It is impossible for an adult to sit on a bicycle without looking the fool. There is a type of woman, in particular, who should never assume the bicycling posture. This is the woman of ample proportions. Standing on her own feet she is a figure to admire-classical in her beauty and a symbol, throughout history, of sensuality, maternal virtue, and plenty. Mounted on a bicycle, she is a laughingstock.
Bicycles are top-heavy, have poor brakes, and provide no protection to their riders.
Bicycles are also made up of many hard and sharp components which, in collision, can do grave damage to people and the paint finish on automobiles. Bicycles are dangerous things. Of course, there's nothing wrong, per se, with dangerous things. Speedboats, racecars, fine shotguns, whiskey, and love are all very dangerous. Bicycles, however, are dangerous without being any fun.
