Factors To Consider Before Buying Mountain Bike:

Factors To Consider Before Buying Mountain Bike

The purpose of this mountain bike buyer’s guide is to help you buy a mountain bike that you will love.

Pick The Right Size

Size is the most important factor one should consider when purchasing a mountain bike. Make sure the bike you choose is a perfect fit for the rider. If not, the rider may end up with weird angles, poor posture, strained back.

There are two primary sizes that you should consider when choosing a new bike – frame size and wheel size. Both are vital in terms of the performance and overall feel of your ride.

Bike Fit

Adjusting a cycling position takes some getting used to and experimentation. Try out different stem and handlebar options until you find something you like.

Comfortability

It’s a good idea to give a new bike a test ride before buying it. This gives your kid a chance to experience the bike and make sure it fits their needs and preferences. And, once you find the perfect fit, you can rest assured that your child will enjoy riding it.

But if he feels uncomfortable and faces problems in balancing and handling speed, you can look for another one.

Weight

Weight can be a big factor in a child’s choice of a bicycle. If the bike is too heavy, your child may not have the strength to keep the bike upright and moving forward. This could lead to injuries or even result in the bike crashing. 

Components And Quality Of The Mountain Bike

Components And Quality Of The Mountain Bike

But the most important factor of all is the quality of the mountain bike you want to purchase. When choosing a Mountain bike, it is very important to pay attention to the quality of the components and construction of the frame.

There are many components and features in an average bicycle but the quality of the overall bike is determined by the components and features that the frame is equipped with. So pay close attention to this aspect of your product!

Frame 

What material is in the frame of a mountain bike? We’re going to give you the skinny on the different materials used to create mountain bike frames today.

Mountain bike frames majorly come into three types:

  • Aluminum

For bike frames it’s usually the cheapest and easiest material to work with – 6061 aluminum is commonly used. Alloy is corrosion-resistant and lightweight. And because it’s so popular, you’ll find lots of great designs made in aluminum. More and more bikes are being made out of 6061 alloys because of their reliability, affordability, and weight.

  • Steel

Steel is a metal that’s dense, strong, durable, and can withstand a wide range of temperatures. But, it costs more to produce than aluminum. Steel frames are heavier as compared to aluminum frames.

  • Carbon

Carbon is a composite material made out of layers of carbon weave. Carbon is an incredibly versatile material that can be used in a variety of different applications. It is strong, lightweight, and more durable than steel and aluminum. While carbon fiber can look amazing, it’s also prone to cracking. However, its biggest downside is that once you crack your frame, it is no longer safe to ride.

Fork

There are essentially two types of forks for kids’ mountain bikes – rigid and suspension. Suspension is a way of adding comfort to a bicycle.

The suspension is there to absorb the bumps and rough stuff of the trail, but it does nothing for the ride if you are on smooth asphalt.

A rigid fork is recommended for all-around riding, especially cross-country riding. A suspension fork works best for downhill riding on rough paths. A rigid fork is the traditional form of a fork. They are maintenance-free, lightweight, and come at a cheaper price.

Tires

Tires on a mountain bike should provide the best traction, comfort, and stability. Wide tires are best for rough terrain while narrow tires are best for smooth paved areas. You’ll want a tire that has a good “profile” for your terrain.

Gears

While it’s important to have gears on a kid’s mountain bike, it can become a nuisance for younger riders to understand just how to use them.

Knowing how to use the right gearing will help to make your cycling experience more efficient and comfortable.

Brakes

Mountain bikes commonly use either rim brakes or disc brakes. With rim brakes, you squeeze the rubber brake pads on the side of the wheels.

In comparison to rim brakes, disc brakes feature rotors mounted on the wheels with special brake pads. They work by applying pressure by hand or pneumatically.

Kids’ bikes have been fine with regular normal brakes for a long time. You don’t need disc brakes on your kid’s bike. In fact, you might want to consider replacing them entirely.

Budget

When buying a kid’s bike for your little one, don’t feel pressured to overspend. If your kids want a new bike, make sure it fits their needs and budget. There are some great, affordable kid’s bikes available. You’re going to want to make sure you get a bike that works for your child and will serve them well.
