Top 10 Best Explanatory Essays on Bicycles

Hello, I am the bicycle that has been a close companion to many people. Although we are so familiar, many may not know everything about me. Let's take a journey to discover more.

If someone were to ask about my origins, I would proudly say, 'Bicycles have been around for nearly two centuries.' Historical records reveal that as early as ancient Egypt, there was evidence of a two-wheeled vehicle powered by human feet. However, it wasn’t until 1817 that bicycles started to be widely used.

Although I may appear simple, I actually have many intricate parts. My structure, and that of my fellow bicycles, includes a drivetrain system, a control system, and a transportation system.

The drivetrain consists of the frame, pedals, bottom bracket, bearings, chain, sprocket, two axles, and front and rear wheels. When riding, a person sits on my saddle, holds the handlebars, and pedals, making the axle move, which in turn moves the chain and rear wheel, propelling me forward.

The sprocket, which has a larger diameter than the freewheel, contains more than twice the number of teeth. When the sprocket rotates once, the freewheel turns more than twice, which causes the wheel to move. With a diameter of 650mm or 700mm, the wheel turns much farther with each rotation, thus speeding me up.

The control system includes the handlebars with grips that rotate left or right easily, aided by the stem and bearings, allowing the rider to steer the front wheel as desired. The handlebars serve as both a steering device and a balance stabilizer. The braking system, consisting of the brake lever, cable, and brake caliper, slows or stops the bicycle by pressing brake pads against the rims, reducing the speed or halting altogether when needed. The brakes allow riders to control their speed.

The transportation system includes the saddle, luggage carrier, or basket. The saddle is mounted on the frame for the rider's seat. The carrier, attached behind the saddle and resting on the rear wheel axle, can carry heavy loads. The basket is typically attached to the front of the bicycle, supported by the front wheel axle.

In addition to these primary components, I also have mudguards over the front and rear wheels (also known as fenders), a chain guard above the chain, a dynamo-powered light on the front fork, a rear signal light, and a bell for signaling when necessary.

I take pride in being an efficient form of transport for short distances, such as within villages or small towns. I don’t pollute the environment as I operate using human energy. Moreover, cycling helps improve physical fitness, strengthens the cardiovascular system, firms muscles, and trims the waistline. Cycling for at least 20 minutes a day can increase life expectancy, reduce stress, and enhance bone health and coordination skills.

Not only that, but I am a dear companion to those who have experienced school life. For students, even after many years away from school, I am sure the memories of me remain vivid in their hearts. Those hot summer afternoons, the baskets full of red flowers, or the summers of an 18-year-old boy, all leave an indelible mark.

Remember the days of school, when I carried both joys and sorrows of a youthful, innocent time. After graduation, 'everyone understood, except for one person...' During the skipped lessons, I accompanied students as they bonded over mischievous games that made the 'wild childhood' unforgettable. In rain or shine, I was always there, with them.

As society evolves and technology advances, I believe modern transportation may become more convenient for everyone. But I will always take pride in being a companion who understands and shares. I will continue to accompany people through life’s rhythms, guiding them toward success.

In today’s rapidly developing society, where technology continues to advance, there are now numerous transportation options available to us, such as motorcycles, bicycles, cars, and even airplanes. However, for many people today, owning a bicycle remains essential for getting around. Though the bicycle has existed for a long time, it continues to hold significant value for everyone.

So, where did the bicycle originate? While many people are familiar with bicycles, few know the true origin. The bicycle was invented in Europe and introduced to our country in the early 20th century. It is a human-powered vehicle with a simple design, easy to control, and very convenient for transportation.

It has been a constant companion throughout history, especially during wartime. However, in large cities today, bicycles have become less common, overshadowed by modern technology and newer innovations. The bicycle is a two-wheeled mode of transport and a widely-used sports device. Most bicycles move by the rider’s pedaling, and balance is maintained by the law of conservation of angular momentum.

The bicycle is considered an environmentally friendly mode of transport. It is widely used in many low-income countries as the primary mode of transportation. In many Western countries, bicycles are less commonly used for daily commuting but are popular for recreation, sports, and outdoor activities.

Riding bicycles is encouraged in many countries because of its environmental benefits. It is also ideal for navigating narrow streets where other vehicles cannot go, such as in old city districts with historic architecture.

The structure of a bicycle includes control and transport systems. The bike consists of the frame, pedals, bottom bracket, chain, sprockets, axles, bearings, and front and rear wheels. When riding, the rider sits on the saddle, holds the handlebars, and pedals, causing the axle to turn. The motion of the sprocket drives the chain, which turns the freewheel and rear wheel, propelling the bike forward.

The sprocket has a larger diameter than the freewheel and more than twice the number of teeth. When the sprocket turns one full rotation, the freewheel rotates more than twice. With a wheel diameter typically between 650mm and 750mm, it covers much more distance in one rotation. This makes the bike accelerate as the freewheel spins faster.

The control system includes the handlebars, which have two grips that can rotate easily to steer the front wheel. The handlebars serve as both the steering mechanism and a means for the rider to maintain balance. The braking system consists of brake levers, cables, and calipers, which press the brake pads against the wheels, creating friction to slow down or stop the bike as needed.

Thanks to the braking system, the rider can adjust their speed or stop whenever necessary. The transport system includes the saddle, cargo carrier, and basket. The saddle is mounted on the frame and can be adjusted to suit the rider’s height. The rear carrier, located behind the saddle, can hold heavy loads. The front basket is mounted on the front axle for carrying items.

In major cities, the overwhelming number of motorcycles causes traffic congestion and environmental pollution. In the future, as public transportation expands, bicycles will continue to be an essential personal transport option—clean, convenient, and eco-friendly.

At one time, bicycles were the primary mode of transportation for many people in Vietnam. A bicycle is a simple vehicle powered by human effort.

The bicycle is composed of several key parts, primarily the drivetrain, control system, and transport system. The drivetrain includes the frame, pedals, bottom bracket, bearings, chain, sprockets, freewheel, axles, and front and rear wheels. The rider sits on the bike and pedals, causing the axle to rotate. This turns the sprocket, which drives the chain, making the freewheel and rear wheel rotate, propelling the bike forward.

The sprocket has a larger diameter than the freewheel and more than double the number of teeth. When the sprocket turns once, the freewheel turns more than twice. The freewheel’s rotation moves the wheels. With a wheel diameter of 650mm or 700mm, 10 times larger than the freewheel’s diameter, a single rotation of the freewheel propels the bike a significant distance. Faster freewheel rotation results in faster bike speed.

Initially, bike wheels were made of wood, making for a very bumpy ride. Today, wheels are made from rubber with tires and inner tubes, which, when properly inflated, provide a much smoother ride.

The control system consists of handlebars with two grips that rotate to steer the front wheel. The handlebars serve both as the steering mechanism and as supports to keep the rider balanced. Brakes are located at the ends of the handlebars, controlling the speed and allowing the rider to slow down when traveling at high speeds.

The brake system includes levers and cables that apply pressure to the brake pads, creating friction against the wheel rims. This slows down the bike or brings it to a stop when necessary. The braking system gives the rider full control over when to stop or slow down.

The transport system includes the saddle, rear carrier, and baskets. The saddle is mounted on the frame, providing a seat for the rider. A rear carrier attached to the back of the saddle is supported by the rear axle and can carry heavy loads. A front cargo holder may also be mounted on the front axle for additional storage.

In addition to these main components, bicycles are equipped with a chain guard, fenders on both the front and rear wheels, a headlamp powered by a dynamo mounted on the front fork, a rear signal light, and sometimes a bell near the handlebars. Bicycles are convenient for short trips, especially in villages and small cities. They are eco-friendly and contribute to physical activity as a form of exercise.

Currently, with the excessive number of motorcycles on the roads, bicycles have been overshadowed, causing traffic congestion and environmental pollution. However, as public transportation expands in the future, the bicycle will continue to be an essential personal transportation mode—clean and convenient.

The bicycle is a familiar, user-friendly mode of transport with a simple structure and easy control, ideal for short-distance travel.

A bicycle consists of a drivetrain, control system, and transport system. The drivetrain includes the frame, pedals, bottom bracket, chain, sprockets, and freewheel. When riding, the rider sits on the saddle, grips the handlebars, and pedals, which drives the axle. This turns the sprockets, which move the chain, rotating the freewheel and rear wheel, propelling the bike forward.

The sprocket has a larger diameter and more teeth than the freewheel, with its teeth more than double those of the freewheel. When the sprocket turns one complete revolution, the freewheel turns more than twice, causing the wheels to rotate accordingly.

The control system includes handlebars with grips that rotate easily. The handlebars serve as both steering and balancing aids. The braking system comprises levers and cables that apply pressure to the brake pads, generating friction with the rims. This slows the bike down or halts it when needed, allowing riders to adjust their speed at will.

The transport system consists of the saddle, cargo carrier, and baskets. The saddle, mounted on the frame, serves as the rider’s seat, while a front basket, mounted on the front axle, holds goods. Additional parts such as mudguards on the front and rear wheels, a chain guard, and a bell are also included.

Bicycles are an efficient means of transport for short trips, ranging from a few to several dozen kilometers, such as in villages or small cities. Since they are human-powered, bicycles do not contribute to environmental pollution. Cycling also offers physical exercise, enhancing overall health.

During the Vietnam War, bicycles were crucial in transporting food and supplies along the Ho Chi Minh Trail, supporting the efforts to expel the American invaders and reunite the country.

In the modern world, bicycles are gradually being replaced by other transportation methods, but they are expected to make a comeback in the future to reduce pollution. Bicycles remain a safe, convenient, and easy-to-use transportation option.

In today's context, as the environment faces numerous challenges and transportation contributes significantly to air pollution, the use of bicycles has become increasingly popular and highly valued.

Furthermore, cycling provides convenience and flexibility, without being tied to the operating hours of public transport systems.

In conclusion, bicycles are not just an eco-friendly means of transportation but also offer numerous benefits for health and personal finances. Encouraging bicycle use is not only a way to reduce environmental pollution but also a means to improve health and enhance the overall quality of life.

In today's daily life, we encounter a variety of transportation methods that are convenient, easy to use, and meet human travel needs, such as cars, motorcycles, airplanes, and trains. However, I still have a special fondness for a vehicle that has been around for a long time, is compact, and serves the purpose of transportation well – the bicycle. This simple yet essential device is a familiar companion in our lives.

The bicycle first appeared in Europe and was introduced to Vietnam in the 20th century. It is a human-powered vehicle with a simple design and easy maneuverability, making it an ideal mode of transportation. In 1790, the first bicycle appeared, initially known as the Célérifère, invented by Count Sivrac. It was a wooden contraption without a steering wheel, and turning required shaking the front part of the bike.

In 1849, a German mechanic named Heinrich Fischer, or perhaps the Michaux brothers, invented the pedal, located at the front wheel. This innovation made the front wheel larger than the rear wheel, increasing the distance traveled with each pedal stroke. This improvement led to the term “bicycle” being used for the first time. While bicycles are being replaced by motorcycles in many urban areas, they are still a common mode of transportation in rural regions.

A bicycle consists of several components: the drivetrain, the control system, and the transport system. The drivetrain includes the frame, pedals, bottom bracket, ball bearings, chain, gearset, axle, and the two wheels. When riding, the rider sits on the seat, grips the handlebars, and pedals to rotate the axle, which drives the chain, turns the gears, and propels the rear wheel forward.

The control system includes handlebars with grips that can easily rotate left or right, thanks to the ball bearings in the fork. These handlebars not only help steer the bike but also maintain balance. The braking system uses brake handles that press against the rims, creating friction to slow or stop the bike as needed. This allows the rider to adjust speed and stop whenever necessary.

The transport system includes the seat, the cargo rack, or the basket. The seat is mounted on the bike frame and provides a place for the rider to sit. The cargo rack, attached to the rear, can carry heavy loads, while the front basket is used to hold smaller items.

Besides these main parts, the bicycle also has mudguards on the front and rear wheels, chain guards, a dynamo-powered light at the front fork, a rear signal light, and a bell near the handlebars to signal others when needed.

The bicycle is an excellent mode of transportation for short trips, whether in a village or a small city. Since it’s powered by human energy, it doesn’t pollute the environment. It also provides an effective way to exercise and stay active. In both the French and American wars, bicycles played an important role in transporting supplies and weapons along the Ho Chi Minh Trail, helping to free the country from foreign invaders and reunite the nation.

In urban areas, the increasing number of motorcycles has led to traffic congestion and environmental pollution. However, in the future, as public transportation becomes more widespread, bicycles will continue to be a valuable personal transportation option—clean, efficient, and convenient. Over time, bicycles have evolved, with wooden wheels replaced by inflatable tires that offer a smoother ride and faster speeds. Today, there are various types of bicycles, such as mini bikes, men's bikes, mountain bikes, and racing bikes, each catering to different needs and preferences.

Bicycles remain one of the most common and essential vehicles in everyday life, especially for short-distance travel. Although more modern vehicles have emerged, bicycles offer numerous benefits, not just for the environment, but also for personal health. For this reason, bicycles remain a popular choice for many people around the world.

As society progresses, so does the development of various transportation methods. We have motorcycles, cars, airplanes, trains, and more. However, the bicycle remains the most beloved and familiar mode of transport for many generations. The bicycle has accompanied many people through their childhoods and continues to be a staple on streets today, a vehicle that remains indispensable.

The bicycle first appeared in Paris, invented by a German baron. The early version was made of wood and underwent many modifications before becoming as practical as the bicycles we use today. There are various types of bicycles, including regular bikes, racing bikes, and mountain bikes, each designed for specific purposes.

The bicycle didn’t emerge as the earliest mode of transport, but it paved the way for the invention of motorcycles and cars. A bicycle includes handlebars that allow us to steer the vehicle, and brakes that help us stop while riding. The front handlebars typically feature a basket, which makes it convenient for carrying items, a feature commonly used by women when they go shopping to reduce the load of carrying heavy bags.

To ensure comfort, bicycles are equipped with a seat for one rider. Additionally, the rear frame has a cargo rack to carry larger loads or even passengers. This rack is usually made of metal, and though it may be somewhat uncomfortable to sit on, people often add a cushion for more comfort.

The bicycle consists of two wheels attached to a frame, with a front and rear wheel. In the earliest versions, the front wheel was much larger than the rear, and pedals, or footrests, were attached to the front wheel. After many improvements, modern bicycles now feature two wheels of equal size, with pedals positioned in the middle, connected to a chainset.

When we apply force with our legs, the pedals rotate, which in turn moves the chain and propels the wheels forward, making the bicycle move. The most crucial part of the bicycle is the frame, which is now made from durable metals, unlike the wooden frames of the past that were prone to rotting.

With the help of computers, the frame is now designed with precision, and the introduction of rust-resistant materials has made the bike more durable over time. Additionally, specialized bicycles for various terrains have been developed, making biking more versatile and convenient.

Riding on city streets is never easy, and designers have added several components to ensure safe travel. Bicycles are equipped with front and rear lights to signal other vehicles during nighttime rides. They also feature a bell to alert others when changing direction. On rainy days, mudguards are installed to minimize the amount of mud and water splashing onto the rider and the bike.

Unlike motorcycles and cars, bicycles do not rely on engines, which means that long trips may require more effort. However, bicycles offer many benefits. They are lightweight, portable, and easy to carry, unlike the bulky motorcycles and cars. Since they don’t rely on fuel, you don’t need to worry about engine failure in the rain. Most importantly, bicycles are an environmentally friendly mode of transport.

Because they only use human energy, bicycles do not consume resources like gasoline or oil, which are increasingly scarce. Bicycles also produce no emissions while in use. Additionally, their lightweight design means they don’t cause road damage or require much effort to maneuver.

To ensure a long lifespan, bike owners should regularly clean and check their bikes for any issues, like rusting chains, and apply lubricant when necessary. It’s also important to equip the bike with a reliable braking system for safety, especially when riding on steep or winding roads.

“Waiting at the familiar street corner, just me

Only me, with longing, even though we are together

Riding bikes through the streets after school”

The bicycle has been an inseparable part of many Vietnamese students' lives, carrying their school uniforms to school every day, taking them closer to knowledge. It has journeyed through history alongside the nation, with bicycles providing support for soldiers on the frontlines during wars. As it continues to play an essential role in daily life, the bicycle remains an iconic image of Vietnam’s culture and an unforgettable part of many generations' childhoods.

As technology continues to advance, many forms of transportation have been created to make human travel more efficient and convenient. Among these, the bicycle is the most accessible and widely used by people of all ages. Originating from Europe, bicycles have undergone numerous improvements, eventually becoming the reliable mode of transport we use today. Bicycles first arrived in Vietnam around the early 20th century and have since become an indispensable part of daily life.

The bicycle is made up of three main systems: the control system, the motion system, and the carrying system. The control system consists of handlebars and brakes. The handlebars are uniquely shaped like the number 3 and serve as both the steering mechanism and a stabilizer, helping the rider maintain balance. Thanks to the handlebars, we can steer the bicycle left or right as we wish.

The bicycle's brake system ensures the bike slows down or comes to a complete stop when necessary. The motion system includes the frame, pedals, crankset, freewheel, bearings, gears, and wheels. The frame, often made from metal, acts like the backbone of the bicycle. As the rider sits on the saddle, their feet engage with the pedals, applying force that turns the pedals and moves the wheels. The gear ring, larger than the freewheel, has twice as many teeth as the freewheel.

The carrying system includes the saddle, front basket, and rear rack. The saddle provides a seat for the rider and can be adjusted for different heights. The basket and rear rack can carry loads ranging from 3 to 10 kg. Additionally, there are several auxiliary components like mudguards, a bell, and lights, which are particularly useful when cycling at night.

Bicycles are incredibly useful in our daily lives. They are ideal for short distances, narrow streets, and places with many small alleys. Bicycles are also perfect for outdoor activities and exercising. Experts have pointed out numerous benefits of regular cycling.

Cycling frequently helps build muscles, burn calories, and keep joints healthy, improving cardiovascular function. Aside from physical fitness, cycling also benefits mental health. It’s an enjoyable, free activity that helps reduce stress and improves overall well-being, making individuals feel happier and more connected to others.

In today’s world, with environmental pollution becoming a pressing global issue, bicycles hold even more significance as they contribute to protecting the environment by not emitting CO2, which contributes to global warming. Many developed nations encourage citizens to cycle to maintain cleaner air.

During wartime, bicycles played a crucial role in transporting supplies such as food, medicine, weapons, and ammunition to the frontlines. These bicycles, along with their riders, traversed the vast landscapes of the country, from plains to mountains, and through dense forests and difficult terrain.

In response to modern needs, various specialized bicycles have been created, including four-wheeled bikes for children, everyday bikes, sports bikes, and mountain bikes. To ensure that a bicycle lasts longer, it should be cleaned regularly, and care should be taken to avoid rough roads with potholes.

Even as advanced vehicles continue to emerge in the future, bicycles will remain a trusted companion for people on their journeys. Despite their simplicity, bicycles will always hold an irreplaceable role in our lives.
