Since 2007, Vélib has been changing the transport grid in Paris and inspiring cities around the world to do the same. With 20,000 bikes and 1,800 bike-hire stations, it’s hard to miss this Parisian sensation. Vélib is now moving into uncharted territory – a bike hire programme for kids. The so-called "P'tit Vélib'" will offer some 300 bikes available in four different sizes (and helmets) for kids 2-10 years old. This is the first such programme in the world to do so, but certainly a trend to follow.
