However, simple bicycle maintenance from home is also needed so that the performance of Rider's flagship bike is maintained. Riders can try to learn how to properly care for their bikes at home. Here we have prepared some tips that Rider can use, take a look! To keep the bike in perfect condition, there are a few things that Riders should pay attention to and try to do. The following are easy and practical tips that Riders can use as guidelines for maintaining bicycles. By doing so, Rider can have a bicycle that is long-lived and suitable for long-term use.

 1. Keep the Bike Clean

As a tool filled with various kinds of rotating components, bicycles really need to be kept clean. At least on the rotating component. By keeping it clean, the rotation of the components will run smoothly. Riders can enjoy cycling without any distractions. To keep the bike clean, Rider can wash it regularly. Make sure Rider uses running water when washing the bike. Don't forget to adjust the pressure. We recommend Rider use normal or regular pressure when washing the bike. Water with high pressure will risk damaging bicycle components, especially those filled with lubricating fluid, such as chains. When finished washing, make sure Rider wipes all parts of the bike with a soft cloth. Do not allow any water to collect.

2. Apply Lubricants

If so, don't forget to apply lubricant to the bicycle chain, so that the chain does not rust quickly and remains safe to use after washing it clean. The provision of this lubricant helps maintain the performance of the bicycle so that it remains safe and comfortable to use. And can prevent wear and rust on the bicycle chain. That way the bicycle chain will work optimally. When lubricating, make sure it has enough capacity as needed because it can trap dust and make the bike dirty quickly. In addition to the chain, Rider also needs to lubricate other components on the bike. Such as headsets, seat clamps, RD pulleys, bicycle hinges (if they are folding bikes), and many others.

3. Do a Wind Pressure Check

Tires are one of the most important components in a bicycle. When the tires are not in a stable condition, it is certain that the Rider will feel uncomfortable riding a bicycle. Checking the air pressure in the tires is an important tip that Riders must do. By checking the air pressure, Rider has taken care of the tires to have a long life. If the Rider uses a race bike, the recommended tire pressure is around 80 to 130 psi. Mountain bikes required pressure of about 25 to 35 psi. For other types of bicycles, it is certain that the air pressure in different tires is required because each type of bicycle uses different tires. The best solution for riders is to provide a pump at home according to their needs. For the pump choice, Rider can use a mini pump or a high-pressure pump. These tips are to keep bicycle tires in top condition when they are used.

4. Fix Any Minor Damage

The next tip that Riders can do to take care of their bike is to repair the bike when it breaks. Ball bearings or often also called bearings are components that are located on the moving parts of a bicycle. For example, in the bottom bracket, pedals, hubset, headset, rear shock pivot, and many others. Riders can fix it from home. For example, by tightening the bolt on the pedal, using a screwdriver (regular) for manual bicycles. Another example of minor damage, on the Seatpost which is often loose. So that makes the saddle position often fluctuate. Riders can also solve this problem at home using tools, such as special levers or locks. To make it easier for Rider to repair minor damage to the bike above. The rider can provide folding tools, and serves to store bicycle repair equipment that is easy to carry around. Folding tools contain special levers or keys for bicycle repair. Starting from 2 mm hex keys, 2.5 mm hex keys, and other sizes.

5. Perform bicycle service regularly

When the bicycle starts to make an annoying sound, it can be ascertained that there is damage to the bicycle component of the ball bearing. Ball bearings that start to wear and dry greatly hinder the movement of the bicycle. Usually, this can happen because of water or degreaser that enters the bearing housing. It's time for Rider to immediately do service to the workshop. Of course, regular bicycle checks must be carried out by Rider, before the bicycle is damaged as above. If Rider feels confused and doesn't know how to fix a damaged bicycle, Rider can take it to a bicycle service center. Riders can perform routine bicycle services with the help of a trusted Aquickrelease mechanic. Aquickrelease provides the best bicycle service services with various advantages. It is guaranteed that Rider will feel perfect satisfaction and be able to use his favorite bike with the best performance and of course for a long time. In caring for a bicycle in general, it can be given the same treatment. However, Riders should know that there are some slightly different rules for servicing bicycles. And it depends on the type of bike. Riders can find out how to properly care for different types of bikes to keep them durable.

Understand The Functions and Parts of Mountain Bike

Mountain biking or MTB (mountain biking) was first introduced in 1970. They were considered unpopular, but over time, 80% of Americans preferred this type of bicycle. So far, bike makers have begun to compete for the best mountain bikes, including well-known brands such as United, Polygon and Element. When planning your purchase of a mountain bike, first determine the terrain in which it will be used. Also pay attention to the frame material, braking system, tire diameter and bike weight. Ten high quality mountain bikes are waiting for you on the recommendation list, but first you need to think about the selection points to consider. Happy reading!

Mountain Bike Selection (MTB / Mountain Bike)

Here are some tips for choosing an MTB that you can use as a guide before you buy your dream mountain bike. Check the following points! Check the materials used for the frame The frame is where other bicycle components are mounted, so the frame is the most important part of the bike. There are many variations of bicycle frame materials on the market.

• High-strength steel.

High-strength steel frames, also known as high-strength steel, are often used in the low to medium-priced range. This is because it is heavy because it is steel, but the material is very durable and reasonably priced.

• Chromoly.

Manufactured from steel mixed with chromium and molybdenum. The quality is slightly better than lightweight high-strength steel. This frame is suitable for crossing extreme distances.

• Aluminum alloy.

It is the most popular material in almost all price ranges. The advantages of alloys are that they are much lighter than steel and have higher corrosion resistance and strength. However, if the frame is dented, it will be difficult to repair.

• Carbon fiber (carbon fiber).

Due to its light weight, it is very comfortable to use. The easily malleable material gives most carbon fiber frames a unique and cool design. The material does not rust either. However, the price is relatively high and the heat resistance is low, and it is difficult to repair if it is damaged.

• Titanium.

For those who are preparing more budget for mountain biking, a titanium frame is the best choice. This frame is extremely stiff, stiff, lightweight and durable. This material is also commonly used by professional bikers as the mainstay of competition. The product recommendations below include a description of the bike frame materials to facilitate the selection process.

Get to know Bike Performance based on its Suspension System

For those of you who are beginners, choosing the right mountain bike should be adjusted to the type of suspension or spring installed. Full suspension will be more suitable for more extreme tracks, while the hard trail can be used for everyday use. Let's dissect the differences one by one..

Full Suspension (Soft Tail): Capable of Damaging Impact when Jumping

This type of bicycle has a suspension in the frame so that it is more capable and strong to absorb impacts when the bicycle jumps. However, the compensation of the full suspension system makes the weight heavier due to the addition of suspension on the frame. Full suspension bikes are not recommended for those of you who want to go down smooth tracks. The suspension also causes the bicycle to move slower because some of the pedaling is not channeled into forward motion, but up and down motion. For those of you who like cycling activities on extreme terrain, a full suspension system will be more suitable to choose from, such as perforated and rocky tracks, or the like.

Hard Trail: Lighter Weight for Non-Extreme Roads

For those of you who like flat terrain, the hard trail type will be more comfortable to use. Hard trail bike frames are made rigid without suspension to make the bike run smoothly and lightly. On this bike, the maximum suspension is only found on the fork or front suspension, while the other connections will be permanently connected. These types of hard trail bikes are designed for less extreme tracks, such as rocky but pothole-free trails, or on terrain where jumping is not required. This type of mountain bike is also the most widely found on the market, the price is also more affordable than soft tail bicycles.

Choose the Bike Type based on the Track You Want to Pass

An aspect that is no less important for your consideration is determining the track to be skipped. The need for the right bike may vary depending on the terrain. Here we present several types of bicycles that are suitable for certain terrains.

Trail: Perfect for Beginners Who Want to Go on Light Trails

On a trail type mountain bike, the suspension component is embedded in the center of the frame to provide the ability to pass through slightly rough terrain. The track that can be passed by a mountain bike trail is more varied when compared to the XC or cross country type. There are also many trail types that are designed in full suspension, but some still prioritize the hard trail model. The suspension system on this bike has a travel between 120 to 140 millimeters. For novice cyclists who want to try out a slightly challenging terrain, the trail type is ideal to choose from.

Cross Country (XC): Ideal for Uphill, Sharp Bends, to Semi-Extreme Terrain

This type of cross country bicycle (XC) has a very light weight and is designed for those of you who need more speed when cycling. This type of mountain bike is further divided into 2, namely XC Race Bikes and XC Trail Bikes. What's the difference between the two? XC Race bikes are designed to be simple and lightweight. The weight will be directed heavier forward to accelerate the bike's speed. This type is not designed for jumps and landings, but rather for steep climbs and turns. While XC Trail Bikes have a heavier weight, but are able to traverse muddy terrain to hard ground.

All Mountain (Enduro): More Suspension for Challenging Trails

The all mountain MTB type is designed almost similarly to the XC Trail Bikes, but has a more robust design and has more suspension. Complete suspension makes it capable of going through tougher terrain than the XC Trail Bikes, such as steep and complex tracks. Another advantage of an all mountain enduro mountain bike is the wider tire size and better grip feel. For those of you who like to go down more challenging paths, this type of all mountain bike is ready to fulfill your satisfaction every time you ride.

Downhill (Park Mountain): Descend the Hills and Mountains Very Fast

As the name implies, this type of bicycle is intended to bulldoze derivative roads such as hills or mountains. The derivative in question is a derivative that requires high speed and is tortuous, so it will be less comfortable when used for cycling on urban streets with minimal rocks. Hilly descents require intense plunging and jumping, so this bike is equipped with shock absorbers. The suspension travel of 200 millimeters allows it to land easily from a height of 2 meters or more. The frame itself is deliberately designed to be large in order to increase durability.

Adjust Frame Size to Your Height

Adjusting the size of the frame with height is often considered a trivial thing so it is rarely a concern. In fact, this adjustment will add to your comfort when cycling. The right frame size for a person can be determined from his height. For those of you whose height is less than 170 cm, the choice of frame will be more appropriate in size S or 16". 171-175 cm tall ideal with an M or 18” frame. Whereas height above that will require size L or 20". Psst.. in fact, a smaller frame size will be more comfortable to use, you know!

Check Wheel Diameter and Other Components such as Brakes

The wheel diameter on a mountain bike is usually 26 inches. However, recently the 29-inch wheel diameter has become popular among cyclists. Wheels with a size of 29 inches have advantages in speed and the ability to move through various terrains, you are also more comfortable using them on urban streets. In addition, also pay attention to the braking system. You can choose between 2 types of disc brakes, hydraulic and mechanical. Hydraulic brakes use oil, while mechanical brakes use cables. Bikes with more affordable prices usually still rely on cables for the brakes (mechanics). If your hobby is cycling, then we recommend the hydraulic type with stronger braking.

Mountain Bike History

This mode pops up around 50/60, when a group of young cyclists begin exploring the rails and slopes of the California mountains. We're not saying that no one has ever ridden his bike off the road, but at this point it's starting to have a bigger impact, thus also giving rise to the first modifications to the bike for this sport's practice. The names that stand out in this fashion due to Mountain Bike's “parents” are Tom Ritchey and Gary Fisher, who were the first to start bicycles for Mountain Bike. At first they started using the cruiser frame (often seen on the Schwinn) and upgraded the brakes, also use thicker tires. Currently both have their own brand of bicycle of this type, so that it becomes a reference in this environment.

Olympic Mountain Bike

With the rapid growth in popularity of this sport, it soon became an Olympic modality, more specifically the Cross Country variant. This variant has its own rules and regulations that do not always apply to other events outside the Olympics, as it does to other sports.

More recently, in 2008 at the Beijing Olympics, another variant of Mountain Bike, BMX, was also added.

The Main Difference Between Road Cycling and Mountain Bike

The biggest difference we all notice is the type of soil. When cycling on the road, the entire route is carried out on the road, and most of it is asphalt. In Mountain Bikes, you also drive on road or asphalt, but there will always be very few. Dirt roads, mud, descending, climbing, twigs, rocks, … are the things that characterize this sport. Another difference is the amount of protection. As on the Mountain Bike, many variants are for descending and/or climbing dirt trails with all sorts of obstacles, greater protection is required to avoid injury and injury in the event of a fall, and this is much more likely than road biking. Motorcycles have also changed many roads (which Mountain Bikes vary greatly between variants) having a more reinforced structure, rear or complete suspension for easier driving and more effective brakes, among others.. Finally, when Mountain Bikes are built on rails, there's no way to get quick support from anyone in case of damage, so each of these cyclists usually have reasonable knowledge of their bike and how to get things done in time so they can move on. faster test

Mountain Bike Variant

There are a large number of variants of this sport, some of which even organize and organize tests for them. Let's name and describe the most common and popular variants:

Cross Country

This is the oldest mountain bike variant, which is the one from which all these movements originate. As we've mentioned, their rules vary from trials, with the Olympics even have their own rules. Usually done in closed courses, where all the cyclists depart at the same time and the route consists of climbing, descending, more technical sections, etc. so as to test the athlete and show how complete he is. The person who reaches the goal first wins.

Downhill

As the name suggests, its main feature is to make hills downhill with jumps, tight corners and all kinds of obstacles. The cyclists go separately and the person who completes the course wins in the shortest amount of time. This variant is very dangerous due to the high speed of descent and therefore also uses more protection such as Full-face helmets, knee pads and even some sort of chest-protecting vest. It is not practiced like other variants although it is quite popular mainly because of its high cost of going on a motorbike downhill which is quite expensive and then a lot of elements of protection are required as well.

Trial Trip

This mix is ​​a bit of free time with competition. By this I mean that there are no trial rides only professionals, practiced by cyclists of all Mountain Bike variants and even amateurs. It is characterized as having a long road, and perhaps even lasting days, and connecting from point A to B. This test is usually more lively by connecting from one city to another, such as a cycling road where the viewer can see the curb or rail.

Freeride

This is a recreational version of Downhill. It's not always a downhill road like going down a hill but also has adrenaline-pumping and spectacle-pumping obstacles and jumps. Bikes for Freeride are often slightly different to Downhill. Free rides can also be done in the middle of the city, on sidewalks, stairs and sometimes some temporary artificial jumps, called Urban Assault.

4X

4X is very similar to BMX, it is also built in early 4 elements, and aims to achieve the first goal in order for the opponent to reach the goal. This course has inclined curves as its main feature.
