Velib Bike Hire

I have just got back from a family Easter Holiday in France.  Yesterday we stopped in Dijon for lunch.  Opposite the restaurant was this rack of Velib bicycles.  It is not just Paris but virtually any French city of any consequence that has this scheme.  Looking at the instructions one week's subscription to the scheme could be had for one euro; then any hire of under half an hour (more than enough I would think to cross Dijon) was free.  The machines look practical and sturdy with an interesting shaft drive rather than chain connecting pedals and rear wheel.  I would have loved to give one a go but will have to wait for the London scheme to launch this July.  Naturally the success of these schemes depends upon not finger pointing at cyclists who choose not to wear helmets.
