==Course Title==
A bicycle, or bike, is a small, human powered land vehicle with a seat, two wheels, two pedals, and a metal chain connected to cogs on the pedals and rear wheel. A frame gives the bike strength, and all of the parts other than the frame are attached to the frame. The name comes from these two wheels - the prefix "bi-" meaning two, and the suffix "-cycle" meaning wheel. It is powered by a person riding on top, who pushes the pedals around with his or her feet.

Electric bicycles have been around for awhile and have had varied impact in different societies as the technology has advanced. Once example is the new [http://yikebike.com/ Yike Bike] that will be available in class. 
The rear derailleur is the parallel linkage at the back of the bike which uses springs and wheels to change gears. The mechanism works by "derailling" or forcing the chain sideways from one sprocket to the next. For more details on the derailleur, click here: [[Bicycle_Derailleur]]

The front wheel of the bike is connected to the fork, which is in turn connected to the frame of the bike via the head tube. Different mechanisms are used to attach the wheel to the fork, but the most commonly used method is by a quick release system.  The handle bar is connected to the fork inside the head tube to allow rotation of the fork/front wheel for steering. A number of configurations for the handle bar and fork have been developed to accommodate the needs of different riders.
