One of the centrepieces of Andy Warhol | Ai Weiwei at the National Gallery of Victoria is a fresh iteration of Ai’s Forever sculpture. Located in the foyer, the sculpture consists of a towering arch of over 1,500 interconnected bicycles, all uniformly produced to a minimalist design. The Forever series is now among Ai’s most known works, having been exhibited in many configurations in museums and public spaces in London, Taiwan, Taipei, Venice and Toronto and elsewhere. The namesake is China’s Yong Jiu (which translates as“Forever”) brand of bicycle. Established in the 1940s, the prized Forever brand dominated China’s cycling culture for several decades before the car became more widely used. For Ai there is a tainted nostalgia about the Forever bicycle. In the remote village where he was raised after his father – an enlightened and popular poet – was exiled from Beijing, the bicycle was not only needed for travel but for transporting things. It was also out of reach to all but the well-off, a high status object of intense desire for a child like Ai living in poverty.
