Treeriding bicycle tubes of Warsaw is a bit of manifesto and real solution for the car crowded and overloaded city. Because of incompetence of city urban planists who not able to redevelop and combine together cars and bicycles infrastructure, so that the best solution is to pull up the bikes up in the air. Design proposal consists of simple tree structure of the columns that support bicycle lane, all is connected with the ground by the spiral tubes every few kilometers. Outter shell is made by self- closing membrane which is sensitive because of the weather conditions such as rain, wind and sun overload. The aim of the tubes is to connect each SENW part of the city, and then expand the net by circular grid. The whole structure creates the impresion of lightness and fluidity.
