What is the best bike size for 7 Year Olds? The diameter of the wheels of children’s bicycles is used to determine their “size.” The smallest pedal bikes have wheels as small as 12 inches in diameter, while the largest pedal cycles have wheels as large as 24 inches. Your child is ready for 26-inch wheels when they are old enough to ride an adult-sized bike, but some bike manufacturers do offer smaller “youth” size 26-inch bikes for children under the age of 12. Balance bikes, on the other hand, maybe purchased with wheels as tiny as 10 inches, but the majority of balance bikes have wheels between 12 and 14 inches in diameter.

One of the most effective ways to begin narrowing down which size bike your kid needs is to identify what size wheels they are most likely to require. Probably since we are basing it on a range of ages for youngsters of average height, I say probably.

Best Bike Size for 7 Year Olds

If your kid is very little or extremely tall, they may need a bike that is either smaller or larger than the broad range we recommend below. Don’t be concerned about it; this is only a starting point, so obtain a general sense of what size wheels your child will most likely need.

What’s The Best Bike Size for 7-year-olds?

Keep in mind that this is just the beginning of the conversation. Take a look at this chart to get a rough idea of what size bike your kid need, but don’t forget to follow the instructions below!!!

Measure Your Child’s Height and Inseam

The next step is to take your child’s height and weight. Don’t skip this step or make an educated estimate!

It should still be possible to get measurements from the child’s parents if the bike is being purchased as a present for him or her. If you have to keep it a secret, make up a story about how you’re making clothing or whatever.

Measure both the inseam and the height of your kid. When taking your measures, you should do it in inches (or convert them to inches after you’re finished). Note down all of your measurements and have them handy for our next step.

Look Up the Specs for the Bike (or Bikes) You are Interested In

Just because you believe your kid will most likely need a 14-inch bicycle does not imply that ANY 14-inch bicycle will fit them. Stand-over heights and minimum and maximum seatpost heights vary from bike to bike and from model to model. If possible, opt for a bike that will offer the greatest fit for your child’s size and weight.

Not all bicycle manufacturers provide information on the standover height of their bicycles. If they do, though, you should measure it against the inseam of your kid.

Your kid will be positioned in this position while standing with one leg over each side of the bike at the standover height. The standover height is measured from the top tube of the bike frame. This implies that your child’s inseam must be AT LEAST as tall as the standover height in order for him or her to participate. The ideal situation would be for your kid to have a bit more room than that in order to operate the bike comfortably.

What To Do When Your Child Is In Between Sizes

Selecting a bike for your kid is very straightforward if he or she is at or near the bottom of the acceptable height and inseam for biking. It’s more difficult when your child’s height and inseam are at the higher end of the suggested range for a bike.

When this occurs, we hear from a large number of parents who are concerned that the bike will not last long and that their kid will outgrow it soon. This is a legitimate worry, given that neither bicycles nor money grow on trees in the wild.If your kid is dangerously near to riding the next size bike, I usually advise parents to go ahead and upgrade their child’s bike. If your kid already understands how to pedal and is a competent rider, this is particularly important to consider.

You are the one who is most familiar with your child. What about their athleticism and their ability to handle a larger, heavier bike? What makes you think they’ll feel confident standing on their tippy-toes, or do you think they’ll be scared?

In the event that your kid isn’t already a whiz on the bike, you should consider keeping them on the smaller size, even if they will outgrow it quickly. In this situation, you may wish to consider purchasing a secondhand bicycle (or borrow a bike from a friend). You may purchase a more costly bike some months later, when they have had a growth spurt and are ready to move up to the next size bike.

Buying Guide for Buying a Bike For 7 Years Olds

There are literally hundreds of different brands of children’s bicycles. We don’t have the resources to gather, test, and rank even a portion of them, and we don’t know of anybody who does have the capacity to do so. In addition, most children’s bicycles are offered in shops where you can’t trust the staff to know the difference between coaster brakes and side-pull brakes. They also don’t know much about the quality of the bicycles on the showroom floor, which creates a second issue for the customer. A third issue is that these same workers often build the bikes, despite the fact that they have no official training as bike mechanics. As a result, even a decent bike may be built incorrectly, making any rating questionable. Caveat emptor, in light of the circumstances!

To the best of our ability, we can attempt to educate customers so that they may make better educated decisions about what makes a good bicycle:

Though child bikes are smaller in size, they have the same level of quality in terms of bearings, machining, assembly, finishes, and lightweight as adult bicycles, and they cost approximately the same. However, since children are anticipated to outgrow their bicycles after a year or two, few parents are prepared to invest $300, $600, or $900 on a bicycle for their child to ride. As a result, you won’t often find children’s bicycles of the same high quality as adult bicycles. Consider yourself warned if your child’s bike weights more than yours.


The first step in selecting a bicycle is determining the appropriate size. Unlike adult bicycles, which are measured from the center of the bottom bracket to the top of the seat tube, children’s bicycles are measured by the size of their wheels, which are 12”, 16”, 20”, and 24 inches in diameter. The bicycle should be appropriate for the kid. The rider should be able to dismount and straddle the bike with his or her feet flat on the ground comfortably. When the ability is developed enough, they can ride away with a small tilt of the bike to get their bottom back into their seat and their foot on the pedal. They shouldn’t be riding with their knees pressed on the handlebars, nor should they be stretched out and unable to spin the handlebars freely, either. In contrast to higher speeds when steering is mostly accomplished by leaning, steering with the handlebars is a far more important part of learning to ride for children at slower speeds. If the bike is equipped with training wheels, the handlebars are used to control the whole bike’s steering.


If there is a wide variety of costs available in your child’s size, consider purchasing a pair of bikes at once. It is probable that the heavier bikes will be less expensive. They are most often composed of steel, while the lighter bicycles are constructed from a variety of alloy metals. The only area where the choice of metal may make a major impact, apart from the ease with which the bike can be handled, is in the wheels — a point that we will return to later in the section on brakes.


The next filter has very hazardous designs – remove them from the pool immediately once they are installed. Fortunately, in the United States, the Consumer Product Safety Commission (CPSC) has handled the most of this, and a large portion of the rest of the globe has followed suit, so you are unlikely to encounter any issues. On older bicycles, it is more probable that hazardous characteristics may be discovered. For example, spiky gear change knobs and big bolts were two examples of significant poor design elements from the past that were in the rider’s immediate vicinity — along the top tube or handlebars — and that the rider might impale himself on if they fell forward. Bikes without a derailleur should have chain protectors that are securely attached.


The brakes on a bike are, by far, the most essential mechanical components on the bike. Whatever it was that started the bike going, you want your kid to be in command of bringing it to a complete stop. Typically, coaster brakes (brakes on the rear wheel that are activated by pedaling in reverse) or handbrakes (brakes engaged by a grip on the handlebars that pinches brake pads against the rim of the wheel) are found on children’s bicycles, as well as both. Because of their tiny hands and low hand strength, the coaster brakes on the smallest children’s bikes are necessary. It is recommended that children utilize coaster brakes until their hands are big and strong enough to operate a handbrake properly. A bike with both kinds of brakes is recommended for them to get experience on before moving on to a multi-speed cycle with a derailleur. This will help them become used to hand brakes, since bikes with a derailleur can only be equipped with hand brakes on the back.

Handbrake actuated brakes are available in a number of different designs, with names such as side-pull, center-pull, u-brakes, v-brakes, and cantilever being some of the more popular options. There are both high-quality and low-quality goods available for each design, so you will need to make your own judgment call. Once the braking mechanism has been examined, it is important to make certain that it is rigid and robust enough to support the rider’s weight and speed (the equation mass times velocity equals momentum, mv = p.) If the bike’s only brakes are friction brakes that rub on the wheel rims, alloy wheel rims are the finest choice for it. If your steel rims become wet, they become very hazardous since they have a low coefficient of friction, which means it takes considerably longer to stop your bicycle—which may be extremely deadly!

If the brakes are equipped with brake pads, check certain that the pads are positioned over the rim and that the nuts are securely fastened. It should be possible to contact the drag-end of the brake pad slightly before the lead end if it has been correctly set (in relation to rim movement). This is referred to as “toeing in.” If your brakes squeal when you apply the brakes, this indicates that they are not correctly toed in. On inexpensive bikes and children’s bicycles in general, it may be excruciatingly difficult to make this adjustment without using pliers and gently twisting the brake caliper to get the desired result.


The Consumer Product Safety Commission (CPSC) mandates that the front wheel be equipped with a safety mechanism so that even if the bolts on the axle come loose a long distance, the front wheel will not fall off. In an ideal world, the hub, spokes, and rim would all be made of metal. The wheel should spin easily when you give it a spin if you grip the tire and attempt to wriggle it from side to side while holding the tire.


In most cases, the frames are robust enough to withstand mild misuse and wear. It should be impossible to bend with the hand of an average-sized adult. The frame should be perfectly aligned. It is possible to verify this by standing a few meters in front of or behind the bike and looking to see whether both wheels are in the same plane. Check to see that all of the posts (seat post and handlebar stem) that protrude from the frame are securely fastened together and cannot be bent in any way. A little layer of oil should have been applied to the seat post and handlebar stem before they were built to ensure that they do not freeze up after the first couple of showers. Normally, you won’t be able to verify this until you get home with the bike. After you’ve disassembled them, greased them, and reassembled them, check to see that the bolts are securely fastened.

About Kids’ Bike Sizes  – Overview

When searching for the right bike, one of the first things you’ll notice is the wheel sizes available. Sizes for children’s bicycles are classified according to the diameter of the wheels. Manufacturers then suggest a certain wheel size for a specific age range depending on the typical height of a kid.

You can bet that your child’s first bicycle will be a balance bike, which is just a bicycle without pedals. A balancing bike’s wheels may be as little as 10 inches in diameter or as large as 14 inches in diameter.The tiniest pedal cycles have wheels that are 12 inches in diameter. Youth bicycles feature wheels ranging from 24 to 26 inches in diameter. Bikes with 26-inch wheels and larger are often considered adult-sized, therefore we won’t include them in this page unless they are specifically requested.

The first step in narrowing down your search to a particular wheel size is to establish a budget. Children who are smaller or taller than average may need to be moved to a different age group that is more appropriate for their size.

When it comes to learning to cycle, one of the most important skills for beginners is being able to stop with both feet on the ground securely. You will need to know your child’s inseam measurement in order to determine whether or not they will be able to reach the ground while riding a particular-sized bike.

1)  Measuring Your Child for a Bike

To measure your child, you’ll need the following:

  • Measuring tape.
  • A hardcover book.
  • Pencil.
  • A blank piece of paper.
  • Duct tape.
  • Marker.

2) Measure Their Height

Ask your kid to remove their shoes and stand flat against a wall for a few minutes. After that, take a measurement of their height using the measuring tape. Start from their feet and work your way up to the top of their head, noting down the numbers.

3) Prep Your Wall

There are a variety of methods for measuring your child’s inseam, but we recommend using this one. Remove the cover off an empty sheet of paper and adhere it to the wall using duct tape. Try to get your kid to stand at a height that is about the same as his or her crotch region.

4) Measure The Inseum

To begin, ask your kid to stand against the paper with their feet slightly apart from one another. Placing the hardback book between their legs, with the highest point of the book in their crotch, is a good idea.

Allow your kid to move back, take your pen, and note the spot on the page where the highest point of the book meets the paper surface.

Use the measuring tape to determine the distance between the ground and the mark. This is the length of your child’s inseam.

5) Short Wheelbase vs Long Wheelbase

The wheelbase of the bike is one of the factors that contribute to its overall size. It is the distance between the center of the rear wheel and the center of the front wheel that is referred to as the wheelbase.The longer the wheelbase, the lower the center of gravity, which is excellent for first-time riders who are just getting started. It makes it much simpler for them to achieve and maintain their equilibrium.

It is common for long wheelbases to be associated with lower saddles, which are better suited for young riders. With a long wheelbase, it is simpler to obtain proper arm extensions as well as a somewhat forward-leaning driving posture. If your child’s wheelbase distance is short, make sure their knees do not come into contact with the handlebar as they pedal.

In most cases, manufacturers do not mention the wheelbase in their specifications since it is not often used. If you’re shopping for a bike online, pay attention to the distance between the saddle and the handlebars. If it seems to be tiny, it is probable that the wheelbase is as well.

5) Find A Wheel Size Or Tow

Locate one or two suitable wheel sizes for your kid using the dimensions you’ve gathered. We say two because, even if two bikes have the same wheel size, the saddle and frame may be different between them. Some motorcycles with the same wheel size may have a variation in height of up to 5 inches between them.

Your kid may be able to ride a 12-inch and a 14-inch bicycle. When in doubt, go with the bigger wheel size, provided that the minimum saddle height fits the inseam of your kid.

There will be more space for development as a result, and it will also improve riding stability since bigger wheels are more stable while riding.

Consider the specifications of the bikes you’re considering and do your best to choose one with a saddle height that matches your child’s inseam. If you’re purchasing anything online, read the reviews posted by other parents and caregivers. Many of the postings will provide you with an excellent idea of how the bike will suit you and your riding style.

Is a 20 bike too big for a 6 year old?

A bicycle with a 14-inch wheel will be the most comfortable for your kid if her height is between 34 and 42 inches and her inseam is between 16 and 20 inches. Choose an 18-inch wheel for a bigger 6-year-old who measures 42 to 28 inches in height and has an inseam ranging from 20 to 24 inches in length.

What does a 20 inch bike mean?

The 20″ frame is somewhat bigger than the 16″ frame, and may fit older and taller children than the 16″. In addition to the coaster brake, these bikes may be equipped with hand brakes to assist the kid in learning to slow down or stop using their hands.

Bottom Line

You may find it difficult at times to see your child go to a bigger bike. You want to make sure they feel secure while still pushing them to reach new heights. Finding the finest bike for your kid may undoubtedly be beneficial.

Choosing the correct size is critical; we suggest taking your height and inseam measures rather than your waist measurement since they are more precise. Then look for a bike that has the ability to change the seat height – when selecting, strive for the lowest setting. The rider will have lots of space to develop in this manner.

And don’t forget to snap lots of photos as mementos when they’re out riding their new bike with their friends. You’ll both enjoy looking back on them in the future.
