The dwarf ordinary addressed some of these faults by reducing the front wheel diameter and setting the seat further back. This, in turn, required gearing—effected in a variety of ways—to efficiently use pedal power. Having to both pedal and steer via the front wheel remained a problem. Englishman J. K. Starley (nephew of James Starley), J. H. Lawson, and Shergold solved this problem by introducing the chain drive (originated by the unsuccessful "bicyclette" of Englishman Henry Lawson), connecting the frame-mounted cranks to the rear wheel.
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.
Live longer. King`s College London compared over 2,400 identical twins and found those who did the equivalent of just three 45-minute rides a week were nine years ‘biologically younger` even after discounting other inﬂuences, such as body mass index (BMI) and smoking. “Those who exercise regularly are at signiﬁcantly lower risk of cardiovascular disease, type two diabetes, all types of cancer, high blood pressure and obesity,” says Dr Lynn Cherkas, who conducted the research. “The body becomes much more efﬁcient at defending itself and regenerating new cells.”
