There are many different types of bicycles, each with different functions, designs and material makeup. One way to categorize bicycles, including the less conventional bikes, is to do it with the focus on the rider, which means the sitting position is different for each type of bicycle; it follows naturally that the design would be very different as well.
For example, an upright bicycle (now more popularly known as a safety bicycle) is the most common type of bicycle for the casual rider that requires the rider to sit astride the saddle; they were called safety bicycles because they had replaced the penny-farthings, the vintage type of bicycles with a very high wheel, the top of which the rider had to sit on. It is one of the bicycle types that use a so-called diamond frame consisting of the head tube, the top tube, the down tube and the seat tube, connected to each other to form the conventional bicycle design.
Bikes with reforms in certain parts that differentiate from this popular form of bicycle include the crank forward bicycle, on which the rider has no need to dismount in order to put his or her feet on the ground. A small wheel bicycle is also similar to the upright bicycle except that it has smaller wheels. A step-through bicycle is basically the same as an upright bicycle except it has a frame over which the rider does can put his or her leg across with much more ease because the top tube, the bar crossing in the front, is either absent or positioned very low. It is designed for riders who have to get off their bicycles very frequently, like those that deliver mail or run errands, and the more aged riders.
The term upright bicycle came from the need to distinguish it from the recumbent bicycle, an altogether different type of bicycle on which the rider lies or lies or leans in a supine or a semi-supine position; the rider looks quite comfortable riding this type of bicycle, leaning on his or her back. The weight of the rider is distributed evenly over the whole frame of the bicycle, rather than just a small saddle like it is on a conventional bicycle. This makes it aerodynamically superior, which is the reason why the world record for a bicycle’s speed is held by the recumbent bike. Racing is banned using this type of bike., but you can get them for leisure, and even tricycles of this type as well. This type of bicycle doesn’t follow the diamond frame and instead has the handlebars located in the center, and the pedals and chainset located at the front. A prone bicycle is similar in that it makes the rider lean, but in a prone position as opposed to a recumbent position; the rider leans well forward.
