Paris France just placed 10,000 bikes in its city for public use. Placed at over 750 bike pickup locations, bikes can be rented by the hour, with increased costs for time used (encouraging fast turnover of bikes so they're mostly used for short trips).
Bikes can then be returned to any service point so one-way trips are no problem...and locations will be close to major public transportation routes.
Paris officials think it will help their citizens navigate around the city (as bikes are better than public transit for shorter trips) and will help keep their citizens fit.
This is an interesting idea for Kansas City -- especially in leu of having a well-developed public transit system. Granted, a lot of work needs to be done to improve the bike-friendliness of our city and I have no idea how they plan to prevent the bikes from being stolen...
