Read the rough-draft summary of Chapter 4 of Wheels of Change.

1 Bicycle racing became popular almost as soon as the first bicycle was introduced in 1878. 2 Although most racers were males, many females soon entered this growing sport. 3 It was not long before races began to occur throughout the United States, attracting large crowds of fans who applauded the competitive efforts of these female athletes. 4 However, despite their determination and successes, not everyone in the community was supportive of women racers. 5 Some believed that women’s place in cycling was “not on the public race path,” and many tried to make it difficult for women to compete. 6 Ultimately, these attempts were too late and largely unsuccessful, and women racers continued to make their mark in the cycling world.
