Bicycles 1 Today bicycles are so common that it s hard to believe they haven t always been around. 2 But two hundred years ago bicycles didn t even exist and the first bicycle invented in Germany in 1818 was nothing like our bicycles today. 3 It was made of wood and didn t even have pedals. 4 Since then however numerous innovations and improvements in design have made the bicycle one of the most popular means of recreation and transportation around the world. 5 In 1839 Kirkpatrick Macmillan a Scottish blacksmith dramatically improved upon the original bicycle design. 6 Macmillan s machine had tires with iron rims to keep them from getting worn down. 7 He also used foot-operated cranks similar to pedals so his bicycle could be ridden at a quick pace. 8 It didn t look much like a modern bicycle though because its back wheel was substantially larger than its front wheel. 9 In 1861 the French Michaux brothers took the evolution of the bicycle a step further by inventing an improved crank mechanism. 10 Ten years later James Starley an English inventor revolutionized bicycle design. 11 He made the front wheel many times larger than the back wheel put a gear on the pedals to make the bicycle more efficient and lightened the wheels by using wire spokes. 12 Although this bicycle was much lighter and less tiring to ride it was still clumsy extremely top-heavy and ridden mostly for entertainment. 13 It wasn t until 1874 that the first truly modern bicycle appeared on the scene. 14 Invented by another Englishman H.J. Lawson the safety bicycle would look familiar to today s cyclists. 15 .
