Things to Keep In Mind

When purchasing a youth mountain bike, there are a few things to consider. Many considerations apply to the bike itself, but others are more about knowing your rider and what they need.

If they are just starting, start them off with a quality bike with less sophisticated features like the Ninebot Kids Bike by Segway. If they want to get involved with mountain biking more seriously, purchase a bike like the Rocky Mountain Reaper or the Commencal Clash 24.

Here are a few tips when looking for the best youth mountain bike:

  • Choose the correct frame size. There are many tools for measurements available online or at your local bike retailer.
  • Choose the correct tire size. Plenty of information on the best tire size for the bike is available online or at your local retailer.
  • Choose between hardtail bikes or full-suspension bikes, depending on your needs.
  • Be sure to look at suspension quality, not quantity. It is best to get quality over quantity in this case.
  • Stay within your budget!
  • Keep the future in mind. If you want the rider to keep this bike for a while, you should buy a bike that will grow with the biker.

Frequently Asked Questions

What age is a 24-inch bike for?

These bikes are most compatible with kids aged 8-11 years old. However, always try out measurements before purchasing. Some kids could use a bigger or smaller bike despite their age.

How do you measure a mountain bike for a child?

Measure the wheel diameter in inches using the wheel’s outer diameter. The tire must be installed on the rim when measuring. The smallest kids’ bikes begin at 12 inches and go up to 24 inches. After a 24-inch wheel, the child may be ready for an adult-sized bike!

How much do mountain bikes cost for kids?

True mountain bikes are more expensive than regular bikes due to their complex components. These components, like suspension and good fork, are necessary for the mountain bike to be comfortable and efficient on alternative terrain rides. You can expect to pay between $500 and $5,000 for a good quality youth mountain bike.


Like any other large purchase, choosing a mountain bike is a decision you should put a lot of thought into. It is crucial to choose a bike that fits the physical measurements of your rider.
