Vittouris has used an inner skeleton structure that the bamboo grows around.

He says the manipulation technique used becomes economical and environmentally-friendly, in comparison to the cost of metal and energy exerted in assembling a traditional bicycle frame.

In his Australian Design Awards entry, he writes: "The skeleton frame is then proposed to be reused, for future plant generations as an ongoing cycle. In this case, the manipulation and intervention is more akin to a farming process, whereby bamboo plants need time for thorough establishment to form the required energy mass to produce new culms."
