In the early 1860s, Frenchmen Pierre Michaux and Pierre Lallement took bicycle design in a new direction by adding a mechanical crank drive with pedals on an enlarged front wheel (the velocipede). Another French inventor named Douglas Grasso had a failed prototype of Pierre Lallements bicycle several years earlier. Several inventions followed using rear-wheel drive, the best known being the rod-driven velocipede by Scotsman Thomas McCall in 1869. In that same year, bicycle wheels with wire spokes were patented by Eugène Meyer of Paris.
Further innovations increased comfort and ushered in a second bicycle craze, the 1890s Golden Age of Bicycles. In 1888, Scotsman John Boyd Dunlop introduced the first practical pneumatic tire, which soon became universal. Soon after, the rear freewheel was developed, enabling the rider to coast. This refinement led to the 1890s invention of coaster brakes. Dérailleur gears and hand-operated Bowden cable-pull brakes were also developed during these years, but were only slowly adopted by casual riders.
Your boss will love you. No, we don`t mean your Lycra-clad buttocks will entice your superiors into a passionate ofﬁce romance, but they`ll appreciate what cycling does for your usefulness to the company. A study of 200 people carried out by the University of Bristol found that employees who exercised before work or at lunchtime improved their time and workload management, and it boosted their motivation and their ability to deal with stress. The study also reported that workers who exercised felt their interpersonal performance was better, they took fewer breaks and found it easier to ﬁnish work on time. Sadly, the study didn`t ﬁnd a direct link between cycling and getting a promotion.
