Roma Ciclofficine popolari (Network of People’s Bike Kitchens) is a network of bike-activists engaged in what in Rome could be considered a grassroots movement: promoting daily use of the bike. Each Ciclofficina (workshop) provides people with a place to fix their own bike (or learn how to) for free. As a network, we organize collective actions like promoting big auctions of bikes, bike-mechanic courses, and building DIY bike lanes. We also encourage people to start more Ciclofficine popolari, offering them practical help. The network was launched in 2008, when Ciclofficine popolari began to spread around the city; today in Rome there are 10 Ciclofficine. One more will open the last Friday of September 2012, for the 20th anniversary of San Francisco’s Critical Mass.
