G. F. Perkins & Co., of Haydenville, Mass., advertise to furnish a velocipede with steel springs for $40. We do not know that their machine has been fairly tested. We have never seen it in use, and are unable to speak of its merits. Among the latest improved machines, is one manufactured by Messrs. Tomlinson, Demarest, & Co., No. 620 Broadway, New York. It is called the “Improved American Velocipede,” and differs from styles best known to the public in important respects. It is the recipient of many encomiums from those who have learned to ride it. The iron arms, between which the front wheel is held, are inclined back at an angle of forty-five degrees from the perpendicular, which inclination brings the seat in such a relative position to the fore wheel, that a man of medium height can, with his feet, reach the treadles of one of these velocipedes, the front wheel of which is forty-five inches in diameter, with as much ease as he can those of the ordinary velocipede, the fore wheel of which is of a diameter seven or eight inches smaller. This peculiarity gives likewise great facility in describing sharp curves and circles of small diameter, the body being inclined in the direction in which the rider wishes to propel himself, and in the direction in which the driving wheel is inclined. Those who have become expert in the use of this new machine, claim that the movement of the body in propelling and guiding it, is more nearly analogous to that of skating, than is employed in controlling the ordinary bicycle. Indeed, they claim that it can be guided by the mere inclination of the body without perceptibly varying the pressure upon the handles to the one side or the other. The peculiar rakish arrangement of the standard, prevents the usual jar to the guiding arms in going over rough ground and pavements, and allows the wheel to turn without soiling the pantaloons. It is claimed that this machine can be driven at great speed, and up steep grades. * * * * * Messrs. Pearsall Brothers, of New York, have patented a bicycle which is so constructed that the rear wheel is used as a guiding wheel. This machine will turn a quick corner, and can be ridden rapidly. Its price is $125. * * * * * Stephen W. Smith, of 90 William Street, New York, manufactures a velocipede for boys, with a guiding wheel twenty inches in diameter, for $25. The saddle of this machine is so wide that but little balancing power is requisite, and any child can easily learn to ride it. THE DEXTER BICYCLE.
