Vienna City Bike
Lonely Planet review for Vienna City Bike
Everywhere you go in Vienna you’ll encounter stands with bicycles provided by the City of Vienna to promote cycling in the city; currently more than 60 of these bike stands are scattered throughout the city. A credit card is required to hire bikes; just swipe your card in the machine and follow the instructions (in a number of languages). Keep in mind that these bikes are mainly for use as an alternative to transport (they can only be locked up at a bike station, unless you have your own bike chain, of course). A lost bike will set you back €600.
