How to choose the best mountain bike?

Mountain biking can become a faithful companion not only on difficult terrain but also in the city. Here are our buying tips on how to choose a good mountain bike. If you don’t want to invest in a bad project, take a look at our guide with some useful indications.

Purpose of use

Mountain bikes are very complex today and those who are about to buy one find themselves in front of a sea of ​​mysterious acronyms. Let’s do some clarity.

The mountain bikes can be cross country (XC), trail all mountain (AM), Enduro, downhill (DH), electric. As you can see, there is a wide range of choices for every need. It is therefore important to understand first how you plan to use it.

  • The XC has only the front suspension, are therefore light, excellent for climbs and plains, less for the descents: a bike for fun, recommended for beginners, except the XC marathon, designed for long distance races.
  • MTB trail bikes are generally more versatile and complex and Enduro bikes are even more excellent for enthusiasts who are already able to tackle any type of track without problems, but less suitable for beginners.
  • If you are approaching the world of mountain biking now, you should also avoid the DH that expresses the maximum performance on the downhill and on very technical routes.

The materials

The materials with a mountain bike are made are three: steel, aluminum alloys and carbon. Steel is a material that never goes out of style, and capable of guaranteeing maximum strength and durability over time. It is also very economical.

Aluminum alloys are popular because they guarantee the necessary rigidity without making the structure too heavy and the price remains accessible.

But the best brands are those made of carbon that for several years now has established itself on the market for the exceptional properties that consist of the combination of lightness, strength and the possibility of having rigidity and flexibility in the places where they are needed.

Not all carbon fibers are the same and therefore the price can vary significantly but always remains much higher than the models with steel or aluminum frame.

Wheel diameter

Better the 26, 27.5 or 29 inches wheels? The 29-inch ones are the latest arrivals on the market. They are making a name for themselves in all specialties but they are particularly suitable for the less experienced because they are more stable and safe.

26-inch wheels are ideal for those who want to save money but it is less and less popular for the benefit of 27.5-inch. And it is more recommended for experts because they are suitable for everywhere. However, you will find different size of wheels on the market.

A rider who is looking for more speed will go for 29-inch wheels, while someone who prefers handling will choose 27.5-inch wheels. Note that large wheels are able to tackle major obstacles.

Braking system

In mountain biking, the brakes are extremely important. An effective, efficient and safe braking system is needed. The simplest bicycles in components and therefore in cost have v-brakes. However, these force us to tight the levers and brake in more time. That is why they are best recommended for disc brakes. The bikes vary in price depending on the disc brake they have, whether mechanical or hydraulic, from the most basic to the top of the range.

I recommend hydraulic disc brakes because they are quite comfortable and efficient when braking. In addition, they need less pressure, and these have an adjustment button to zoom in and out depending on the length of our hand.

How to use a mountain bike

There is an important difference between cycling and mountain biking. Mountain bike is intended for those who want to be in full contact with nature and become one with it. Mountain biking experiences sensations that have little or nothing to do with a simple bike ride. Because it means going everywhere, since there are no roads or cycle paths needed but only a great desire to pedal.

Equipment to keep on hand

Owning a mountain bike implies always having a minimum of equipment available. A good pump regulates the pressure of the tires, and it is good practice to always carry it with you. Dry Teflon oil to lubricate the gearbox and the chain, the classic tools such as screwdriver, Allen screws, pliers and everything that can be used for bike maintenance.

A stand for very convenient for maintenance when the mountain bike is not in use. Finally, a bicycle rack to load the mountain bike onto the car and reach the places chosen for your rides.

Safety is very important

The first thing when you go mountain biking is to do it in absolute safety. Therefore, the helmet must always be kept in the head and well fastened. Use gloves. And always carry a spare inner tube with its inflator. It is vital to have a chain stretcher and a false link because breaking the chain is always to be taken into account. Don’t leave your cell phone at home and make sure it’s well charged.

To prevent an accident, it is always better to go in a group. It could save your life. In this regard, always let someone tell you where you go and the course you take. You can use a handlebar GPS.

Don’t ask too much about mountain biking

When you go mountain biking, do it judiciously, in the sense that you don’t ask your bicycle for more than it can give. In other words, do not put it under greater stress than it can handle. If you want to speed on demanding and bumpy descents, you must have a professional bike.

Frequent Asked Questions

How to start mountain biking?

First of all to start with a rental bike in order to understand if this type of activity can really for you. Before proceeding with an expensive purchase, it is good to start with a few hours of laps, which include a mix of asphalt and the path and which are calibrated with your physical preparation.

Also get a minimum of technical clothing, which essentially consists of a short, a shirt and a jacket for wind or rain. Avoid too steep or too long routes and calibrate your efforts gradually.

How much does a mountain bike weigh?

The weight of a mountain bike varies essentially according to the material with which it is made and greatly affects the level of performance. In general, the values ​​are between 10 and 18 kg approximately. Note that the heavier the bike, the harder it will be to climb.

How to remove the rear wheel?

This aspect essentially depends on the attachment system provided by the model you have purchased. In recent years, facilitated systems are increasingly common, such as the quick release system. The procedure therefore becomes very simple, because it only requires the opening of the quick release lever: this must be then unscrewed and extracted from its housing.

If a pivot is provided and not the lever, the only difficulty could be that due to the presence of rust or debris, which must be therefore eliminated before proceeding.

How to lift the handlebar?

In order to have the right comfort when using the mountain bike, the handlebar must be at the same height as the seat. It must be adjusted so that the leg can fully extend.

Many models have an adjustable handlebar, otherwise you will have to insert shims at its base so that the subsequent assembly will lift it compared to the previous position. This solution is always seen in a more positive way, because the adjustable handlebar makes the structure slightly less stable, especially if you have very rough and steep paths in mind.

What is the price of a mountain bike?

Within the Mountain Bikes market, you have prices for all tastes, whims and pockets. And you will find very low and affordable prices for basic mountain bikes. You will also find high prices for very innovative bikes that are usually electronic.

This ultimately translates to you can find Mountain Bikes from about 300-9000 dollars. Well, it all depends on the type of Bicycle, prices vary a lot, but what is clear is that those of more prestigious brands are more expensive.


As you can see there are many types of Mountain Bikes so deciding on one or the other is not an easy task. As we have mentioned within the ten options that we gave you, you should focus on what you really need, and what is your budget.
