How to measure a kid’s bike?

There is always a question of how to measure a kid’s bike. If you are looking for a kid’s bike, then you have to know the height and weight of your child. You can also look into the age of your child, but this is not as important as height and weight. Many parents misguided themselves by purchasing the kid’s bike according to the baby’s age. But baby’s age cannot be a standard parameter to buy a properly sized bike. It’s because, at the same age, some kids may grow taller whereas others may remain shorter. Therefore, purchase the bike according to the kid’s height, not by his/her age.


However, you can go to your local bike shop and see what they carry in kids’ bikes. Before going there, you should know what features you want your kid’s bike to have. This way, it will be easier for you to find the right kids’ bike for your child.


It does not matter if it’s a 10-speed, trike, BMX, cruiser, or mountain bike; one thing is for sure: The first time your child drives off on his or her own bike, it is a momentous occasion. It marks the end of his or her training wheels’ days and the beginning of his or her journey into the world of bicycling. Now that your child is venturing into this new realm, you may be wondering about sizing kids bike correctly.


Bike sizing is measured in two parts: the frame and the wheel size. In order to make sure that your child will be safe and comfortable on their bike, it is important to know how to properly measure a kid’s bike.


The most common mistake people make when purchasing a kid’s bike is that they tend to think of the wheel size rather than the frame size. The wheel size is an important factor, but only if you are buying a full-sized bike for your child. If you are looking for a balance bike or a training bike, however, the wheel size isn’t as important as the bike frame size.


Why bike measuring is one of the most important things for parents to do when buying a kid’s bike? Because a perfect bike size helps the children to ride the bike comfortably and with ease.



However, there are certain aspects to measure before buying a bike for your child.

The first thing to consider is the size of the frame. Make sure that the frame is neither too small nor too large for your child’s height and age. Frame size is usually measured from the center of the bottom bracket to the top of the seat tube. To measure this, stand your child next to the bike and move them into an upright position while they hold the bike handle.



Then get down on the floor and measure the inside leg of your child (from the crotch to foot). Compare that measurement with the bike’s seat height. The seat height should be about 1-2 inches higher than the child’s inside leg measurement. Remember to adjust this number according to whether or not your child uses shoes with heels.


You cannot measure a kid’s bike by using an adult measuring tape or ruler. Kids bikes are designed for kids and thus the measurements must be taken differently.


There are several different types of bikes; BMX, mountain bikes, road bikes, hybrids, and kid’s bikes. Kid’s bikes come in different sizes to match the height of your child. It is important to choose a bike that fits your child well so they don’t have any problems while riding it. Here are some useful tips on how to measure your kid’s bike correctly.
