Bicyclists will do well to meditate on the following ominous paragraph in the last London Truth: "it may be noticed that many young men you meet nowadays are prematurely round-shouldered and walk with bent knees and a sort of crab-like movement. This is not the result of over-study or weakness, but the consequence of perpetual wobbling on what is called the 'steel horse.' This peculiar and ungraceful appearance, which is becoming indelibly stamped on many youths, is known as the 'bicycle back.'"
Alas, bicycle back is not covered by Obamacare.
A pro-cycling magazine "The Wheel World" took a different bent to the issue
The wretched habit of riding with the body inclined forward has produced an habitual bent attitude with several riders, and given rise to a prejudice against the sport itself, as producing a " bicycle back." Nearly all oarsmen have this form of back, and it has not proved detrimental ; but it is ungainly, and the methods by which it is acquired on a bicycle are entirely unnecessary. Erect riding is more graceful, develops the chest, and add ; an exercise to the muscles of the throat and chest that rowing d )es not. The exposure to out-of-door air, the constant employment of the mind by the delight of changing scenery or agreeable companion- ship, add their contribution, and make bicycling, to those who have tried practically every other sport, the most enjoyable, healthful, useful exercise ever known.
There was also, it seems, something called "bicycle tongue" but I have no idea what that was.
