Key Bike Rack.. The CHIAVE bike stand is made entirely in 7 mm thick zinced and polyester powder coated steel, with two key shaped pieces set side-by-side, spaced at 63mm by two stainless steel elements complete with antitheft fixings. This shape also includes a Ø 80 hole to allow a secure place to attach a lock and bike frame. Ground fixing is with a Ø 40mm end tube, rigidly welded to the structure, or with base plate and bolts (not included). Dimensions H 895mm, L 386mm.
Ai Weiwei’s most recent work, Forever Bicycles, installs 1,200 bicycles--some hanging from the ceiling, some standing upright on the floor--one behind the other. The bikes have no handlebars and no seats and instead use those parts of the frame to extend upward and outward to connect to other wheels and other frames, creating the illusion of a labyrinth-like space in a three-dimensional area.
