Вторсырья псто...


Гретатунгберисты много говорят о экологии и ничего не делают, ведь главное призывать, правильно? А вот нормальные инженеры периодически делают. Молча.

this single speed city bike is made with various recycled plastics using injection molding technology. compared to the construction of the traditional metal bicycle, this process is less labor-intensive and more accessible: it can be customized to characteristics of local industry– its abilities, advantages and disadvantages.


to construct ‘frii’, bearings are inserted into the mold before injecting, and tires are ‘full’ material, injected over the rims, making them ‘flat tire’-proof. the saddle is injected in different sizes to accommodate various heights of riders. this alternative material dictates a new aesthetic as well: ‘frii’ features smaller wheels, 20 inches in size, which calls for a shorter fork and adds strength. additional strength is created by plastic ribs, which are used throughout the design. the frame also includes a pyramid-shaped bottom by the crank for stability.
Понятно, что ПЭТ и производные таком образом утилизировать не получится. Но большинство термопластов выдерживают как минимум два-три цикла переработки без значительного ухудшения механических характеристик.



А конструктив позволяет нивелировать основные слабости пластиков. Браво!
P.S.
И расцветочка задорная!
