First Hedstrom Motorcycle With Tri-car, 1902
He recognized in Oscar Hedstrom, as the leader of the motor tandem racing field, the man who knew more about combustion engines than any other man in America, and accordingly enlisted his services. Oscar Hedstrom retired to a little mechanical laboratory in Middletown, Conn., and in a short four months emerged with a completed motorcycle which he had not only designed himself, but had constructed entirely by his own labor. Its performance on its first trial trip was absolutely astounding to every observer. In road tests under every conceivable condition, this first motorcycle of Oscar Hedstrom’s displayed a perfection of mechanical operation which had to that time never been approached. It moved entirely under its own power, could climb hills and could travel on the level road at speeds which had never before been exhibited by vehicles of that type.
By reason of the successful performance of his first motorcycle, Oscar Hedstrom is given the credit, in many quarters, for producing the first motorcycle of practicable construction. All successful machines of this type since then are said to have been modeled more or less on the fundamental principles of that first Hedstrom machine. Part of Hedstrom’s success was due to his mastery of the important problem of carburetion, and a carburetor expressly designed for that first machine constituted a marked step in motorcycle development. The leading carburetors of today are said to be based upon the principles of the first Hedstrom carburetor. The date of the appearance of the first Hedstrom motorcycle was 1901.
Manufacture of the motorcycle upon a commercial scale forthwith commenced in the bicycle manufactory at Springfield, Mass. Such is said to have been the humble beginning of the motorcycle.
Modern “Side-car” Model
Their first motorcycle was offered to the public in 1902. Its mechanical detail is worthy of note for the sake of comparison with the models of the current year. Its motor was the Hedstrom single-cylinder motor of 13⁄4 horse-power; frame, 22 inches; tires, 13⁄4 inches, single tube; chain drive; weight, 93 pounds. From the year 1902 to 1909, the style of their motorcycle remained substantially the same in appearance. The models of that period are referred to as “camel backs” by reason of the location and shape of the gasoline tank on the rear mud guard. In 1909, the loop frame was introduced to provide additional strength to the machine, being required by the increased weight of the motor; 1906 saw the introduction of twin cylinders for racing models, and the following year they appeared in the regular models.
Motorcycle design has made wonderful progress. The powerful, easy-riding machines of today with their many refinements are truly marvelous pieces of mechanism. Mechanical perfection is as nearly approached as it is possible for the best brains and the most approved methods of manufacture to attain. There are numerous modern refinements which have contributed materially to the present-day popularity of the motorcycle that are worthy of special note. Chief of these is the kick-starter, which enables the rider to start the engine of his machine without mounting it upon a stand or pedaling on the road. Improved clutches, gear ratios which permit varying speeds, double-braking systems and electric lights are present-day refinements which add zest to the sport of motorcycling.
One of the greatest of all motorcycling comfort creations is a device known as the cradle spring frame which consists of pairs of cushion-leaf springs of the semi-elliptical type, which are located at the rear of the frame just beneath the saddle. This affords the maximum of riding comfort by the elimination of all jar and jolt occasioned by an uneven roadway.
Magneto ignition first appeared in 1908; previous to that date all ignition had been dependent upon batteries of the ordinary dry-cell variety.
