I wish upon every star in the sky that Atlanta could get CityBike kiosks throughout our fair city. Possibly the greatest thing ever! You use a credit card to register, it costs 1 euro for registration, and after that you just use your card to then rent a bike. The first hour is always free. You can return the bike at any city bike location and there are something like 50 or more locations throughout the city. Almost every underground stop has one outside of it, as do most of the main tourist attractions. The only problem I came across was getting to a stop and there being no spaces available to put your bike. That means biking to the next closest location and leaving it which does add a bit of time. Oh well. It's still the best thing ever! read more
