How To Choose A Kids Mountain Bike – Buying Guide


Size & Fit

When choosing the best mountain bike for kids, you must ensure to find the right size and fit. The two ensure that your child can effectively ride the bike for long and don’t risk pain on any body parts. The size of the kids’ mountain bike is denoted by the wheel size. 

So for example, if the bike features say the size is 20 inches, it means the size of the bike wheel is 20 inches. As a general rule of thumb, there is a standard table that guides on choosing the size and fit of the bike.  For example, a 20-inch bike caters to 2-4 year olds, a 14-inch bike caters to 3-5 year olds, a 16-inch bike caters to a 4 – 6 year old and so forth.  

It is also unusual to find kids of the same age with varying heights. Thus, many manufacturers build bikes with adjustable seat heights, so if the bike is designed to cater to kids aged 4 to 6 years old, the design can easily fit most sizes.


The frame significantly adds weight to the bike.  The two common materials used for bike frames are steel and aluminum not. Steel is rugged and lightweight whilst aluminum offers more ruggedness but is slightly heavier. The two alloys are also designed to be non-corrosive. Either choice is ideal as it allows your child to be able to handle the bike without compromising their durability. 


A fork on your kid’s bike is basically the bike’s suspension system. The best mountain bike for kids is designed with either a rigid or suspension fork. Suspension forks are built to provide added balance and smooth riding. However, they are only necessary if your child will be riding on extremely rough and rocky terrains. 

Furthermore, a suspension fork is also ideal for steep downhill riding.  A rigid fork on the other end provides support for cross country riding. A rigid fork also trains your child on more riding and navigation as it prompts them to avoid rough terrains.


The best kids mountain bikes are also built with wider tires. Wider tires provide more surface and contact to the ground thus, enhancing comfort and stability. Especially if your child will be riding under the rain or on wet terrain, a wider tire surface provides added stability. Yet, it is a good idea to examine tire width when choosing the bike for your child so you can find the best fit for the terrain they intend to ride on.


Depending on your child’s need, you don’t want to get a bike with intricate gear design to confuse them. You want to go for gear designs that offer ample functionality and versatility without confusing your child. Having a wider range of gears makes it easier for your child to tackle trickier riding such as ascending uphill or maintain high speed like in a car. 

Yet, your child must also be taught how to handle the dynamics. Many kids mountain bikes will feature a triple chainset or single gear front wheel and a large cassette in the back. 


The best kids mountain bikes are also fitted with disc or rim brakes. Disc brakes tend to be more effective as they directly apply pressure on special brake pads to stop on the wheels. However, for the child’s considerably less technical riding, disc brakes may be too much. Disc brakes will only work if your child frequents terrains such as downhill descents at an increased speed.

Kids Age

You can easily find a kids’ bike to match their age. Many manufacturers will provide their bike choices with a recommended age table. So for example, a bike size of 16 inches is ideally built for kids aged 4 to 6 years old.
