Buying Guide For Best Mountain Bikes Under 400 Dollars

Buying a good mountain bike can allow you to enjoy the experience to a great extent. Once you have started experimenting with mountain biking, buying a high-quality mountain bike will be a must. There are a lot of types and models available on the market and choosing the appropriate one can be a bit tricky. In this section, we offer some tips that will help you choose the best mountain bike:

The Suspension Type

Rigid bikes are not that common. They are less expensive and easy to maintain. But most riders would rather ride bikes with suspension because they are more comfortable. Hard tail bikes have a front fork that is designed to absorb the shock from the front wheel. In this model, the back wheel will not have suspension. These bikes are not difficult and sometimes have a lockout feature. You can use the lockout when you are comfortable with using a rigid bike. These bikes allow for power transfer between the pedal and the rear wheel. These bikes are excellent for different mountain biking experiences unless when you are going on a downhill trail.
Full suspension bikes feature a front fork and rear shock absorption to keep you comfortable despite the impacts of the trail. This reduces the impact on the rider and gives you a comfortable riding experience. These bikes are great but can lose some of the energy as you ride uphill. These bikes usually can lock out the rear suspension for better power transfer.

The Wheel Size

Wheels comes in different sizes. The bigger the size of the wheel the faster the wheels will go. The wheels will roll easier even through bumps. Smaller wheels will offer maneuver on rough trials but you might not be extra comfortable.

The frame material

When you are looking for a reliable mountain bike that is both durable and fast. Aluminum is one of the most popular materials because it is very lightweight yet very sturdy. Aluminum doesn’t rust or bend even on the toughest trails. This also means that the bike will be fast for a great mountain biking experience.
Carbon steel is another sturdy material that is less expensive than aluminum. If you are willing to buy a reliable mountain bike that won’t break a bank, then you should probably consider buying a carbon steel mountain bike.

Mountain Bike Gears

The number of gears is determined by your fitness level and the type of terrain you are riding. If you are riding through difficult trails and steep hills, you should opt for more gears. If you only ride through flat terrains, then you can get away with a fewer number of gears. This means that your bike will be lighter and easier to control.

The bike size

You should always make sure that the bike is a great fit for your height and weight. A mountain bike that fits very well will increase your level of confidence on the trail. The sizing charts usually correspond to the height. If you are between sizes, it is usually advisable to go a size down rather a size up.

Easy assembly and maintenance

Most mountain bikes will not come assembled. This means that you can easily put yours together easily using a few tools. You might spend more time or even ask for the help of a professional if you are not that experienced. Some bikes can be easily maintained using the least number of bicycle tools. If your bike has quick release wheels, you will be able to maintain it easily.

Conclusion

There is no doubt that you can find the best mountain bikes on the internet. You can easily go through the Best Mountain Bikes under 400 dollars to choose one that is suitable for your needs and abilities. Mountain bikes come in different sizes and materials that are suitable for everybody out there. There are a lot of factors and criteria that will help you choose an appropriate one.

You need to make sure that you are buying a reliable product that won’t break or bend easily. Make sure that your bike is stable even through the roughest terrains. This will help you enjoy your mountain biking experience to the maximum.
