Bicycles first hit the streets in the 19th century, and since then, the basics of the bike haven't changed that much. At its simplest, it's just a chain, crank, two wheels and some forward motion.
What has changed: taste and technology. Today's sophisticated machines are designed to fit any lifestyle -- sometimes with a price tag that rivals that of a small car.
WBOI's Julia Meek met with Tim Wegner and James Holm of Summit City Bicycles and Fitness to learn more about how the bicycle -- and cycling itself -- has evolved over the years.
