The best kids’ MTB bikes with full suspension open up the world of mountain biking for your children, making trail riding more accessible, enjoyable, and safer.

With a kids’ full-suspension mountain bike, handling, comfort, and control are improved on trails when compared to a hardtail MTB or non-suspension mountain bike because the geometry and components are for a child’s body shape and ability.

Finally, like with an adult’s bike, try to find the lightest model within your budget, as this will be easier and more fun to use. Keep reading to learn more about buying the perfect kids’ full-suspension MTB.


XS-size frame vs. kids’ specific frames

An XS full suspension mountain bike is for short adults.

This difference is vital to understand because adults have considerably different proportions and build compared to a child of equal or similar height, such as hand size, shoulder width, and grip strength. In addition, a child-specific saddle and standover height are essential aspects of a kids’ bike.

Should you buy a size bigger so your child can grow into their bike?

No.

When purchasing a bike for your kid, you want to buy one that fits their current height and inseam length. Additionally, you want them to sit on the saddle and be able to touch a foot on the ground.

Buying a bike that your child will grow into is a mistake and can negatively affect your child’s experience. In addition, a poorly fit bike can cause injuries or be unsafe to ride.

Wheel Size  Recommendations

According to Prevelo (A kids’ bike-specific brand)

Wheel size | Age | Inseam
12″ | 1.5+ | n/a
14″ | 3-5 | 13-16.5″
16″ | 4-6 | 15.5-22″
20″ | 5-9 | 18-23″
24″ | 7-11 |23-28″
26″ | 10+ | 25″ +

Note that these measurements are averages, and you should measure your child’s inseam to ensure you have the right fit.

When choosing a full-suspension mountain bicycle for your kid, ensure it is a good fit when you make the purchase, that it’s light enough, and designed for how your child would like to use it. By doing this, you set them up to succeed wherever the mountain takes them.
