Once upon a time, the main danger associated with bicycling had nothing to do with being hit by a car.
Instead, some late 19th century doctors warned that — especially for women — using the newfangled contraption could lead to a threatening medical condition: bicycle face.
"THE UNCONSCIOUS EFFORT TO MAINTAIN ONE'S BALANCE TENDS TO PRODUCE A WEARIED AND EXHAUSTED 'BICYCLE FACE'"
"Over-exertion, the upright position on the wheel, and the unconscious effort to maintain one's balance tend to produce a wearied and exhausted 'bicycle face,'" noted the Literary Digest in 1895. It went on to describe the condition: "usually flushed, but sometimes pale, often with lips more or less drawn, and the beginning of dark shadows under the eyes, and always with an expression of weariness." Elsewhere, others said the condition was "characterized by a hard, clenched jaw and bulging eyes."
It's hard to find the very first mention of this "condition," but in an 1897 article in London's National Review, British doctor A. Shadwell claimed to have first coined the phrase a few years earlier. He went on at length about the dangers of bicycling, especially for women, describing how "cycling as a fashionable craze has been attempted by people unfit for any exertion."
Descriptions of bicycle face varied: some implied it could be a permanent condition, while others maintained that, given enough time away from a bicycle, a person's bicycle face would eventually subside.
Explanations of the root cause of bicycle face also vary. Shadwell, for one, argued that the particular difficultly of keeping a bicycle balanced causes it, but that the accompanying overexertion also plays a role. Some other publications felt that violating the Sabbath by riding bicycles on a Sunday was ultimately to blame. Most publications agreed that bicycle face could strike anyone, but women were disproportionately affected.
Obviously, bicycle face isn't a real thing. That brings up an interesting question.
IN THE 1890S, BICYCLES WERE SEEN BY MANY AS AN INSTRUMENT OF FEMINISM
As Munsey’s Magazine put it 1896: "To men, the bicycle in the beginning was merely a new toy, another machine added to the long list of devices they knew in their work and play. To women, it was a steed upon which they rode into a new world."
All this triggered a backlash from many (male) doctors and onlookers, who cited all sorts of reasons to dissuade women from riding bikes. In general, they argued, bicycling was an excessively taxing activity, unsuitable for women — it would not only lead to bicycle face, but exhaustion, insomnia, heart palpitations, headaches, and depression.
The women who did ride faced a huge list of rules. Among the New York World's 41 rules for female cyclists printed in 1895: "don't refuse assistance up a hill" and "don't emulate your brother's attitude if he rides parallel toward the ground."
Towards the end of the 1890s, though, many doctors began to publicly question the idea of bicycle face, noting that people concentrate when riding or driving any sort of vehicle without it causing lasting facial damage.
In 1897, The Phrenological Journal quoted Chicago doctor Sarah Hackett Stevenson putting the issue to rest: "[Cycling] is not injurious to any part of the anatomy, as it improves the general health. I have been conscientiously recommending bicycling for the last five years," she said. "The painfully anxious facial expression is seen only among beginners, and is due to the uncertainty of amateurs. As soon as a rider becomes proficient, can gauge her muscular strength, and acquires perfect confidence in her ability to balance herself and in her power of locomotion, this look passes away."
