Two wheels - Chains, sprockets et design

The earliest known models of what would eventually become the bicycle were created in the early 1800's. The initial design featured a two-wheeled draisine, which the user would walk with in order to move it forward. Later iterations of the bicycle added pedals, which gave the device drastic new potential. Designs have further changed throughout the years, but the device itself has never fallen out of fashion. In fact, it seems that interest in cycling has reached an all-time high in recent years.Cycling has come to be more than simply a means of transportation these days; it has become a true lifestyle. And with that newfound popularity, an entire culture has emerged that explores the aesthetic and functional possibilities of the sport.
