How to Choose a Bike for 6- to 8-Year-Olds
Picking the Right Size
When we talk about bike sizes, we mean wheel diameter. For most 6- to 8-year-olds, 18- to 20-inch wheels are the sweet spot.
If your child is tall or nearing 9, a 24-inch might work. However, always check height and inseam rather than relying on age. Seat heights vary wildly between brands.
To get the right fit, measure their inseam. Tape a piece of paper to the wall, place a book between their legs (crotch level), and mark the top of the book. Measure from the floor to that mark.
Choose a bike with a seat height 2 to 3 inches higher than that inseam measurement. At this age, your child should have a slight bend in the knee when seated with feet on the ground.
Adjustable Components
Kids grow fast, so look for a bike that grows with them. Adjustability is key to getting more bang for your buck.
Check how much the seat and handlebars can move. Some seats raise up to 6 inches, which adds years of use. Always buy a bike where your child fits the lowest setting comfortably so they have room to grow into it.
Watch The Tippy Toes
Bike Geometry
Frame design dictates how the bike feels. Leisure bikes, often called cruisers, put kids in an upright position. These are great for beginners and casual neighborhood rides.
Sportier bikes, like BMX or mountain bikes, use an “aggressive” position where the rider leans forward. This helps with turning, speed, and balance, but it suits experienced riders better.
Hybrid options exist, too. These sit somewhere in the middle and are excellent for kids who want to try different riding styles without committing to a pro-level bike.
Proper Brakes
Most 6- to 8-year-olds have the coordination for hand brakes, but many bikes in this size range include both a hand lever and a coaster (pedal) brake (1).
There is some debate here. Some parents worry pedal brakes throw off balance, while others think small hands struggle with hand levers. In our experience, kids adapt quickly to either.
Some brands, like Guardian Bikes, use a single-lever system that controls both wheels, simplifying the process for learning minds.
Weight
A lighter bike is easier to control. Ideally, the bike should weigh about 30% less than your child.
Once you step up to 20-inch bikes, things get heavier due to gears and shocks. Aluminum frames are your friend here, as they cut down weight significantly compared to steel. If the bike is too heavy, your child will tire out faster and struggle to maneuver.
Gears
This is the age where gears become an option. Before this, single-speed is standard because little kids don’t need the complexity.
Gears are great for hills, but they add weight and maintenance. If you live in a flat area, single-speed is fine. If you have hills, gears help, but be prepared to teach your child when and how to shift. It might take some practice.
Appropriate Tires
Where will they ride? Tire tread matters.
- Pavement: Smooth or foam-filled tires work best for street cruising. They roll fast and quiet.
- Dirt/Gravel: Look for knobby, textured tires. Deep treads provide grip and prevent slips on loose ground.
You can always swap tires later if your child’s interests change from sidewalk surfing to trail blazing.

Raleigh Bikes Jazzi 20-Inch
Best Lightweight Bike for 6- to 8-Year-Olds
The Raleigh Jazzi 20-inch is a featherweight champion. Weighing just 21.6 pounds, it is significantly lighter than many competitors, making it easier for kids to handle.
Standout features include alloy V-brakes and a rear coaster brake for double the stopping power. It fits kids aged 4 to 8, specifically those between 44 and 52 inches tall.
The geometry puts the rider in a slightly aggressive, forward-leaning stance. If your kid loves speed or racing around a track, this form is ideal. Plus, the smooth tires let them glide effortlessly on neighborhood pavement.
What We Like
Excellent Weight
Weight matters for small riders. The Jazzi’s low-standover aluminum frame gives kids full command of the bike. Accelerating, cornering, and stopping feel effortless, even for petite riders.
Aggressive Geometry
Raleigh designed this for action. The forward-leaning position helps kids make sharp turns and tackle small jumps with confidence. It is a step up from basic cruisers.
Versatile Tires
While smooth enough for pavement, the tires and durable alloy rims can handle packed dirt paths. They offer good traction without slowing the rider down on asphalt.
What We Don't Like
Brakes Feel Flimsy
While it has V-brakes, some parents felt they were a bit flimsy compared to higher-end mountain bikes. You might need to adjust them out of the box for the best grip.

Dynacraft Magna Major Damage Dirt Bike
Best Dirt Bike
This BMX-style dirt bike is an epic choice for tearing up the neighborhood or hitting local trails. It is built for beginners aged four to eight.
It comes with training wheels, perfect for mastering balance. Once your child gains confidence, whip them off for a full two-wheel experience.
We also love the high-vis yellow paint job. It looks cool, but more importantly, it makes your child highly visible to cars on the street.
What We Like
Reliable Coaster Brakes
When your child is flying down a trail, they need to stop fast. The coaster brakes are intuitive and reliable, ensuring smooth, safe stops without hand strength requirements.
Safety Padding
The handlebar features a stylish padded crossbar. It looks pro, but it also protects your child’s face and chest if they lean forward too fast or stop suddenly.
Easy Assembly
Kids hate waiting. Thankfully, this bike is straightforward to build. Most parents report getting it road-ready in under 30 minutes.
What We Don't Like
Limited Growth Room
This bike fits kids around 43 to 48 inches tall best. Since the frame is compact, they might outgrow it in a year or so.
Stiff Pedals
Some units come with tight pedals that can be hard for smaller kids to turn. You might need to grease them or work them in before the first big ride.

Best 20-Inch Kids’ Bike for Girls
The Firmstrong Bella Classic Cruiser is all about laid-back vibes. With its relaxed geometry, it is perfect for growing girls cruising the boardwalk or cul-de-sac. It fits riders from 3 feet, 2 inches up to 4 feet, 4 inches tall.
This is a single-speed bike, meaning no complicated gears to confuse new riders. It’s designed for comfort, not racing.
The classic white-wall balloon tires provide natural suspension, smoothing out bumps. Plus, the mint green retro look is a total head-turner. Braking is handled by a simple coaster brake, making stops easy and intuitive.
What We Like
Effortless Cruising
No cables, no shifters, no fuss. This bike lets your girl focus on the joy of riding. The single gear maintains a steady pace, perfect for social rides with friends.
Comfort First

Mongoose Legion Sidewalk Freestyle BMX 20-Inch
Best Introduction to BMX Riding
BMX bikes can be intimidating, but the Mongoose Legion blends pro features with sidewalk-friendly sizing. It fits riders between 4 and 5 feet tall.
Built with a hi-tensile steel frame, this bike is tough enough for aggressive riding and beginner tricks. The 2.3-inch tires offer stability, while aluminum rims keep the weight manageable.
Steering is sharp thanks to the threaded headset and 48mm stem. The one-piece crank makes pedaling efficient, allowing your child to build speed quickly for jumps or races.
What We Like
Built to Last
The steel construction is durable enough for rough play but sleek enough for street riding. It is a sturdy machine that can easily be passed down to younger siblings.
Precision Control
BMX riding requires good brakes. The steel U-brake offers precise speed control, which is safer than standard caliper brakes for tricks. The steering is responsive, giving kids confidence on turns.
Grippy Tires
The wide BMX tires stick to the ground, whether on pavement or dirt. They provide excellent stability for kids learning to maneuver off-road.
What We Don't Like
Needs Tuning
Out of the box, parts like the chain and bearings might be too tight. You may need to loosen and adjust them.
Brake Adjustments
Some parents found the brakes ineffective initially. Usually, this just requires tightening the cable tension during assembly.

Royalbaby Space Shuttle 18-Inch Bike
Best 18-Inch Bike for Boys
For active boys aged 5 to 7, the Royalbaby Space Shuttle is a futuristic ride. It uses a unique magnesium alloy frame, making it lightweight and cool to look at.
The frame is hollow and cast as one piece, eliminating ugly welds and weak points. It features a reliable single-speed drivetrain and disc brakes for superior stopping power.
With 2.4-inch wide tires, this bike handles off-road bumps easily. The futuristic design helps kids feel like they are piloting a rocket, not just riding a bike.
What We Like
Magnesium Frame
Instead of steel, this bike uses magnesium alloy. It is lighter than steel but incredibly strong. At roughly 21 pounds, it is manageable for small kids to maneuver.
Stable Ride
The wide tires and shock-absorbing frame material make for a smooth ride. It feels planted on the ground, reducing the wobble factor for kids transitioning from training wheels.
Sleek Looks
The molded frame allows for curves and lines you can’t get with standard tubing. Available in white, purple, and black, it looks like a high-end sports bike.
What We Don't Like
Stiff Brake Levers
The disc brakes are powerful, but the hand lever can be stiff for very small hands. Your child might need some grip strength practice.

Best 20-Inch Kids’ Sports Bike
The Royalbaby Freestyle is a versatile sports bike designed for action. With 20-inch wheels and deep-tread tires, it grips the road and dirt equally well.
It comes equipped with a kickstand and a dual braking system, a front caliper hand brake and a rear coaster brake. This redundancy is great for safety.
Assembly is a breeze. Royalbaby includes all the necessary tools, plus fun extras like a bell and a water bottle holder. The quick-release seat makes height adjustments instant.
What We Like
All-Terrain Ready
The wide, knobby tires give this bike SUV-like capability. Whether your kid rides on grass, gravel, or pavement, the Freestyle handles it.
Double Safety
We love the dual brake setup. The hand brake teaches them how to use levers for fine control, while the coaster brake acts as a fail-safe for panic stops.
Bonus Goodies
It is rare to get accessories in the box. The included bell, water bottle, and kickstand add immediate value and fun for the rider.

The bike arrives 95% assembled. You just need to attach the handlebars, pedals, and seat. The instructions are clear, and tools are included.
What We Don't Like

Schwinn Elm Girls 18-Inch Bike
Best 18-Inch Bike for Girls
For girls not quite ready for a 20-inch frame, the 18-inch Schwinn Elm is a perfect middle ground. It is less intimidating than bigger bikes but still feels “grown-up.”
The design focuses on fun and safety. It features a front basket for toys, a full chain guard to keep pants clean, and a mix of hand and coaster brakes.
The adjustable seat fits girls between 42 and 52 inches tall. The frame geometry is specifically designed to be easier for kids to mount and pedal.
What We Like
Smart Start Geometry
Schwinn’s “Smart Start” design isn’t just marketing, it works. The pedals are closer together to match a child’s hip width, and the seat is positioned to improve leverage. This makes pedaling easier and wobble-free.
Cute & Functional
The aesthetics are spot on, with vibrant colors and matching rims. The front basket is a huge hit with kids who want to bring a stuffed animal along for the ride.
Hybrid Braking
Like the Royalbaby, this bike has both coaster and hand brakes. It allows your child to transition to hand brakes at their own pace without losing the safety net of the pedal brake.
What We Don't Like
Plastic Basket
The basket is cute but made of thin plastic. Don’t expect it to hold heavy items; it is mostly for show or light toys.
Assembly Tricky
Some parents noted a lack of clear instructions in the box. You might need to check YouTube for a guide if you get stuck.

FAQs
What Bike is Suitable For a 6-Year-Old?
Most 6-year-olds fit best on a bike with 18-inch or 20-inch wheels. Focus on inseam height rather than age. They should be able to touch the ground with the balls of their feet while seated.
Should Kids’ Bikes Have Suspension?
Probably not. Cheap suspension adds weight without much benefit. Unless your child is riding serious mountain trails, a rigid fork is lighter and easier to control. Wide tires provide plenty of cushioning for sidewalks.
How Do I Know If My Bike is Too Big For My Child?
If they wobble excessively, can’t touch the ground when seated, or have to stretch their arms fully to reach the handlebars, it is too big. A bike that is too large is dangerous and hard to stop.
How Long Does it Take a 6-Year-Old to Learn to Ride a Bike?
It varies. Some kids learn in an afternoon; others take weeks. Balance bikes speed up the process. Be patient, keep sessions short, and focus on fun rather than pressure.
At What Age Should Training Wheels Come Off?
Ideally, between ages 4 and 6. However, every child is different. If your 8-year-old still needs them, that is okay too. The goal is confidence. Once they can coast with feet up, they are ready to ditch the training wheels.
Are Coaster Brakes Safer Than Hand Brakes?
For beginners, coaster brakes (pedaling backward) are often safer because they are intuitive and rely on leg strength. However, hand brakes are standard on adult bikes, so learning to use them early is a great skill. Many 20-inch bikes include both systems for maximum safety.
