Things To Consider When Buying A Kid’s Mountain Bike

If you are to take home the right bike that will satisfy you and your child, the following are points that you ought to consider. These include;

Bike Sizing

Kid’s bikes are usually measured by the wheel size and not the frame size. The most common sizes are 12 inches, 16 inches, 20 inches and 24 inches. Makes sure that the child you are buying the bike for can stand on the top tube of the bike, with the two feet on the ground and without the top tube pressing into him or her. The child ought to feel comfortable and in control at all times.

Most parents make the mistake of buying a large bike for the kid to ‘grow into it.’ Doing this can kill the kid’s zeal and confidence, and even set them back concerning riding skills because it will be an uncomfortable and dangerous bike. I highly recommend a properly sized bike to make the experience a lot more fun for they are simpler to handle and less dangerous.

Training Wheel Bikes

Bikes with training wheels can do a lot for your kid in terms of giving them that confidence boost they might need to start riding on their own. Once they get that, the training wheels can be removed.

The Brakes

These are the most important mechanical part of a bike. You want your kid to have control of the bike getting stopped. Kids’ bikes either have coaster brakes, the kind that is on the back wheel and are engaged by pedaling backward, and handbrakes, usually engaged by gripping on the handlebars, which in turn pinches brake pads against the rim of the wheel hence stopping the bike. Some models have both.

The smallest kids’ bikes have coaster brakes, because of their limited hand strength and hand size. Until your child’s hands are strong enough to use a handbrake effectively, they should rely on coaster brakes. For some experience, you could put them on a bike with both brakes so they can get used to hand brakes because most adult bikes can only have handbrakes.


I would highly recommend lots of research before you go into the market to look for that bike to take home with you. All the things you would love to know is readily available online, so you should benefit from that. However, you need to be cautious since some websites are solely for the purpose of promoting a certain model so they might be biased and focus only on the pros.

Read a lot of customer reviews from previous and current owners of the models you might have narrowed down to, and also read lots of reviews like this one where all the research and testing and hard work has been done for you, so you do not have to. These will help guide you a few steps closer to your perfect bike and also, educate you so you can make decisions for yourself from an educated point of view.

Final Words

It is crucial to note that some of these bikes do not come assembled and some come semi assembled. If you have no clue how to assemble a bike, make sure you have the help of an experienced friend, or you could head on over to the bike shop for professional help. Make sure all mechanisms and moving parts are okay before you send your kid off on their first ride because their safety is paramount.

All of these are great beginner bikes for children, so any of them will be a great choice. They all got the most important specifications that will satisfy the parent. After tuning it beforehand, your little one is ready to explore the neighborhood streets and paths on two wheels!​
