The Circle City Bicycles blog contains info on bicycles, cycling events, pro racing, bicycle touring, and just about anything else cycling related. Since our bike shop is located in Indianapolis, we focus on biking in the Midwest, but cycling fans anywhere in the world should find this blog interesting. We try to post daily Monday through Friday, but we occasionally miss a day. Each Friday we try to have an interesting bicycle related photo.
Here's an interesting comtraption - the parabike. It has a helium filled balloon to provide lift. The pilot pedals, which drives a big fan behind him to generate forward thrust. When the rudder is applied, the balloon remains essentially stationary, while the bike rotates underneath it. There is also an elevator which allows the craft to go up and down.
