Paris Breaks by Bicycle
The Velib or Velo Libre free bicycle rental scheme is now massive in Paris. It's a great way to get around in the city and after taking out a nominal one euro per day subscription, each one way rental is completely free as long as you complete the journey withing one half an hour. That should be long enough to get where you want to be and you don;t need to worry about finding another bike to get back again because they are everywhere.
