This year's Velo-city 2015 European conference is in Nantes, France.
Nantes is a smart pick for a conference about liveable cities: Nantes won the 2013 European Commission award for green cities, and is renowned for its public transit and its 600,000 citizens are served by almost 800 kilometres of cycling tracks and three different bicycle share/rental companies.
Kind of sad that one of the first facts in the video promoting Nantes is that it's just two hours from Paris. Supper in Paris, sleep in Nantes, I guess.
