Bicycle Tire Design
A bike, also known as a cycle or pedal cycle, is typically a motor-driven or pedal-operated, single-wheeled, human-powered machine, with at least two wheels attached directly to a rigid frame. A cyclist, commonly known as a biker, is also known as a bicycle rider, or biker. Bicyclists are typically involved in any type of street biking, off road biking, hybrid and traditional commuting. The most common types of bicycles are fixed wheel and recumbent bikes.
The fixed wheel bike (also known as a touring bike) has a straight seat and the pedals are placed directly on the ground. When the pedals are moved by the pedals, the chain stays below the seat. Because of this, the pedals are often set up in a way that they are perpendicular to the ground, instead of on the flat top of the seat pole. On the other hand, the recumbent bike is similar to the fixed wheel bicycle, but the seat is curved so that the handlebars can be viewed.
Riders prefer the upright or freewheel bike, because they feel more comfortable, and it requires less physical effort. The freewheel bicycle starts beneath the seat of the rider, and the handle bars are at the front end of the seat. Usually the handlebars are parallel to the ground, but they can be turned to the side or back for various reasons. A freewheel bike can be ridden on level ground, in the snow, and in almost any terrain where a bicycle is normally preferred. Unlike the fixed wheel bicycles, a freewheel does not have a fixed stem or seat.
Riders who prefer a bicycle with two wheels over one, usually prefer a bicycle with a freewheel. This type of bike has the pedals sitting beneath the seat in a curved path that allows the rider to look down the handlebars. Sometimes this type of bike has a fatter, softer wheel on the back wheel. A disadvantage to this type of bicycle is that it can be difficult to ride in the rain unless you have a good deal of clearance behind you.
The two-wheeled bicycle, or velocipede, differs from the reload by having a straight line between the pedals and the wheel. It was invented by Richard C. Laramy in 1903. The velocipedes are different than the tricycles in that they have two independent wheels. The pedals move in a circular motion, similar to a bicycle when you coast, but the actual movement occurs in two directions. This allows the rider to gain momentum and apply force to the pedals, which, in turn, causes the wheel to flip over. The major advantage of these bicycles is that they allow the rider to gain speed, unlike tricycles.
A final bike frame design includes a freewheel. The freewheel is similar to the tricycle in that it also has a pedal that rotates in a circular motion. The difference is that the freewheel is designed specifically for a single speed bicycle. A disadvantage to using the freewheel is that it is more difficult to control, as the rider needs to watch the rim for the seal. Another advantage of the freewheel is that it allows for more speed and makes a faster bicycle.
The three main types of bicycle wheel design include the plain wheel (conventional), the link (two wheels connected), and the clip (a single, solid wheel with a cross over). The plain wheel has the same advantages as any other bicycle tire, including having a deep tread for deep mud holes and preventing sideways slippage. The link is similar to the freewheel and uses a small inner tube that links the tire and the crankshaft. The clip wheel has a narrow profile that allows it to fit into deep mud holes and it also has a deep tread but unlike the link wheel does not have a deep, wide tire tread.
The steerer tube on a bicycle is shaped differently than a bike’s tire, which allows it to compress more easily and provide a softer ride. In addition, it acts as a giant valve, catching the pressure from the back wheel and blowing it away from the inside of the bicycle. Due to this design, the steerer tube is often referred to as a “through valve,” as it regulates where pressure goes through the entire tube.
