A bicycle is a two wheeled vehicle driven by the riders feet pushing on cranks or pedals. A common misconception is that the earliest form of bicycle was the dandy-horse, which was pushed along by the rider's feet. However, while both the dandy-horse and the later bicycle are both velocipedes, the dandy-horse is not propelled by cranks.
The first bicycle was introduced to England from France in 1868, and comprised two solid wheels of equal size fitted to a frame, much like a modern bicycle in appearance, with a saddle fitted in the centre and propelled by cranks attached to the front wheel. This vehicle provided such a bumpy ride to the rider that it became popularly known as 'the bone-shaker'. Later came the Penny-Farthing with pedals fixed to the large front wheel which was made large to achieve high speeds. Later still, around 1895, came the safety bicycle with pedals driving the rear wheel by way of a chain, and the rider sitting upon a saddle set back from the front wheel so as to reduce the chances of falling forwards over the handlebars, from this developed the Raleigh bicycle design of 1900 which forms the basis of the modern bicycle. In 1888 the two-person tandem bicycle was invented.
In 1906 it was reported that speeds of 50 mph were attained on a bicycle. Around the same time, slightly earlier, the motorised bicycle (motorcycle or motorbike) was invented.
A typical bicycle is comprised of several parts. The principal and essential being: the frame, front forks, wheels, pedals, saddle, handlebars, chain and brakes. The largest part of the bicycle is the frame, and these vary in design depending upon the specialised intention of the bicycle.
A frame for a BMX bicycle being small, heavily braced and made of aluminium. The frame for BMX xyxling needs to be strong so as to endure the stresses of the bumpy ride, and the saddle low as competitors never sit down during a competition and as such they need space to sprint and jump with ease.
Cross-Country cycle frames are generally made of aluminium and carbon-fibre so as to be light weight. They are relatively small frames to allow quick and easy mounting and dismounting off road, and strong to endure off-road bumpy conditions. The smaller frames are often compensated for by having a longer seat post to allow a normal height saddle position.
The cycle speedway bicycle frame is designed primarily for strength, and as such is typically made from steel or aluminium.
Road racing bicycle frames are designed to be light and stiff. Traditionally they ewre made of steel, but by the start of the 21st century carbon fibre was being used for the more expensive models as this offered the same stiffness at reduced weight. The design of the tubes also developed over time, tubes becoming of a larger diameter, but thinner walls, to allow the same stiffness with reduced weight.
Bicycles are fitted with various types of brake, the most popular being the calliper, cantilever, hydraulic or disc and the V brake. The most common form of brake found on leisure bicycles, is that form used also on road racing bicycles. The calliper brake. Calliper brakes are a very efficient means of rim braking and basically comprise two blocks of rubber or plastic which are squeezed onto the wheel rim when the brake lever is squeezed by the ride.
Cantilever brakes operate on the same principal as calliper brakes, but are of a slightly different design at the wheel end, offering increased clearance between the tyre and the brake pads and as such are frequently employed for cyclo-cross bicycles and mountain bikes.
The most efficient form of rim brake is the V brake. The V brake also offers the most clearance of any rim braking system, and is most often found on mountain bikes.
Hydraulic or disc brakes are the most efficient and powerful form of bicycle brake. They use the wheel hub to brake, rather than the rim. Disc brakes offer the most clearance, and as such are used on mountain bikes, but are also expensive to fit and maintain.
Bicycle wheels are generally of one of three types. The most common and traitional bicycle wheel is the spoked wheel, comprising a rim connected to the central bub by a series of thin metal rods known as spokes. Spoked wheels are light in weight. Less common than spoked wheels, but offering greater strength and durability at the expense of weight are mag wheels which comprise a rim attached to the hub by a few, thick solid plastic bars. Solid wheels, also known as disc wheels, are made from composite material or carbon fibre are very strong, stiff, aerodynamic and very expensive. They are rarely used except as rear wheels in time-trialing and track racing.

Grafting is an operation by which a bud or scion of an individual plant is inserted upon another individual, so as to become organically united with the stock on which it has been placed. Grafting can only take place between plants which have a certain affinity, individuals of the same species, genus, or order. The graft does not become identified with the stock to which it is united, but retains its own peculiarities of variety or species. The parts between which grafting is effected must be actively vegetating.
The advantages derived from grafting are the preservation of remarkable varieties, which could not be reproduced from seed; the more rapid multiplication of particular species, and the anticipation of the period of fructification, which may thus be advanced by several years. The principal methods of grafting are 1. By approach This process is intended to unite at one or more points two plants growing from separate roots. Plates of bark of equal size are removed, the wounds are kept together and protected from air. Stems, branches, or roots may be united in this way. 2. By scions - Under this head there are a variety of methods, such as whip, splice, cleft, saddle, crown grafting, etc.
In whip-grafting ot tongue-grafting the stock is cut obliquely across and a slit or very narrow angular incision is made in its centre downwards across the cut surface, a similar deep incision is made in the scion upwards, at a corresponding angle, and, a projecting tongue left, which being inserted in the incision in the stock, they are fastened closely together.
Splice-grafting is performed by cutting the ends of the scion and stock completely across in an oblique direction, in such a way that the sections are of the same shape, then laying the oblique surfaces together so that the one exactly fits the other, and securing them by tying or otherwise.
In cleft-grafting, the stock is cleft down, and the graft, cut in the shape of a wedge at its lower end, is inserted into the cleft; while, in saddle-grafting, the end of the stock is cut into the form of a wedge, and the base of the scion, slit up or cleft for the purpose, is affixed.
Crown-grafting or rind-grafting is performed by cutting the lower end of the scion in a sloping direction, while the head of the stock is cut over horizontally and a slit is made through the inner bark. A piece of wood, bone, ivory, or other such substance, resembling the thinned end of the scion, is inserted in the top of the slit between the alburnum and inner bark and pushed down in order to raise the bark, so that the thin end of the scion may be introduced without being bruised. The edges of the bark on each side are then brought close to the scion, and the whole is bound with matting and a lump of clay put round it.
3. By buds - This consists in transferring to another stock a plate of bark, to which one or more buds adhere. Bud-grafting is the most commonly practised, especially for multiplying fruit-trees and roses, owing to the facility with which it may be performed.

Pony girls is a form of adult sexual entertainment role play or fantasy in which women pretend to be a horse or pony (a pet for their master) while their sexual partner pretends to be the horse or pony's master (known as the top). Pony girls are, therefore, a branch of the bondage and domination, the animal training group of sex games and frequently the sex play involves sado-masochism also.
The pony girl participant (also known as the bottom) takes her role play very seriously. Prancing on her legs, with her arms held close to her sides, the elbows extended forwards, and the wrists allowed to droop, in a fashion not dissimilar to a pony raised on its hind legs and prancing.
Elaborate attire is often employed to enhance the effect. A plume in imitation of the type of plume that is sometimes seen adorning a pony's head may be worn upon the head. Other participants prefer a headdress which includes imitation horse's ears. A fake horse's tail is worn behind, either held by being tucked into a belt or strap around the waist, or sometimes fitted with an anal plug for insertion into the pony girl's anus.
Harness straps, similar to those one might find adorning a real pony or horse are worn around the body, as is a bridle comprising a headstall, bit inserted in the mouth and reins. Sometimes blinkers are also worn, depending upon the preference of the participants. These components provide a sense of bondage and heighten the sexual sensations immensely for both the pony girl and her master. Some pony girls also wear boots in imitation of horse's hooves upon their feet.
Some pony girl games involve humiliation, with the pony girl being the master's pet, or pony slave, being forcibly trained and abused by the master from which both participants derive great sexual excitement.
Pony girl sex games properly require to be played in the open air. The very nature of a horse demands a field or largish area of open space at least in which to conduct the fantasy. A typical session may include training, in which the pony girl properly attired is attached to a long lead, just like a pony when it is being trained, and trots around the master at some little distance in response to suitable commands such as trot and walk, etc.
Following training, a pony girl may be hitched to a small trap which she is then required to pull while the master sits in the trap and encourages the pony with the use of a whip, again, just like with a real pony. Other participants may attach a horse's saddle to the pony girl, who having adopted a posture on all-fours is then ridden by the master like he would ride a real pony. A variation of this is when the pony is a man and the master is a woman - a dominatrix. In this instance, sometimes the dominatrix, attired perhaps in full riding regalia, will ride upon the pony's shoulders with her feet resting in stirrups suspended by suitable harnesses from the man's shoulders or attached to his wrists which are in turn attached to a harness or belt passing around his waist.
By the very nature of the pony girl fantasy sex game, it is usual for the participants, and the pony in particular, to be in some degree of undress. Often the pony girl will be naked except for the leather straps - usually of black leather studded with silver metal coloured discs, rings and chains - and plumes, or at least with her breasts exposed. If the pony girl has pierced nipples, these nipple rings are frequently attached by chains to the headstall, providing her with further stimulation of the nipples during the fantasy. The feet are sometimes bare, but most often adorned with high-heeled platform shoes or custom ankle boots adorned to represent a horse's hooves. Rarely the pony girl will also wear imitation horses hooves gloves. But most frequently the hands are left natural.
Other participants may dress the pony girl in tight latex, or leather wear. In order to enhance the fantasy costume and attire are very important. The fantasy would be lacking realism if the pony girl wore simply street clothes and had a simple rope for reins. Instead, appropriate bondage wear is utilised to enhance the sexuality of the game. The master also is usually dressed up. Riding wear, such as jodhpurs, a riding hat and boots being popular, or else more common bondage master wear, such as tight latex or leather with high stiletto heeled boots enhancing the degree of menace and authority of the master.
During training the pony girl may choose the level of obedience she wishes to portray. A disobedient pony may be whipped, or shouted at. A well behaved pony girl may be fed a sugar cube as a reward, taking the sugar from the master's hand with just her mouth, just as one might reward a real pony. Appropriate pony-like noises are expressed by the pony girl, such as snorting like a pony which further add realism to the fantasy.
The pony girl fantasy may be played by two or more participants, and is often played by three with a single master and two ponies. Pony boys are a variation in which a man or men play the role of the submissive pony, and the master may be another man or more often a dominant female partner - a dominatrix.

A saddle is a contrivance of wood and leather securely bound with a girth or leather straps to the back of a horse, to serve as a seat for the rider or to carry the weight of the shafts of a vehicle. Other forms of saddle are used for other animals, such as camels and oxen. The seat of a bicycle and motorcycle is also called a saddle.

The Airedale terrier breed of large terrier, about 60 centimetres tall, with a wiry red-brown coat and black saddle patch. It originated about 1850 in Yorkshire, England, as a cross between the Otterhound and Irish and Welsh terriers and was named after the River Aire, although the breed was known by various names until the name Airedale Terrier was established at the 1879 Airedale Agricultural Show.

The ass or donkey (Equus asinus) is a species of the horse genus, supposed by Darwin to have sprung from the wild variety {Asinus toeniopus) found in Abyssinia; by some writers to be a descendant of the onager or wild ass, inhabiting the mountainous deserts of Tartary, etc; and by others to have descended from the kiang or djiggetai (Asinus hemionus) of southwestern Asia. Both in colour and size the ass is exceedingly variable, ranging from dark grey and reddish brown to white, and from the size of a Newfoundland dog in North India to that of a good-sized horse. In the south-western countries of Asia and in Egypt, in some districts of Southern Europe, as in Spain, and in Kentucky and Peru, great attention has been paid to selection and interbreeding, with a result no less remarkable than in the case of the horse. Thus in Syria there appear to be four distinct breeds: a light and graceful animal used by ladies, an Arab breed reserved for the saddle, an ass of heavier build in use for ploughing and draft purposes, and the large Damascus breed. The efforts made to raise the deteriorated British breed during the 19th century were only partially successful.
The male ass is mature at two years of age, the female still earlier. The she-ass carries her young for eleven months. The teeth of the young ass follow the same order of appearance and renewal as those of the horse. The life of the ass does not usually exceed thirty years. It is in general much healthier than the horse, and is maintained in this condition by a smaller quantity and coarser quality of food; it is superior to the horse in its ability to carry heavy burdens over the most precipitous roads, and is in no respect its inferior in intelligence, despite the reputation for stupidity which it has borne from very ancient times. The ass has a keen sense of humour and mischief, and domestic ass delight in throwing riders into rivers and thorn bushes, and also tripping over the unwary.
The skin is used as parchment to cover drums, etc, and in the East is made into shagreen. The hybrid offspring of the horse and the female ass is the hinny, that of the ass and the mare is the mule; but the latter is by far the larger and more useful animal. Asses' milk, long celebrated for its sanative qualities, more closely resembles that of a woman than any other. It is very similar in taste, and throws up an equally fluid cream, which is not convertible into butter.
