Dr. Benjamin Ward Richardson of Great Britain, a big fan of the wheel, nevertheless summarized its pitfalls in his 1895 article "What To Avoid in Cycling."

to persuade young readers to avoid riding bicycles until they are older

to entertain readers with a story about a doctor who was against cycling

to inform readers about one reason why cycling was controversial in the 1800s

to emphasize that the advantages of cycling are not worth the risks
