How to Choose Good Mountain Bikes For Kids

The options for top mountain bikes for kids will be plenty, but that does not mean that you can pick just any product. To help you narrow down the possibilities, below are some of the most important things to consider.

Size

One of the first things that you need to consider is the size of the mountain bike for kids. This will depend on the age, height, and weight of the rider. Below is a quick rundown of the recommended size of the bike wheel depending on the age of its user.

  • 2 to 4 Years Old: 12-inch Wheel
  • 3 to 5 Years Old: 14-inch Wheel
  • 5 to 8 Years Old: 16-inch Wheel
  • 6 to 10 Years Old: 20-inch Wheel
  • 8 to 12 Years Old: 24-inch Wheel
  • 12 Years Old and Above: 26-inch Wheel

Frame

This is one of the most important parts of the kid’s mountain bike. This will be indicative of the weight and durability of the bike. You don’t need a carbon fiber frame. It is an overkill for kid’s bikes.

Aluminum

If you want the bike to be lightweight without compromising durability, it is hard to go wrong with aluminum. Because of keeping the weight of the bike at a minimum, it will be easier for the little ones to maneuver it even on rough terrains.

Steel

This is cheaper and heavier compared to aluminum but equally durable. One of the best things about steel is that it is more forgiving. This means that kids will feel less of the impact or vibration since the frame will absorb it.

Fork

The fork is the part of the mountain bike where the front wheel is mounted. This is turned using the handlebars, which will also dictate where the bike will be going. Below are two of the most common kinds of a fork that you will see in a child mountain bike.

Rigid Fork

A rigid fork, as the name implies, is rigid. There are no moving parts. Between the two, this is lighter. It is cheap and sufficient in most riding conditions. It is also maintenance-free.

Suspension Fork

If you want the mountain bike to be more comfortable for kids, you can never go wrong with a suspension fork. It will make rides smoother, especially on rough terrains. The suspension will minimize the impact that kids can feel when riding.

Brakes

The braking system of the mountain bikes for kids is crucial for their safety. Especially as they get older and ride independently, they need highly functional brakes that can deliver exceptional stopping power as soon as they are engaged.

V-Pull Brakes

Mini V-brakes will be sufficient for most riders, especially in 16 and 20-inch bikes for kids. It is the type of brake you will see in most cheap bikes, but in most cases, it will be more than enough.

Mechanical Brakes

It offers a bit more stopping power compared to mini V-brakes, making it better for older users who are ready to step-up into a more advanced bike.

Hydraulic Disc Brake

This is the most expensive but also the best in terms of performance, making it worth every dollar. It has the most exceptional power from the three and is also the easiest to pull. This will also be more comfortable.

Shifters

Shifting can be confusing for children, so choose basic shifters that will be easy to learn. Once they have mastered using this, they can move to a more complicated shifting mechanism. However, especially if it will be the first mountain bike of the user, the shifter should be as simple as possible.

Grip Shifter

They are also called twist shifter or twist-grip shifter. With the design of this shifter, it is best for kids who have small hands, making it easier to use. They are commonly found in kids’ mountain bikes with a straight handlebar.

Trigger Shifter

This type of shifter is better for kids because it allows them to shift without additional torque. Even in adult mountain bikes, trigger shifters are better. There is no risk of accidental shifting and it also delivers a high level of precision.

Geometry

The right choice for the geometry of the bike will depend on the surface conditions and the type of ride that kids will be doing. To determine the geometry of good mountain bikes for kids, here are some of the parts that you should be looking at.

Reach

This is the horizontal distance that runs between the center of the head tube and the bottom bracket. It affects the length of the bike. When it is too long, it will be difficult for kids to reach the handlebar from their seats, making them lean forward more.

Stack

It is the height from the center of the head tube to the bottom bracket of the mountain bike. This will determine the sitting position of the kid when pedaling.

Head Tube Angle

It is the angle between the ground and the front fork. This is important as it will have an impact on the maneuverability of the bike, especially on rough terrains.

Chainstay Length

This is the distance between the rear axle and the center of mass of the rider. Longer chainstays are better for kids if they want better stability in every ride.

Bottom Bracket Height

It is the distance between the ground and the center part of the crank. Lower brackets can easily transition during turns. However, the drawback is that it can clip on rocks and bumps, which can cause damage over time.

Wheelbase

This is the distance between the front and rear wheel axles. The wider they are from each other, the more stable the bike will be. The narrower is the distance, on the other hand, the easier it will be to maneuver the bike.

Tires

The quality and performance of the mountain bikes for kids will also be largely influenced by the tires that come with it.

You can go for solid flat-free tires. They also require lesser maintenance. The problem with the latter, however, is that the performance is compromised. If you are looking for a better alternative, you should go for air-filled tires. They have excellent cushioning and grip to ensure better performance on a variety of terrains.

Style

This is one thing that is impossible to ignore for mountain bikes girls and boys. Kids will love a bike that looks good, so make sure to give them a voice on what to buy. Especially the young ones, they would most likely prefer one that is inspired by their favorite cartoon characters. As they get older, they will have changes in their preferences, opting for a sleeker style.

Conclusion

The best mountain bikes for kids will allow the little ones to enjoy the great outdoors in comfort and style! The products mentioned above can deliver exceptional performance, making them deliver the best bang for the buck.

Most parents will decide based on price, but that should never be the case. At the end of the day, you should not mind spending more if this means that your kid will have an exceptional ride!
