Conceived by designer Ionut Predescu, the concept “Wire Bike” offers a new approach to designing a bicycle frame ultra-light based on the principle of tensegrity architecture that allows, when connected by bars cables without directly connecting bars between them to form a rigid system. Discovery!
Original description of the designer
High strength tensegrity frame made of carbon fiber and Kevlar cables. A Balance Between compression and tension elements Is Able to offer a lighter alternative to traditional bike frames by Producing a stiff structure elements WHERE Seem To Float One Against the Other.

Terms of architecture, which is the invention of Richard Buckminster Fuller in 1949, the word “tensegrity” is a contraction of the term “tensile integrity ” and characterizes the ability of a structure to stabilize by the forces of tension and compression and distributed it to them trim. The structures established by the tensegrity are stabilized, not by the strength of their individual components, but the distribution and balance of mechanical stresses in the entire structure. And a mechanical system comprising a discontinuous set of compressed components within a continuum of components tense, may be in a state of self-stable equilibrium.
For example, geodesic domes, such as the Geode in Paris (Fainsilber, 1985), are tensegrity structures where tensile forces are rearranged to minimize the distance between two points of the structure.

The simplest definition of a tensegrity structure:
In all structure, tension is used to hold the parts together.
In a tensegrity, tension is also used to hold the parts apart.
In the wire bike, there is no connection between the seat tube and the top tube of the bicycle.
The hub and rim of a bicycle wheel are a common example of tensegrity: the spokes are at tension; they maintain the separation of the hub and the rim with far less material if the spokes were at compression. Fuller notes this evolution of the wheel from spokes in compression to spokes in tension. His student, Harvard Professor Amy Edmondson, describes the behavior on <a href="http://books.google.com/books?id=F6n2dZJ1POwC&lpg=PR1&dq=a%20fuller%20explanation&pg=PA278#v=onepage&q=wheel&f=false" title="p. 278 of 'A Fuller Explanation'".

wow great….you know more about it…thanks alot…I’ve got new lesson from you…
