The Wood Brothers’ velocipede, though very similar to the French machine, is made of better material, with steel tires and axles, and with gun-metal gearings upon the rear wheel. This machine combines in a great degree lightness and durability. It weighs from fifty to fifty-eight pounds, and if required, can easily be led, lifted, or even carried by the rider. The seat is fixed more directly over the stirrups than in some machines, and at such a height above the wheels as to avoid wear and tear of the clothing from contact with mud and dirt, and the driving wheel in turning. The stirrups are attached in such a manner to the crank, that they can be adjusted near the hub or axle, giving speed on level roads; or they can be placed at the end of the crank, giving power and ease for rough roads and ascending grades. Two kinds of stirrups are used; the “spool pattern,” entirely round, and covered with leather, making it easy for the beginner to keep his foot in place; and the French swing stirrup, which is for proficient riders and general use. This latter style has a very long bearing, relieving the strain on the ankle joint, and making it easy to ride a distance without fatigue. This bicycle has a brake, rests for the feet in front, and a handsomely finished saddle, supported by steel springs. It will ascend a grade of one foot in twenty. The price is $135. The Wood Brothers have in their possession the first velocipede ever brought into this country. When first exhibited on the sidewalk in front of their warerooms, it attracted such attention that the police requested them to remove it. They have just completed for a New York gentleman, at a price of $300, one of the most completely finished velocipedes yet manufactured in America. THE MONOD VELOCIPEDE. Messrs. Mercer & Monod, of 54 William Street, New York, manufacture their velocipedes after a model of their own, which has its advantages, and embraces many of the best points of the French machine. The steering post is inclined backward, which brings the handle within easy reach of the body, and the whole machine under perfect control; and gives it a particularly rakish and natty appearance upon the road. The saddle can be adjusted backward or forward, according to the length of limb of the rider. Messrs. Mercer & Monod use the triangular beveled treadle and an improved brake. The defect of this machine is its weight, which is about seventy pounds. Some riders, however, prefer a heavier machine than others, and recommend the Monod velocipede on this account. A good rider on this machine can obtain a speed of ten or twelve miles an hour. It varies in price from $110 to $150, according to finish. These gentlemen have lately manufactured some very complete machines for country use, with shawl rack, mud dasher, etc. WITTY’S VELOCIPEDE.
