The Best Bikes for 6- to 8-Year-Olds of 2024

Here are the top seven bikes for 6- to 8-year-olds on the market.

Raleigh Bikes Jazzi 20-Inch

Best Lightweight Bike for 6- to 8-Year-Olds

The Jazzi 20-inch bike from Raleigh is built with lightweight materials. It’s amazingly light when compared to other bicycles from Raleigh, weighing in at 21.6 pounds.

Some of the outstanding features included are the alloy V-brake and rear coaster. The bike is suitable for children aged 4 to 8, with heights ranging between 44 and 52 inches.

The geometry of the bike puts the rider in an aggressive position. If your kid loves to go fast or race around a track, this is the form to look for. With the smooth tires, your child can glide across the roads in your neighborhood.

What We Like

Excellent Weight

Although weight isn’t a huge factor for this age group, a lightweight bike is still preferable. Jazzi is incredibly light, built with a low-standover aluminum frame, giving the rider full control. Building speed, turning, and stopping is a breeze, even for the smallest user.

Aggressive Geometry

When designing the Jazzi bike, Raleigh clearly intended it for more than just leisure use. With the aggressive position, your child leans slightly more forward than on other bikes. It’s optimal for making sharp turns, going fast, or tackling a jump.

Traction Tires

With the bike’s smooth tires, navigating various terrains is a breeze. They provide ample traction for simple dirt roads. The rims are durable, made of alloy, and capable of taking on a few jumps.

What We Don't Like

Brakes Are Flimsy

The Jazzi bike features alloy V brakes, but some parents weren’t impressed. A few said they were flimsy and weren’t as efficient as they’d hoped they would be.

User Experience

Best bike for my 4-year-old granddaughter, this bike is not only easy to assemble but also boasts a high-quality build and a gender-neutral green color. However, I had to spend an hour adjusting the overly tight wheel bearings, chain, and headset to prevent potential damage. Although the Raleigh logo is present, the bike is made in China and arrived without retaining clips for the front wheel and assembly instructions - I had to order the clips separately and search for a similar bike's assembly video. Despite its few drawbacks, this bike is a great size for my little one, and with some upgrades and regular maintenance, it'll handle anything she can throw at it.

Dynacraft Magna Major Damage Dirt Bike

Best Dirt Bike

This BMX dirt bike is an epic way for your little one to ride around your neighborhood, the park, or bike trails. It’s ideal for beginners and can be ridden by kids between four and eight years old.

It comes with training wheels so they can learn how to balance and stabilize themselves on the bike. Once they grow in confidence, you can easily adjust or remove these to give your child a bit more independence on the bike.

We also love the bright yellow fashion of this bike, meaning it’s highly visible. This is perfect for riding around neighborhoods so cars are aware of the bike.

What We Like

Coaster Brakes

When your child is flying through the trails on their bike and suddenly needs to stop, they’ll be super grateful for the coaster brakes. These brakes mean stopping is smooth, steady, and safe.

Padded Handlebar

The handlebar is padded in a super vibrant and stylish design. This makes the bike look epic, so your little one can ride in style. But it also means there is extra safety in case they lean on the handles a little bit as they’re stopping the bike.

Easy Assembly

When this arrives, your child will be eager to get on it right away for a test ride. Thankfully, assembly is straightforward and generally takes less than 30 minutes.

What We Don't Like

Not a Lot of Growing Room

This bike is best suited for kids around 43 to 48 inches tall. That means there isn’t a lot of growing room. Most customers say this bike lasted for around one year before they had to upgrade to a bigger size. The seat is adjustable, but it still doesn’t help too much.

Tight Pedals

The pedals on this bike are pretty tight. It makes it quite difficult for younger kids to pedal. Keep that in mind when buying; it’s best for kids with a bit of strength behind them!

Personal Perspective

I'm happy with the overall look and sturdiness of this bike, but assembly proved to be quite challenging due to some parts not fitting well together. My son was initially disappointed that he couldn't ride his new bike right away, as we had to tighten everything that was preassembled and even order a missing seat post clamp. Despite the initial hurdles, my son loves riding this bike now and it seems well-crafted to withstand his growth and daily adventures.

Firmstrong 20-Inch Bella Classic Cruiser Bike

Best 20-Inch Kids’ Bike for Girls

With a laid-back geometry, the Bella Classic Cruiser from Firmstrong is a good pick for growing girls. It’s a 20-inch bike built for cruising around town or going to the beach with friends. The cruiser is suitable for kids measuring 3 feet, 2 inches to 4 feet, 4 inches tall.

Due to the laid-back position, it’s an excellent introduction to leisure riding. It’s a one-speed bike — for the relaxed biking this was designed for, there’s no need for gears.

The bike sports classic white-wall balloon tires, so the ride is cushioned and smooth. Girls will love the look. It’s mint green and retro-inspired, but it’s also available in other colors. When the ride is over, your girl can come to a soft stop using the coaster brakes.

What We Like

Leisure Riding at Its Best

Without disturbing cables or complicated handles to twist, this bike lets your girl cruise how she likes. The smooth balloon tires make the ride soft by adding some suspension, and the single gear allows the rider to maintain a steady speed. It’s all about sitting back and enjoying the surroundings with her friends.

Wide Tires and Comfy Saddle

With wide tires, the cruiser is stable and comfy to ride. Aiding that is the broad saddle and extra cushioning. The seat also features a dual-spring system, which helps to even out bumps in the road.

Braking Made Easy

Once your girl has mastered pedaling, she’s ready for coaster brakes. When riding the cruiser, all the rider needs to do is pedal backward, and the bike comes to a soft stop.

Fashionable Design

Cruiser bikes often have an old-school look to them, and this one from Firmstrong is no different. With the white-wall, wide tires, the retro vibes are through the roof. It’s intriguing to look at with the unique frame and wide handlebars.

What We Don't Like

Community Feedback

I'm pleased with the look of this bike and my daughter says it feels sturdy with a smooth ride. However, it did arrive with missing hardware for the front fender, requiring me to purchase extra nuts and bolts. Additionally, there was a tear in the seat and a bent head tube entry for the handlebars, which I had to fix myself. Despite these issues, my daughter and granddaughter both enjoy riding the bike in their neighborhood and at the beach.

Mongoose Legion Sidewalk Freestyle BMX 20-Inch

Best Introduction to BMX Riding

BMX-style bikes are not so newbie-friendly, but if you mix them with a sidewalk cruiser, you have a winner. The Legion Mag is a great introduction to BMX riding. It’s a 20-inch bike suitable for children between 4 to 5 feet tall.

With a hi-tensile steel frame and a 20.43-inch tube length, the Legion Freestyle is durable and excellent for aggressive riding. The 2.3-inch-wide tires add ample stability, and the aluminum wall rims prevent the bike from being too heavy.

Your child will love riding this bike — it’s smooth to turn and easy to build up speed. A threaded headset with a 48-millimeter stem connecting the handlebar and fork enhances the steering. The drivetrain features a 170-millimeter, one-piece crank, making it easy to go fast.

What We Like

Outstanding Durability

With a hi-tensile construction, it’s the perfect combo for quiet neighborhood riding while still being sturdy enough to go on the trail. The bike will grow with your child and may even become a hand-me-down.

High Precision Brakes and Steering

BMX riding is all about control, and the brakes play an important role. The Mag features a steel U-brake. These are perfect for high-precision speed control and ultimate brake capacity.

The threaded headset offers a superb steering performance. Whether your kiddo rides on the pavement or trails, they’ve got full control.

BMX Tires

The bike features BMX-style tires with aluminum rims and optimal grips, so going off-road or doing tricks is a breeze. The wide design optimizes the rider’s stability.

What We Don't Like

Requires Adjustments

Out of the box, a few parents noted many parts, including the chain, bracket, and steerer tube bearings, were too tight and required a fair amount of adjusting.

Many reviewers complained about the brakes, saying they’re useless. Some parents said the issue was that the brakes were too loose upon arrival, and a quick tightening mended the problem.

First-Hand Impression

From my experience, this BMX-style sidewalk cruiser, the Legion Mag, is perfect for kids who want a thrilling introduction to BMX riding. As a 20-inch bike suitable for children between 4 to 5 feet tall, it boasts a hi-tensile steel frame and a 20.3-inch tube length, making it durable for aggressive riding while the 2.4-inch wide tires provide ample stability. The aluminum wall rims prevent the bike from being too heavy, and my child found it smooth to turn and easy to build up speed. The steering is enhanced by a threaded headset with a 48-millimeter stem connecting the handlebar and fork, and the drivetrain features a 170-millimeter, one-piece crank for an effortless ride. However, it requires some adjustments, but once done, it delivers outstanding durability, high precision brakes, and steering.

Royalbaby Space Shuttle 18-Inch Bike

Best 18-Inch Bike for Boys

For active boys between the ages of 5 and 7, we’ve chosen this bike from Royalbaby. It’s the ultra-light, magnesium alloy Space Shuttle bicycle — ready for boys who love speed.

This bike is uniquely built. The frame is in one piece, meaning there are no welded parts, making it more durable. It also features a sturdy single-speed drivetrain.

The Space Shuttle works well for going off-road. It’s suited with 2.4-inch-wide tires that are textured to provide extra grip.

Everything about the bike works to stabilize the ride. It can help your child feel more confident by making the experience less intimidating.

What We Like

Ultra-Light

As opposed to using the usual aluminum or steel, Royalbaby used magnesium alloy for the Space Shuttle. It’s incredibly light, weighing roughly 21 pounds, yet highly durable.

The Space Shuttle is great for building speed. The lightness of the frame makes it easy for even the smallest child to pedal while still having full control.

Superb Stability

A great benefit of using magnesium alloy, besides the lightness, is its anti-impact elements. You have to be rough to make it budge. This translates to its riding performance, giving it superb stability.

Your kiddo can safely bring it onto the rough off-trail roads. The frame and the wide tires reduce the risk of falling.

Color Options Available

The Space Shuttle is available in three colors: white, purple, and black. The design is appealing to children of all ages.

The magnesium alloy has another benefit. It’s easy to form and mold, adding clean lines to the bike and eye-catching shapes.

What We Don't Like

Hard Hand Brake

While most reviewers are happy with the bike, some said there was an issue with the hand brake. It’s tough for a child to use correctly, which compromises their stopping time.

Royalbaby Freestyle Kids 20-Inch Bike

Best 20-Inch Kids’ Sports Bike

If your child enjoys biking sports, then the Freestyle from Royalbaby is well worth a look. With 20-inch-wide, deep-treaded wheels, it’s perfect for activities — on or off-road.

The bike is available in various sizes, down to 12-inch wheels, each variant featuring specific components. The 20-inch bike comes with a kickstand and dual brakes — one caliper and a coaster brake.

It’s easy to assemble the bike. Everything you need is in the package, along with additional features such as a bell, water bottle, and tools for the assembly. The seat adjusts with ease using the quick-release system.

What We Like

Superb Sports Bike

With large, wide tires and durable wheels, the Freestyle is great for bike sports. The rider can take it around the track, do stunts at the park, or race around the neighborhood.

Dual Brakes

Having full control of the speed is essential when doing biking sports, and the Freestyle includes two brakes. On the handlebars, there sits a lever to control the front wheel brake. This is ideal for fine adjustments while doing tricks.

Then the coaster brake helps to come to a smooth full stop. It will also prevent those dreadful head-over-handlebar accidents.

Easy Assembly

Everything you need is ready in the box. Tools and an owner’s manual are in the bundle — the instructions are easy to follow. There may not be much to do to get it on the road — many reviewers said the bike comes mostly assembled.

What We Don't Like

Considerably Heavy

This 31-pound bike is pretty heavy for a child’s bike. It can be heavy to lift, even for an adult.

Schwinn Elm Girls 18-Inch Bike

Best 18-Inch Bike for Girls

For 6- to 8-year-olds, 18-inch bikes like this one are the perfect size. They’re a bit smaller and less intimidating than a 20-inch bike while still featuring most of the “big-kid” components.

With child-friendly colors and features, your girl should love cruising around on the Elm Girl’s bike. It includes a cute front basket, a combination of coaster and hand brakes, and a full chain guard to protect her legs.

An adjustable seat ensures the bike can accommodate growing girls who are between 42 and 52 inches tall. It has a slack-tube angle for easy mounting and includes optional training wheels.

What We Like

More Stability

The main highlight of the Elm Girl’s bike is the Smart Start design. It consists of a sturdy steel frame with child-specific proportions, making pedaling and steering easier. Moreover, the construction optimizes stability, minimizing wobbling while riding and helping the cyclist’s confidence.

Fun Features

The Elm bike is fun to look at with a superb child-friendly appearance. It sports vibrant colors — every element is coated, even the rims. At the front, your girl has a matching basket for carrying her stuff around.

Child-Friendly Proportions

Schwinn strives to make your child feel comfortable and confident while riding the bike by optimizing the proportions. Everything from the handle’s diameter to the distance between the pedals provides the perfect balance for small riders.

What We Don't Like

Fragile Basket

It’s made of plastic and can’t take rough handling or heavy cargo. A few parents said they exchanged it for a more durable alternative.

No Instructions

Unless you’re a bike expert or at least have some experience, you’ll have a hard time putting this together. It doesn’t come with instructions, so reviewers said they went to bike shops or viewed online videos for assembly guidance.

Community Feedback

I recently purchased this bike for my child and was pleasantly surprised by the fast delivery and well-protected packaging. The assembly process was straightforward, thanks to the easy-to-follow instruction book. However, I was disappointed with the plastic hand brake handlebar mounts and adjusters that stripped out during adjustment. Additionally, both front and rear tire rims were warped, causing concerns for safety and premature wear. Despite these drawbacks, my child loves the bike, and its vibrant colors and overall design are quite appealing.

How to Choose a Bike for 6- to 8-Year-Olds

Picking the Right Size

When talking about bike sizes, we’re referring to the diameter of the wheels. For children who are 6 to 8 years old, the best sizes are anything from 18- to 20-inch bikes.

If your child is taller or about to turn 9, you could go for a 24-inch. However, pay close attention to your child’s height and inseam measurements — age isn’t always the best guide. The seat height varies between brands. Some are high, even on the lowest setting, while others remain on the shorter side.

To find their inseam size, attach a piece of paper to a wall using duct tape. Place a book between the child’s legs in the crotch area. Mark the paper at the tallest point of the book.

Measure from the mark to the floor, and you have their approximate inseam. This is where it may get confusing, so stay with us. Once you’ve decided on an 18- or 20-inch wheel size, focus on the seat height of the bike you’re looking at.

Go for a seat height that’s 2 to 3 inches higher than the inseam. For this age, your child should have a slight bend of the knee while seated and resting their feet on the ground.

Adjustable

Another helpful feature to look for is adjustability. Having a bike that allows for alterations will enable your child to use it longer.

How much the bike can adjust varies between brands. Ensure there’s ample room for growth. Some seats can be raised as much as 6 inches or more. This makes a significant difference, potentially adding years of use.

Always aim for the lowest height setting when buying; otherwise, your child will outgrow it faster.

Watch The Tippy Toes

For this bike size and age group, the rider should have their toes just touching the ground while seated. This helps them achieve maximum efficiency when pedaling. If your child is still learning, perhaps lower the seat so both feet can fully touch the ground.

Bike’s Geometry

With 18- and 20-inch bikes, the frame design varies depending on the primary purpose of the bike. Some are constructed for leisure riding — these are called cruisers and promote an upright position, ideal for beginners.

Other manufacturers focus on sports bikes, like BMX or mountain biking. These promote what we call an aggressive position where the rider sits forward-leaning.

This stance assists them with turning, building speed, and balancing. These bikes are more suited to experienced riders.

Other bikes come somewhere in between, enabling the rider to use them for different activities but not to an exacting standard. This is an excellent option if your child is still learning.

Proper Brakes

At this age, most children are coordinated and strong enough to handle both a hand brake and a coaster brake. The manufacturer has a requirement to include both types on this bike size (1).

There are conflicting views on which type of brake is best for young riders. Some think it’s best to avoid a foot-controlled brake as it may throw your child off balance.

Others state coaster brakes are best as small hands have a hard time activating a hand brake. Either way, once your child is comfortable and confident when riding, they can easily handle both.

Some advanced companies like Guardian Bikes utilize a single-lever braking system. This is a design where one lever controls both the front and rear wheels.

Weight

Your child’s bike should weigh 30% less than their body weight. A lighter bicycle means better control and more comfortable pedaling, which children need.

Once in the 20-inch bike market, the bicycles become considerably heavier due to added features such as shocks and gears. As long as your kiddo can handle it, it’s okay.

Gears

Another first on bikes for this age range is the option for gears. Up until this point, gears were non-existent as small kids don’t need them, and they’re complicated to use.

Gears are still optional, though — not all manufacturers include them until the 24-inch sizes. Whether you should choose gears depends on your child. Many around this age are still not able to use them properly.

Knowing when to switch gears can be challenging for a 6-year-old. They may do it randomly in the beginning, but soon they’ll learn.

Appropriate Tires

The terrain your child will be riding on should impact what type of tires to look for. Do you live in the countryside surrounded by dirt roads or in a suburban neighborhood with flat roads? If your youngster merely cruises around your street, smooth tires, perhaps even foam-filled ones, will do.

When riding on rough terrains such as dirt or gravel, the tires should be durable. For grip, deeply treaded tires are best — these are textured and ensure superb traction.

Should your child’s interest change, you can always switch the tires out. Many parents admit to doing this if their kids weren’t happy.


FAQs

What Bike is Suitable For a 6-Year-Old?

For a six-year-old, a bike with 16 to 20-inch wheels is typically suitable. The key is ensuring the child can comfortably reach the ground with their feet while seated and easily handle the bike.

Should Kids’ Bikes Have Suspension?

Suspension on kids’ bikes isn’t usually necessary unless they’re riding on very rough terrain. For typical neighborhood riding, a simpler bike without suspension often works better and is lighter and less complicated for a child to handle.

How Do I Know If My Bike is Too Big For My Child?

If your child struggles to get on and off the bike, can’t touch the ground with their feet when seated, or has difficulty reaching the handlebars, the bike might be too big. A properly sized bike is crucial for safety and comfort.

How Long Does it Take a 6-Year-Old to Learn to Ride a Bike?

The time it takes for a six-year-old to learn to ride a bike varies greatly. Some kids pick it up in a single afternoon, while others might need a few weeks of practice. It depends on their coordination, confidence, and previous experience with balance bikes or tricycles.

At What Age Should Training Wheels Come Off?

Training wheels can usually come off between ages four and eight, depending on the child’s readiness and comfort level. The key is to remove them when the child feels confident and can balance on their own.
