How to Determine the Right Bike Size for Your 4-Year-Old

As we all know, children don’t grow the same way. When trying to determine the best size bike for a 4-year-old, the most integral factor to consider is your child’s height.

Just because a bicycle can accommodate one 4-year-old child doesn’t mean it can accommodate all 4-year-olds.

Most 4-year-old children measure somewhere between 3′ 7″ and 4′ 0″, and the ideal bike size for that height range is a 16″ bike. If your kid’s height exceeds the specified height range, you want to opt for a 20″ bike. If your kid is shorter, on the other hand, you should go for a 14″ bike.

Another crucial factor to take into consideration to ensure the perfect bike size is the kid’s inseam. Ideally, the inseam should be as long as the Bicycle’s minimum seat height, at least. This helps ensure that your kid is able to put their feet flat on the ground rather than their tippy-toes.

How to Choose the Best Bike for Your Kids

To ensure an enjoyable riding experience for your kid, several factors should be considered, from the size and weight of the bike to the brakes and frame. Heed the following.


For 4-year-old children, 16″ bikes would be the most accommodating options. If your kid is a bit taller than the specified height range for 16″ bikes, which is 3’7″ to 4’0″, you should opt for a 20″ bike. Per contra, if your child is shorter than 3’7″, you should look into 14″ bicycles.

We’d like to point out that there are two main types of bikes that you’ll find on the market: pedal bikes and balance bikes. If you go for a pedal bike, you must make sure that the seat height is equal to or just below your child’s inseam measurement to ensure proper foot positioning.

We feel the need to stress the importance of getting your child’s inseam measurement right, as this will help ensure a safe riding experience since it will allow your child to plant their feet down to steady themselves or stop the bike when necessary. This is crucial when learning to pedal.

If your 4-year-old kid is already a master pedaler, then we strongly recommend that you set the bike’s seat 2″ higher than your child’s inseam measurement. This will help ensure a much more comfortable pedaling experience. It will grant your little pedaler better control over the bike.


Of course, the lighter the bike, the easier it will be for your little cyclist to ride it for long without getting tired. Heavier bicycles are pretty hard to balance and control. Generally, you want to make sure that the bike’s overall weight doesn’t exceed 30% of your child’s weight.

As you can see in our list of the best bikes for 4-year-old children, we only covered lightweight bikes that wouldn’t be a burden for your child to manage and balance. There are various other high-quality bicycles on the market, but they’re not light enough to ensure happy riding.


Most 16″ bikes tend to be equipped with coaster breaks, also known as back-pedal brakes. But the thing about these brakes is that they can hinder your child’s learning experience in pedaling because most children tend to pedal backward to regain their balance.

When your child pedals backward on a bike that’s equipped with coaster brakes, the brakes will be activated, slowing down the bike or stopping it completely. This is mainly why we advise that you opt for a bike that doesn’t feature coaster brakes and utilizes hand brakes instead.

Keep in mind that mastering how to use hand brakes can take quite a bit of time. However, once mastered, hand brakes offer a more convenient and effective way of slowing down a bike. If you feel like coaster brakes are more suitable for your 4-year-old, by all means, go for it.


The design of the bike’s frame has a significant influence on the overall performance of the bike, and it feels to ride it. If your kid is a total beginner, look for a bike that puts the rider in an upright position. This position will feel more natural, ensuring an enjoyable riding experience.

If this isn’t your kid’s first bike, you may want to consider a bike design that requires the rider to lean forward to grip the handlebars. This position places the rider in a more aggressive stance. We advise going for the upright design to ensure maximum safety for your child.

Tip: If your child is a total beginner and is having trouble maintaining stability, you might want to invest in training wheels to help them learn how to pedal and brake safely. Once your child masters how to pedal and brake properly, you can then remove the training wheels.


The market is home for many high-quality bikes, but it’s also home for many knockoff products that have nothing to offer but a tempting price tag. We recommend you steer clear counterfeit models as they tend to be of low quality and can put your child’s safety and wellness in danger.

High-end bicycles tend to be a bit costly, but they’re also a lot more durable and lightweight than low-end alternatives. Also, they tend to flaunt frame designs that allow for more comfortable riding. All in all, a high-quality bike will compensate for its steep price tag in the form of greater longevity.


As we were conducting our research, we came across a few questions that seem to be causing some confusion. This part of the article attempts to clear the fog by addressing these questions.

How to know the appropriate seat height?

To know the appropriate seat height, you have to measure your child’s inseam. The highest part of the seat should be set to the measurement you’ve got. To double-check, make sure that your child is able to plant their feet on the ground while still sitting comfortably on the bike’s seat.

Are kids bikes equipped with gear systems?

The vast majority of bikes designed for kids are single-speed bikes, which are designed to teach the rider how to balance and break a bike. Getting your 4-year-old a multi-speed bike is not a sound decision, as it’ll be extremely difficult for your child to learn how to handle it.

Which braking system is ideal for my kid?

Coaster brakes the easiest type of brakes to learn, which by default, makes them optimal for kids of around 4 years old. However, if your child is an experienced rider, we recommend looking into bikes that have handbrakes since most cyclists like to balance themselves by pedaling backward.

Conclusion and Best Offer

We’re quite confident that any of the bicycles mentioned above will do your child justice. One product that stands out the most in our eyes is the RoyalBaby BMX Freestyle Kids Bike.

Best Offer

Our best bike for 4-year-olds: it’s lightweight, secure, comfortable, easy to assemble, and optimal for both boys and girls.
