What is a dirt bike (MTB)? Structure and advantages – disadvantages of MTB . bikes

Mountain bikes are often used to ride on steep, rocky mountain roads or rugged roads. So how is the terrain bike designed and what types are included, please refer to the article below with Tnhelearning.edu.vn!

What is an MTB mountain bike?

MTB terrain bike stands for the phrase Mountain Bike , is designed with a heavier weight than other bikes because it is designed with a large, sturdy frame and large, spiked tires for easier grip. handlebars (handles) are designed straight.

Thanks to the sturdy design of the frame and wheels, this car can run on all terrains including rough and steep places. Mountain bikes are classified into many different types, which are used for many different purposes depending on the type of terrain and purpose.

If you are a enthusiast with mountain biking in challenging mountainous areas, this is the ideal choice for you. However, when using the steering wheel, it is necessary to have dexterity to control the vehicle safely.

Structure of the car

Car frame set

Most bicycle frames are made of hard, sturdy, high-strength materials such as steel, titanium, aluminum, etc. The frame of the bike is considered as the backbone of the bicycle because of its function. Its main is to link the remaining parts into a block.

The chassis of the car includes parts such as: frame, fork and seat post.

Powertrain

The bike’s powertrain is known as the main operating center of the bike, helping the bike to move smoothly, rhythmically and smoothly.

The powertrain consists of components such as:

• Pedal (pedal)

• Middle shaft thigh

• Car disc

• Chain

• Lips

Motion system

The movement system of the MTB bike consists of 2 front and rear wheels . The wheels will combine with the rhythmic drive system to help the bike move forward.

The wheel of an MTB mountain bike is made up of the following main parts:

• Shaft : Made of steel, through the ball bearings, the wheel will rotate around the shaft.
• Wheel : Made of steel, the connection between the wheel rims is through spokes.

• Spokes : Made of steel, the small bars link together to help evenly stretch the rims.
• Wheel rim : Usually made of aluminum alloy or steel, about 650mm in diameter.
• Tubes and tires : Made of synthetic rubber, the surface of the tire often has spikes or patterns to help increase grip for the bike and avoid slipping during cycling.

Set of topics

The MTB series of mountain bikes are often equipped with front and rear forks to adjust the cassette and disc. At this time, the powertrain can be adjusted to suit many difficult terrains such as steep mountains, rocks, … making cycling easier.

The structure of the bicycle starter includes the front and rear derailleur, the starter lever and the cable.

Drive system

The steering system of the MTB mountain bike makes it easy for the driver to control the bike at will. When you act on the steering wheel, the force will be transmitted to the collar and the front wheel.

The front fork is responsible for controlling the front wheel of the bike, so the direction of movement of the bike will depend on the front wheel. The steering system consists of a handlebar (handgrip) and a seal.

Brake system

The brake system, also known as a brake, allows the rider to adjust the appropriate speed or stop the bicycle when necessary, helping to ensure the safety of the cyclist during the movement.

Bicycle brake system includes brake lever, brake line and brake pad assembly.

Brakes are divided into two main types : disc brakes and rim brakes.

Brake type	Disc brake	Braking brake (Mechanical brake)
Structure	Consists of a metal disc or “rotor” attached to the wheel hub and actuated by a brake line or hydraulically. The brake disc can be rotated with the wheel fixed on the unit. The brake line will be attached to the frame or disc together with the pad, the braking mechanism is to force the rotating shafts of the wheel to brake.	Activated by a lever mounted in the handlebar position. The action of the brake works on the friction mechanism on the wheel rim to help reduce the speed well.
Advantage	Easy to replace, does not cause rims and is suitable for most vehicles.	Compact, low cost.
Defect	Fragile damage due to high heat build-up can boil water in hydraulics.	It is easy to cause the wheel to wear out due to the impact of friction when braking.

saddle

The saddle is a part for the cyclist to sit and control, the more comfortable the saddle, the more comfortable it feels, and a good experience when using the bike. The saddle consists of the following main parts:

• Saddle cover : Usually the manufacturer is made of synthetic materials such as leather to ensure smoothness for the user.

• Hard saddle : This is the part that makes up the shape of the saddle, often designed with a compact and rounded nose.
• Under the saddle frame : The connection between the saddle and the rest of the bike. Most saddles have this part and are constructed with 2 parallel lines. In addition, some models have 1, 3 or 4 parallel lines.
• Tightening unit: Connecting the saddle to the saddle height adjuster helps users have the right posture when cycling, ensuring that the saddle is kept tight, safe and fixed.
• Height Adjustment : Allows for proper height adjustment, which helps reduce vibration and shock transmitted to the frame during cycling, creating a comfortable feeling

Advantages and disadvantages of MTB . mountain bikes

Each type of bike will have its own advantages and disadvantages. In the following comparison table, let’s take a look at what advantages terrain bikes have and where are their limitations.

Advantage

Defect

The vehicle has high reliability and safety. The friction with the road surface is large, so it moves well on rough and steep roads. The tires are thick and solid, so there is less chance of punctures in the middle of the road. The handlebars are straight, so the operator can sit upright, reducing fatigue more than the bent position. Wheels have many large and small grooves to help increase friction with the road surface, running well on mountainous and rough terrain. The fork has a large width, certainly helping to absorb shock when going on bumpy terrain.

The speed is not high compared to other cars. Vehicle is heavy. Tires are big and heavy, so if you go on a flat road, it will take more effort. Vehicles not equipped with fenders easily cause mud to splash on people. This vehicle can only go 1 person, so if you want to carry more people, you must install an additional saddle.

MTB . mountain bike classification

Cross-Country mountain bike

The cross-country mountain bike is the most commonly used type of mountain bike. This type of vehicle is manufactured from lightweight materials (aluminum or carbon) that help the vehicle move quickly and suitable for those who like to go through rural areas with not too rough roads.

Cross-country mountain bikes include two smaller lines, Hard Tail and Full suspension.

• The Hard Tail is equipped with a shock absorber at the front, which is often used to travel on terrain with few obstacles and no slopes such as trails, dirt roads, gravel roads or grass.
• Full suspension car has up to 2 front and rear shock absorbers, so it can go to places with less flat terrain and rough roads.

Freeride Mountain Bike

Mountain bike has a heavy weight, so the moving speed is also somewhat slower than the cross-country mountain bike. The vehicle has a large tire design, durable wheels and stronger brakes to climb steep steps such as mountains or stairs.

Downhill Mountain Bike

This is a vehicle used to specialize in downhill or extremely bad roads thanks to its large and sturdy chassis design. Along with that, the downhill bike is equipped with 2 to 3 forks , so it has better shock absorption, making it easier for the rider to move on the road with large obstacles such as rocks or tree roots.

Some notes when using MTB . mountain bikes

Before riding a mountain bike in a place with many obstacles, you need to practice many times to get used to how to brake in different terrains. Using the brakes on rough roads is not simple when you need to stop and squeeze, but you need to be quick to think and handle situations appropriately.

When climbing uphill, you need to keep the speed and pedal evenly to avoid falling back. In addition, you should bend forward to reduce wind resistance, limit rising from the saddle to reduce the ground grip of the rear wheel.

When going downhill, you also need to keep your pedals parallel to the ground to avoid hitting obstacles like rocks. This will affect the safety during cycling.
