Beat illness. Is cycling good for you? Yes! Forget apples, riding`s the way to keep the doctor at bay. “Moderate exercise makes immune cells more active, so they`re ready to ﬁght off infection,” says Cath Collins, chief dietician at St George`s Hospital in London. In fact, according to research from the University of North Carolina, people who cycle for 30 minutes, ﬁve days a week take about half as many sick days as couch potatoes.
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.
The Svea Velocipede with vertical pedal arrangement and locking hubs was introduced in 1892 by the Swedish engineers Fredrik Ljungström and Birger Ljungström. It attracted attention at the World Fair and was produced in a few thousand units. By the turn of the century, cycling clubs flourished on both sides of the Atlantic, and touring and racing became widely popular.
