If any of our readers desire the luxury of a ride on a velocipede without the necessity of taking lessons, or the danger of getting a fall, they will find " Bradford's Four-Wheeled Velocipede" ready and able to afford them the pleasure. The inventor of this vehicle, Mr. C. K. Bradford, has devoted the greater part of the last five years to experiments upon the velocipede, and took out his first patent three years and a half ago. The machine, as now constructed and improved, obtained its American patent October 13th, 1868. It has since been patented in England, France, and Belgium. It is made of the best material, and finished like a gentleman's trotting wagon. It weighs but sixty-five pounds, and combines in a high degree both lightness and strength. Any man, woman or child, can learn to guide it easily with but a few moments practice. The inventor claims that it is able to maintain a speed of a mile in three minutes, and that the extraordinary time of a half mile in one minute and forty-five seconds, has been made upon a country road. It can be driven by almost any man, at the rate of a mile in four minutes, on almost any road, without greater exertion than is ordinarily used in walking. This velocipede, unlike all others, is seen to best advantage on the street. In Mr. Bradford's tasteful little curricle, the rider can sit at ease as carelessly as in a carriage, giving himself up wholly to the exhilaration of the rapid movement, and the pleasurable exercise of the muscles, which is just enough to make the machine skim over the ground, and give an enjoyable sense of power. The increase of friction, which would naturally result from the additional number of wheels, is prevented by an application of anti-friction rollers, which reduce the labor of propelling the machine to a minimum, a requisite of the highest importance to a person seeking either recreation or utility.
