Women cyclists, naturally enough, saw an opportunity to support a good cause that everybody in Iran could agree on: clean air. After all, there is no law in Iran that officially forbids women to cycle.But when women in Marivan, a city in west Iran, took to their bikes.
they were arrested by police – despite having explicitly followed the advice of the local authorities to cycle instead of drive.They were released the same day, but only after signing pledges to not ride bicycles again. Marivan residents later protested in an open letter to local authorities.
Shortly afterwards, Iran’s vice president for women’s affairs, Shahindokht Molaverdi, posted a photograph of women cycling on her official Twitter account. Under it, she quoted the country’s supreme leader, Ayatollah Ali Khamenei, as saying: “Women’s cycling is permissible on the condition that religious customs are observed.”
Subsequently, in an article in the pro-government Tehran Times, a female journalist quoted a government official who supported female cyclists, and concluded: “As long as there is no violation of the dress code, women should be free to ride bicycles on the street.”
