On this weeks program we start off discussing The Age article on safety concerns about on-street parking and Dr Cameron Munros findings on top risks to riders. Chris interviews Associate Professor Simon Batterbury about his experience and research on community bike workshops and his upcoming talk at Melbourne Uni where Simon explores community bike workshops that provide an 'urban commons' where people learn to fix up a working bicycle, and source their own parts and tools. Workshops operate on the ‘demand’ rather than ‘supply’ side of sustainable transport, creating skills and a bike culture, not infrastructure.  Talk details: 1pm–2pm, Tuesday 18 Aug 2015, Theatre 2, Basement, School of Geography, 221 Bouverie Street, Carlton. Local news includes the upcoming Melbourne Brompton Urban Challenge in October.
