For those of you who want to use the Vélib bike system in Paris, the rates have just gone up.
The daily rate is now 1.70€ instead of 1€.
The weekly rate is 8€ instead of 5€.
However, there is a new innovation which should solve the "American problem" (no chip & PIN). The "Vélib Visit" system allows you to prepay your temporary tickets over the internet (including the non-debited 150€ guarantee) with your Visa or Master Card. You'll receive your "ticket number" by email, and then the last formality is to validate the "terms and conditions" the first time you use a bike station.
You will pay absolutely nothing more for using the bikes as long as you respect the 30-minute time limit. Be very careful hitching the bike to a post when you return it and ALWAYS wait for the green light and double beep. For added security, you can ask the station machine for a return confirmation ticket.
