How To Choose A Mountain Bike?

Before we take a detailed look at my top 5 picks, let’s talk about the most important thing – what to look for when we are choosing a mountain bike.

If you are a novice in the biking world, all bikes probably look the same for you. But there are some important things that you should take into consideration when you pick your first bike.

Find the right bike type for you

The first thing you have to do is decide what you need the mountain bike for and where you are going to ride it. Then take a look at these bike types:

  • Trail bikes. These bikes are efficient, not very heavy, and versatile. If you need a bike for the occasional trail ride, then this is your bike.
  • Cross-country bike. If you are looking for a bike that will help you to outrace your friends, then you need a cross-country bike. They are usually light, with large wheels and they are designed for maximum pedal strokes. Such a bike is ideal for long distance riding.
  • All-mountain bikes. These bikes are suitable if you want to ride in unexplored terrains because they can handle ascents and descents.
  • Fat bikes. Choose a fat bike if you want to ride all year round – in snow, dirt, ice or even sand. They have oversized tires that provide better traction. Such bikes are an excellent choice for a beginner.
  • Enduro bikes. Suitable for fast descents, challenging terrains, and enduro racing.

Suspension for a comfortable ride

When it comes to bikes, there are three types of suspension that you can choose from:


Rigid bikes don’t have any kind of suspension. The major disadvantage is that you’ll feel every bump on the road with these bikes. But one advantage is that these bikes are very light, easy to ride and low-cost to maintain. However, they aren’t very common nowadays.


Hardtail bikes feature suspension in the front fork and no suspension in the rear. That’s why they are called hardtails. What’s good about this type of suspension is that your upper limbs won’t get so tired if you ride for a long time. A front suspension also makes steering the bike or sustaining a high-speed easier.

Full suspension

In general, bikes with full suspension are heavier than bikes with front suspension. They also tend to be more expensive than front suspension ones. However, they are more comfortable since the front and the rear suspensions absorb the shocks and cushion the rider. They are perfect for going down a bumpy hill.

Wheel size matters

While 26” wheels were a standard choice for mountain bikes before, now you’re likely to have to choose between:

  • 26” wheels
  • 27.5” wheels
  • 29” wheels

27.5” wheels provide better maneuvering power than 29” wheels, and they roll more smoothly than 26” wheels. But the 29” wheels offer better traction and more efficiency. The 27.5” are suitable for short people, while they 29” and the best fit for a tall person.

When choosing a wheel size, just keep in mind where are you going to ride your bike and what you need – efficiency or versatility.

Reliable brakes for safety

When it comes to bikes, maybe the most important thing is the brakes. After all, no one wants to find himself face down on the ground. The choice is between disc or rim brakes.

If you want reliable brakes with a superior braking power, look for disc brakes. They cost more, and they add weight to the bike, but they don’t require you to apply much finger effort on the levers in case you need to stop immediately.

Rim brakes, on the other hand, are less expensive, but they are of no help on a muddy road, and they wear the wheel rim with time. Their advantage is that it’s to check them for brake pad wear than disc brakes.

Now, let’s take a look at our top picks and discuss what makes them such a suitable choice for you.

    While it’s true that all of these mountain bikes are of excellent quality, there is one that I feel is superior to the rest of the pack. I’m talking about the Vilano Blackjack 29er mountain bike. There are several reasons why I put this bike first on my list of the best mountain bike under 300$:

    • the 29” wheels
    • the mechanic disc brakes
    • front suspension with lockout
    • 24 speeds
    • the Shimano 8 speed EF-51 integrated shifter
    • the elegant design
    • it’s suitable for a wide range of terrains

    As we already said, 29” wheels provide better traction than smaller ones. But the dealbreaker is that you’ll cross most of the obstacles on your path without ending up on the ground. The 24 speeds and the mechanic disc brakes, on the other hand, mean that you have more speed options and sufficient braking power at the same time.

    Moreover, since this is a front suspension bike, it will not require so much maintenance as a full-suspension one.
