PREFACE.

Table of Contents

To the Cyclist who appreciates the advantage of understanding his wheel, its mechanism and its construction, for the same reason and because of the same interest felt by a horseman in his roadster, an engineer in his locomotive, or a yachtsman in his boat, the following pages can scarcely fail to be of interest and value.

Bicycles without number have been consigned to the scrap heap or discarded for new mounts, as the result of abuse and the lack of proper care, due solely to the ignorance of riders as to a wheel’s construction and requirements, while disappointments have resulted, in many instances, because the same lack of knowledge has prevented the wise selection of a well constructed and properly adjusted mount at the outset.

A bicycle can no more be expected to run smoothly without a proper adjustment of its parts and their maintenance in perfect running condition than can any other piece of machinery, and while the chain and chainless productions of 1898 are admirable for their simple mechanism, such points as the bearings and running gear require periodical inspection and attention to insure satisfactory service. This cannot be adequately given by a rider who has no conception as to the details of construction of his machine, and so it frequently happens that a bicycle sinks into an early grave because its rider persists in calling upon it for continued service, while utterly indifferent to its construction and requirements.

Know thy wheel is an excellent maxim for every rider to follow; for those who heed it the matter of emergency repair will be a simple thing, a smooth running wheel will be assured, the chance of accident reduced to the minimum, and the life of the machine extended throughout its fullest period. It is partly with a view to bringing about a better acquaintance between the average rider and his wheel that the following pages are presented.

To the bicycle manufacturer and to the repair man and dealer—who are frequently called upon for advice and service concerning any and all makes of wheels—to the student of cycle construction, and to the mechanical expert, the volume will scarcely fail to be regarded as a valuable reference book for many years to come.

The idea of presenting to riders—through the columns of The Commercial Advertiser—an illustrated description of the lines, parts and improvements of the bicycle for 1898 was conceived chiefly because of the absence during the winter of 1897-98 of a National Cycle Show. Just prior to the opening of preceding seasons tens of thousands of riders throughout the country were able to see at the annual shows, and at those held under the auspices of the various local cycle trade organizations, all that the maker had to offer in changes and improvements for the new year. This opportunity was also furthered by the columns of descriptive matter published by the daily press and cycle trade journals in their reports of these shows and their exhibits. Riders were to have none of these advantages for the season of 1898, however, and The Commercial Advertiser accordingly began the work of collecting and presenting the information which appeared in its columns in serial form during February, March and April of 1898, and which is now presented in this volume.

It is not claimed that all of the new features and changes evolved by the master mechanics of the cycle building industry have been embodied. It is believed, however, that none having an important bearing upon, or any way likely to cause material changes in, the methods of bicycle construction have been overlooked. Further than this, the gradual processes through which these changes and improvements have been evolved are shown throughout the periods of distinct advancement, also those of reversion, as they have followed, one upon the other, until the present state of the industry is reached, and its product set forth as the most advanced, from every standpoint, in the history of bicycle building.

Likewise the progress and improvement made in the manufacture of tires, saddles, lamps, bells, brakes, and the many other articles common to the well-equipped modern bicycle, have received careful attention, with the result that the work of presenting this amount of information to the readers of The Commercial Advertiser has, we believe, been as complete and thorough as it has been practicable to make it.

NAMES OF THE PARTS OF A BICYCLE.

CHAPTER I.

EVOLUTION OF THE BICYCLE—1816 TO 1899.

Table of Contents

The nothing of the day is a machine called the Velocipede. It is a wheel carriage to ride cock-horse upon, sitting astride and pushing it along with the toes, a rudder wheel in the hand. They will go seven miles in an hour. A handsome ‘gelding’ will come to 8 guineas; however, they will soon be cheaper unless the army takes to them.—Letter of John Keats to a friend, about 1818.

The future historian of cycledom will clearly note that 1898 was memorable for the reincarnation of the chainless; that the chain models were improved in quality and reduced in price, and that the trade did not hold a show, this being the first lapse since those events began in this country in 1890. Conservative old England, where shows were first held and the bicycle really began to succeed, has just closed her twenty-first or coming-of-age show in London, and the other large cities of the kingdom are, in their turn, pushing the show around the circuit as usual. America—progressive and enthusiastic—after less than one decade of it, exhausted itself for the time, and the National Board of Trade of Cycle Manufacturers decided to pass 1898, refusing to give sanction to either national or local exhibitions.

From the stand of the riding public much might be said on the affirmative side of the show question. The show brings under one roof all the new models and accessories for the coming year, affording ready means of comparisons, instructive, even if sometimes odious; maker and rider come together, and the latter especially, has opportunity to renew old friendships; the copious reports and illustrations in the daily and trade press arouse expectation in the cycling public, and undoubtedly make many new converts; the gap between riding seasons is bridged across the winter of our discontent, and things are kept on the move. Not denying aught of this, the makers reply that they are not in the amusement business; that this is a costly form of advertising directly, also delaying trade both by inducing buyers to wait to see it all and by tying up their representatives when they ought to be on the road visiting agents; that no other business has or needs such gatherings; and that shows were originally intended to bring together maker and dealer, not maker and rider.

Intelligent and impartial observers who have studied the question from both sides, say that all the trouble has come from the American habit of overdoing, and that the makers are to blame for deviation from the original idea, and for going into gorgeous competitions in electric lighting, costly furnishings and decorations and a prodigal waste of printed matter; that when aisles are packed and the week is a society event, the greatest thing in a show, the one chiefly cared for, and really about the only one that can be seen, is the show itself, the crowd itself being what the crowd attends; that the thing becomes a grab for souvenirs and a spectacular waste, instead of an exhibit of cycles and accessories to those who really want to see them.

TRANSFORMATION OF THE SHOW.

Table of Contents

There has been a divergence from the original idea, certainly, even in England. The Stanley Show was at first the happy thought of some member of the Stanley Club, one of the oldest if not quite the oldest of cycle clubs, in a time of cycle feebleness, when the young sport needed all the aid it could command. To help things along through the winter, and doubtless largely on the strictly social side, it was proposed to get together in one place as many patterns of cycle and as many kindred articles as could be got. From that feeble start the thing has grown, as cycling grew. In a like feeble way, though with a model to follow, cycle showing began in this country, at Philadelphia. During the years that have followed it has brought the public into line, until in New York there is now only one building large enough to hold it—and that none too large for such an event. In Chicago there was one vast enough, but so vast that it had to be placed so far away from business and residence that it was as if a show were to be held out at Jamaica, on Long Island. Reaching the spot was certainly none too easy, and the cold was apt to be very bitter. Here in New York, it is urged, had the makers, through the National Board, chosen and decided to revert to the plan of a simple trade exhibition, and had the date been in November or December, instead of January or February, the cost would have been small, and all interests really concerned would have been benefited, even while allowing, although not pressing, the public to attend.

A CYCLE OPENING DAY.

Table of Contents

It is to be expected that shows will come again, with some lessons learned and surer warrant of having the net balances more on the right side all around. Meanwhile, and as an immediately timely matter, observe that cyclists have from the first gradually taken as theirs all seasonable outdoor holidays, and a sensible custom has grown up in Boston and other New England towns of making Washington’s Birthday, Feb. 22, an opening day among the retail cycle dealers, who hold open house, utilize flowers, decorations and other pleasant things; array their new models for view and invite the public to call. Needless to say, the invitation on this cycle New Year calls day is largely accepted and cyclists, real and expectant, with their sisters and their cousins and their aunts, go the rounds at pleasure, comparing models, anticipating the full riding season and enjoying good cheer.

THE DRAISINE IN ACTION—1818.

The retail cycle dealers in New York, lesser and greater, propose to adopt this good Yankee custom hereafter and will keep latchstrings out on Feb. 22, so that instead of one great central show there will be a thousand miniature ones scattered throughout the metropolis; it is estimated—of course there can never be an accurate census—that there are 250,000 cyclists in New York City alone. The 17th of March, St. Patrick’s Day, has generally been considered the opening of the riding season, the round of day and night being then equally divided: the opening day adopted for Feb. 22 will naturally and easily fall in with this customary notion as to March 17.

THE SWIFT MARCH OF IMPROVEMENT.

So rapid has been the march of improvement in cycle-making during the last seven years that the approach to fixity and uniformity of pattern—all bicycles now looking alike to the casual glance—has almost lost to us one of our most charming senses, the sense of delighted surprise. The most ingenious efforts of our master mechanics, accomplishing what would have been impossible only a short time ago, are now received as matters of course. The crude conditions and mechanical product of no more than ten years ago are rarely recalled; the vast majority of riders do not even know about them. The strength, lightness and beauty of the later bicycle have come out of long and toilsome and costly evolution, in which many have fallen by the way, and reward has not always been according to real merit. The careful student of the principles of cycle construction—the making of a poem of steel—cannot appreciatively examine the details in the advance shown in this year’s models without being glad that he is permitted to see such achievements. It is one thing to push and misuse the bicycle, another to ride it with intelligent care, another to understand it, another to love it and to honor the long cumulative skill which has made it possible and practical. The rabid seeker for extreme and radical novelties in type, form and modes of propulsion may care little for the niceties of mechanical accomplishment and may declare that the standstill has been reached. But this pessimistic and blasé view is unwarranted, for undoubtedly many of the most perfected and nearest perfect details now in vogue will be used on the cycle of the future, regardless of its general type.

THE TENDENCY TO FIXITY.

Table of Contents

As in a number of past years, the art of cycle-making in 1898 exhibits distinct signs of two irresistible tendencies. One is toward fixity of type; the other is toward reversion to type. Fixity of type means the condition when—although there may be several widely different patterns of bicycle in use, as there always are of other wheeled vehicles—all of one pattern are substantially alike, varying only in trivial details, the product of all makers bearing the same appearance to the casual eye, however varying in real quality. When that time comes bicycles will resemble cut nails in being staple, standard, uniform and all alike. Such a time has not yet arrived, and it is not necessary to try to name the date in the new century when it will arrive; nevertheless the signs of its approach are unmistakable.

THE TENDENCY TO REVERSION.

Table of Contents

Reversion to type—a well-known phrase of the scientific evolutionist—means here a return to earlier and once-discarded forms of construction. Very few notice the process, yet it constantly goes on. The inquirer for novelties often has the old presented to him and is satisfied, supposing he is looking on a new up-to-date production; it is a common experience to find alleged new devices brought out and rapturously received by the quidnuncs which the veteran instantly recognizes as among the things he saw tossed, years ago, into the refuse of the scrapheap.

That unhappy and irrepressible person, the born inventor—one of whom, like the sucker, is born every minute—is perpetually doing this in cycle matters, because the cycle is so much in the public eye that it draws him as the lamp flame draws the moth; he cannot keep away from it. Twenty years ago, at the very beginning of the bicycle in this country, he was eagerly on hand with his multiple-speed, mile-a-minute contraption; he has been doing the same ever since, and is just as industriously as ever reinventing the old folly; the Patent Office is flooded with his lumber. This, however, is repetition rather than reversion.

Reversion to old forms comes about for several reasons. We must always remember that the bicycle, like the piano, the violin and some other things which could be cited, belongs to nobody. Nobody invented it; it is the product of many minds, and has been wrought out by a long and gradual evolution, in which every step, freaky ones excepted, has been suggested and tested by practical use. Hence a device may be abandoned in the hope of escaping the inevitable drawback which besets all earthly things; or a device may be dropped because it cannot be made well enough or easily enough in the existing state of the art; or the conditions of public demand, or the state of the roads, or the caprice of fashion may change. Changes also come about to gratify the craving for novelty, and when the list of possibles comes to its end the maker goes back to or toward the beginning again, like the preacher who tips over his barrel of sermons and starts in afresh on the other end.

THE ORDINARY—1878.

For illustration, suppose the following: The chain has some drawbacks, and therefore it is gradually displaced by the bevel-gear and entirely goes out. That gear develops drawbacks in turn, provoking fresh complaint, and after some years of suffering under it, some maker brings out a chain wheel, which is hailed with delight, and widely written up as the novelty of the year. One by one makers follow suit, until the gear is again quite displaced; improvement has then gone around and has come back upon its own path, the disadvantages of the old form having been found by trial to be less than those of the newer. This supposed case, which is partly real, would illustrate progress by reversion.

A BRIEF SKETCH OF DEVELOPMENT.

Table of Contents

The early history of bicycle development has been told even to weariness, perhaps because not always well told. We shall not go over the course again, and yet it may not be amiss to show briefly and connectedly how the wheel of today grew out of the three preceding ones, especially since this strikingly illustrates the reversion process just explained.

The earliest vehicle for making oneself horse as well as rider was a three-wheeler, and was known at least, as early as 1779; the two-wheeler began in 1816, as far as records show, with the Draisine, a front-steerer, which was all ready to develop into either a front-driver or a rear-driver, according to the method of attaching the cranks, which so long remained the missing link. Of course it quickly went out, and after nearly a half century of oblivion it was dragged down from the garret and the cranks were added—to the front wheel, as that was then the easier way. The revival is generally credited to France and to Pierre Lallement, although Michaux, for whom he had been working in Paris, is probably more entitled to the credit than he; the name of the man really the first to take the new step, however, is hopelessly lost in obscurity. Lallement did ride the thing in Paris, and did afterward make one in Connecticut. The patent on oppositely projecting cranks issued to him in 1866 became the most valuable one on which suits were afterward fought and royalties were collected, yet Lallement invented nothing, and it is worth putting on record here that Mr. Wilcox saw the velocipede of that day publicly ridden in Brooklyn nearly two years before the issue of that patent, and more than a year before Lallement came to this country.

A few years of decline as a curiosity and the "boneshaker had gone into forgetfulness after the Draisine. Aside from its intolerable weight and its crude and clumsy construction, what killed it was its lack of speed, for it was geared level, that is, not geared at all. England, however, did not give up the subject, but kept pegging away at it. To get a longer run for each foot-stroke, a larger wheel was necessary; so the rider was gradually brought over his work, and the front wheel became as large as he could reach, on a close built construction; necessarily the back wheel shrunk to a smaller size, ranging from 16 to 18 inches, or else the thing could have been neither mounted nor managed. Wood had given place to metal; the tubular steel frame, the suspension wheel with wire spokes, the steel rim and the solid rubber tire came in nearly together, and so, as the third great step, was evolved the high wheel, or the good old ordinary, still held more or less affectionately in the memory of all who ever rode it. A specimen or two appeared in the Centennial Exhibition at Philadelphia in 1876. In the following year the new type commenced to go in this country, beginning thus the bicycle era, and it made its pioneer way without any rival until 1881. In 1880, however, McKee & Harrington of this city, one of the pioneer makers, received a diploma and a bronze medal for a steel bicycle" exhibited at the fair of the American Institute. But the faults of the new construction were as positive as its virtues. It was heavy, averaging twice the weight of the bicycle of today; the size which fitted depended on the rider’s length of leg, not at all on his strength or his preference; worst of all, it was an acrobatic and unsafe thing, and was not a practical vehicle, although those who then sold and used it tried to make it out so.

Under the demand for safety, invention went back to the "boneshaker, and put on the cranks and sprockets which could have been put on earlier, producing in a clumsy form the now universal geared rear driver. An earlier specimen under the name of Bicyclette appeared as far back as 1879, but the Rover (nearly identical with that) succeeded in giving its name to the type. Yet this name failed to survive, because the type drove out every other, and no specific name was required to distinguish it. To the great majority of present riders, this is the bicycle, the only one they ever knew; before it had driven out all others it was spoken of as the safety," and yet there were many other forms of safety bicycles, of which one antedated the rear driver in this country by some six years, and two originated here.

All this was reversion to type. The Draisine went out of existence, then received cranks on its front wheel and revived as the boneshaker, or velocipede. That went out as quickly in its turn, and gradually grew into the ordinary. Then reappeared the Draisine, with cranks in the other places, and drove out the high wheel after a hard contest. Will any such complete reversion occur again? It does not seem likely; yet when we remember the long and persistent battle of the types, and the number of forms which have been tried, it would be unwarranted to pronounce this impossible; the front driver still survives, although little is heard of it, and if it should possess the field once more that would be no more remarkable than the changes which have already occurred.

TENDENCIES IN GENERAL.

Table of Contents

The mechanical tendencies of the American cycle makers and their product for 1898 are sharp and clearly defined. Indeed, the past year marks the close of a decade of construction of the rear-driving bicycle. Before proceeding to analyze in detail the constructional features for 1898, a bird’s eye view of the tendencies over the whole field will not be amiss.

REAR-DRIVER—1893.

The most striking characteristic tendency is the effort to introduce chainless rear driving, not altogether, however, by the bevel-gear. A careful census of the makers shows that some thirty prominent makers had perfected plans to place a chainless cycle of some sort on the market in 1898. Thus the season offers debatable ground between the advocates of the chainless and the chain-driven cycle. During 1898 is being fought the battle for supremacy between them, the chain-driven cycle being ably reinforced by its great and coming ally the gear-case, and the bevel-gear and other forms of chainless construction coming away from the realm of theory and the special pleas of the makers’ catalogues, and in the hands of the riding public will be put through that great crucible of public test, use on the road, under load, and under all sorts of conditions. The introduction of the chainless method of propulsion has, however, not radically changed the prevailing popular type of frame construction, and therefore the general tendency of construction, except the methods of propulsion, may be here surveyed as a whole.

DROP OF THE CRANK BRACKET.

Table of Contents

One of the most prominent tendencies of the season is the dropping of the crank-hanger bracket to a point from 2 inches to 4 inches below a line drawn through the centre of the wheel axles, the average drop on road wheels being 2½ inches, on light road wheels 2¾ inches, and on road-racing and track wheels, from these to the extreme limit. This lowering of the crank-hanger bracket has also necessarily brought with it a shortening of the steering head, in order to maintain the top tube horizontal or parallel with the ground. Lengths of head run from 4 to 8 inches, a fair average in length being about 6 inches, a change indeed from the long-head fad of a few years ago, under which heads have reached a length of over 13½ inches. Just what effect the shortening of the head will have on the steering remains to be found out by actual use, the makers who have used long heads having always claimed ease of steering for them.

Another point to be borne in mind in noting this tendency toward short heads, is that their use will necessitate the use of longer and therefore weaker handlebar stems, for those who use a medium or upturned bar, as well as long seat posts, more withdrawn from the frame. Of course, the scorcher with his drop bar will like the short head, and therefore its popularity may be wholly confined to this class of riders.

The most peculiar feature in connection with this drop of the frame is the very marked tendency toward the use of longer cranks and higher gears. In former years the average length of crank was 6½ inches for a man’s roadster, and 5½ to 6 inches for a lady’s wheel. A notable departure in this crank length this season is that three or four of the largest makers are equipping their ladies’ wheels with 6½ inch cranks, and men’s wheels with 7 and 7½ inch cranks. While this may be commendable in a cycle for men’s use, having a high gear, such crank length is positively objectionable on a ladies’ cycle, for several reasons, one of the chief ones being the increased knee action.

HEIGHT AND SHAPE OF FRAME.

Table of Contents

The length of wheel base—that is, the extreme measurement between the points where the two wheels rest on the ground—is not noticeably changed, the average being still about 43½ inches; this measurement has a close but not a quite fixed relation to the shape and angles of the frame. The rake or backward inclination of the diagonal stay is in most cases somewhat lessened, not now being in complete harmony with the rake of the front forks and head. This may be considered a change in the preferred direction, the forward position of the rider, nearly over
