Are you planning on buying your little one their first bike? It’s hard to find the best one. But, good news, you’re at the right place! 

So, what bike to get? 

As your little munchkin grows, they become more and more adventurous, and getting them a bike that ensures safety allows them to use their imagination, explore around the block and make friends. Any bike for your young tots should be fun to ride but also durable and comfortable too

Biking has so many benefits for your kids, including the following:

  • Strengthens brain and muscles
  • Increases sensory awareness
  • Helps to develop coordination
  • Improves posture
  • Develops focus and concentration skills
  • Encourage self-esteem, confidence, and teamwork 

But due to the high volume of bikes on the market, finding the right one for your kid can take time and effort. You need to consider safety, durability, and adjustable features, so your kid doesn’t quickly outgrow the bike within a few months.  

But don’t let that put you off… 

Before your kids ride a mountain bike, they first have to learn how to use a kiddie starter bike. I have hunted down and reviewed the top bikes for your growing kid to make things easier for you. I have considered features like comfort, durability, and, most importantly, adjustability and safety. Your little one will love the bikes I have picked. 

Stay tuned for my top picks!

Best Bikes for 4-Year Olds

Joystar 12 14 16 inch Kids Bike 

A close up photo of a blue kids bike

Coming in at the number one spot is this incredible bike by Joystar. Joystar offers a range of bikes for 2-9-year-old boys and girls, and they are a renowned brand in the bike industry for kids. And there’s no wonder as to why.  

There’s no better way than to introduce your kids to the world of cycling with Joystar. They offer high-quality bikes that focus on kid-specific geometry and confidence-boosting designs that allow your kid to grow as a rider.  

The Totem comes with a single-speed making it easy for your little one to use. Plus, it comes with coaster brakes which you can operate by turning the pedal backward. It is brilliant when your little one is learning, but I prefer hand brakes, as coaster brakes make the transition much harder.  

As if that was enough…

In terms of the frame, the Joystar uses a durable and robust HI-TEN steel which is tough and elegant; it can survive multiple bumps and abuse from learning to ride a bike and toddler temper tantrums. 

The saddle even comes with a holder, making it easier to help your little one by grabbing it. Plus, the Totem comes with training wheels for some help in the balance department until your little one masters riding on two wheels.

This bike will create the best first, second and hundredth ride for your little one!

  • Easy to maintain
  • Sturdy steel frame
  • Very effective brakes
  • 12-inch wheels for stability
  • The tires could be better.

Woom 2

Suppose your little one is ready to take on their first ‘big boy bike’ and throw out the balance bike, skipping the training wheels and taking on the world. Woom Bikes offer bikes from when your kid is out of diapers to when they’re teenagers! 

But what Woom bike is best for 4-year-olds?

The best bike for your child is either the Woom 2 or Woom 3, depending on the size of your kid. The Woom 2 is ideal for kids three and up to 4 and a half, while the Woom 3 is ideal for ages 3-5 years young kids. It is the seamless transition from balance bikes to pedal bikes. 

Your little one can throw out the balance bike and take on this bad boy. 

Woom 2 is one of the lightest pedal bikes you’ll find on the market, weighing only 12.3 lbs! The bike’s sturdy yet incredibly lightweight aluminum frame is designed geometrically with children aged three and up in mind. 

The low entry point enables young riders to hop on and have a fun ride easily. Your little ones will build their confidence and explore their little world safely. This bike also comes with an innovative braking system to teach your kid to brake without using their feet. 

But wait, get this… 

It comes with a Woom-Designed chain guard that protects the chain and keeps your kid’s hands and legs safe from little pinches and cuts. This chain guard is durable, frictionless, and easy to remove when lubing the chain or changing a flat.

This bike also comes with ergonomic contact points that have been specifically designed for kids; the saddle is designed to meet the anatomy of a young child while the grips are designed for kids’ hands, and the pedals are also durable, reflective, and grippy. 

This bike gives your little one a natural feel and makes transitioning a breeze as they grow. Many parents and I would recommend any bike from Woom, from one to six. You won’t be disappointed!  

  • Ergonomically designed for kids.
  • Super lightweight
  • High-quality air-filled tires
  • Chain guard to prevent pinches and cuts

Well, one customer said, “The bike arrived so quickly, and I was very pleased as it was for my daughter’s 7th birthday. She was so excited. The bike was packaged really and easy to assemble. My only issue was there was a small tear in the bike seat when we unpacked it.” Although there was an issue for this customer, we’re going to assume that it was a delivery-related issue.

Guardian Kids Bikes Ethos

Coming in at number five is an excellent bike by Guardian; it is designed specifically with kids’ safety in mind. The geometry allows your child to be closer to the ground during the extended wheelbase to boost stability. This bike is a real confidence booster. 

These child-specific components make learning to ride a bike safe and fun rather than a chore.

The lightweight design offers more control and stability as they embark on riding new adventures and exploring their neighborhood. The 16-inch wheels make this bike ideal for four and 5-year-olds as they explore while going out with friends around the block.

Safety at an affordable price point? Yes, please! 

Guardian goes through a 34-point safety check during manufacturing, which may seem excessive to some. Still, it ensures that its products are consistently reliable and offer good quality no matter what. 

It also allows them to provide a bike 99% pre-assembled! No more Christmas Eve or Birthday Eve headaches as you scramble to try and assemble the bike before your kid wakes up. All you need to do is put the seat on, handlebars on, and pedals on, and you’re good to go.

One thing I love about Guardian bikes is the SureStop brake system. One brake handle on the proper grip works the rear brake. These brakes are brilliant as it prevents your kid from skidding off and allows them to learn how to use the hand brake effectively.

The chain guard on the front crank also helps errant shoelaces and pant legs from getting snagged, which was a nice touch. The seat is well-made and well-cushioned, making it brilliant for little bums. 

You can’t beat it! Reliable, affordable, and safe. With this cool-looking bike, your kid will be the coolest kid on the block!

  • Sturdy and safe
  • Provides great resistance
  • Too small

Best Bikes 4 Year Olds– A Buyers Guide

When looking for a bike for our kids, we always want to ensure that they have a fun ride while also keeping them super safe. Your kid is probably at the age where they are becoming slightly more adventurous and want to know more about the neighborhood and make friends. 

Your little one is probably eager to start kindergarten, and they want to learn how to ride a bike, so when they make friends at school, they can go on biking playdates. Being 4 is an exciting time for both a parent and a child. 

But there are some key things to look out for when purchasing a bike for your kids; you also need to remember your little one grows quicker than you realize, so getting a bike you can easily adjust is a must for your kid. It is so they don’t quickly outgrow their bike within a few months, and you have to splash out on a new one.  

It is also why I would recommend going for a bike with 16″ wheels rather than 14″ wheels, as 16″ inch wheels are ideal for kids aged 3-5 whereas 14-inch wheels are ideal for kids only 3 and 4 years old, hence why your little one will outgrow it quickly. 

I’m here to make your life as parents a little bit easier and go through everything you need to know before buying a bike for your 4-year-old. 

How To Pick The Right Size For Your 4 Year Old:

Now at the age of four, it can be pretty tricky to decide what size is best for a 4-year-old; if your little one is smaller, should you size down? Or should you stay with the bigger size and convince yourself, “they’ll grow into it.” It’s a constant ongoing debate when we buy anything for our kids. 

It is why adjustability is key; most kid-based brands include adjustability in their products, so the bike grows with the child, and you won’t need to worry too much about getting it to bang on as you can adjust. Hence, the sizing is unique to your child.

To help you out, here’s a rough guide to the age, height, and size of bike you should be looking for:
Wheel Size AgeHeightInseam
12 inches2-32’10 – 3’4″14-17″ or 35-42 cm
14 inches3-43’1 – 3’7″16-20” or 40-50 cm
16 inches4-53’7 – 4’0″18-22” or 45-55 cm
18 inches5-63’9 – 4’3″20-24” or 50-60 cm
20 inches5-84’0 – 4’5″22-25” or 55-63 cm

If you’re wondering, the inseam is the length from the bottom of the ankle to the top of the inner thigh; this helps work out what height the saddle will be when your kid stands over the bike.

However, it would help if you also took these sizing guides with a pinch of salt, as most bikes are adjustable. Some 16 inch bikes can make the seat go as low as 18 inches, while others can go as tall as 21 inches. If you’re worried about the sizing, then before buying online, get your kid fitted in a bike shop.

Hand Brakes Vs. Coaster Brakes: Which One Should You Go For?

You may have seen that my selection ranged between coaster brakes and hand brakes but which one is best? Coaster brakes are commonly found on 16-inch bikes and work when your kid pedals backward.

I’m not too fond of this method, as it can damage your child’s ability to learn to pedal while balancing. Naturally, we pedal backward to regain balance, so pedaling backward and engaging the brake slows the bike down, making it even harder to balance.

Additionally, learning how to use hand brakes is vital as these are the kinds of brakes we use on adult bikes, and teaching your little one to use these brakes makes the transition that much easier.

What To Look Out For When Buying A Bike For Your 4 Year Old?

Size: The first thing you should note is that all the above bikes are available in different sizes. If your kid is between 2-4 years, you should consider a bike with 12-inch wheels.

The 14 inch bike will be the most suitable for 3-5 years old kids or girls who are 36-47 inches tall. For kids aged 4-7 years, you should consider a bike with 16-inch tires. I recommend going for a bike with an adjustable seat post and handlebars so you can adjust as your kid grows.

Bike’s weight:  Bikes are made of different materials; some are heavier than others. When buying, you need to ensure that your kid can handle the bike’s weight comfortably, even when cycling for a long time.

It is one of the key things, and you will find that all the bikes we have reviewed are made of lightweight materials. Steel is the most common bike as it is more affordable and highly durable; however, it can be pretty heavy.

It may be the better option if you see an aluminum frame. However, it may come at a slightly higher price point.

Comfort: Another essential thing you should consider is how comfortable the bike will be for your kid. To make sure that all the bikes are, in fact, the most comfortable, we checked several things, including the seat and handlebars.

Most kid’s brands such as Woom, RoyalBaby, and Joystar use kid-specific geometry to increase comfort for your little one; these are designed around the anatomy of your kid’s body and make reaching points much easier as saddle comfier. 

Style: The bike’s design also greatly matters when choosing a suitable bike for your kid. Kids refer to something stylish or a bike with great colors. If you are searching for a stylish bike for your kid, you can pick any of those we have reviewed because I only picked those with great colors.

Your kid is going to be starting kindergarten soon, if they haven’t already, and they will be making lots of friends around your area, having a stylish bike will help boost their confidence and make them feel like they’re the coolest kid on the block when they go out with their friends. 

Brakes: Your kid’s safety is another key thing you should not ignore. In this regard, you must ensure that the brakes are easy to use and responsive.

One common thing you will find in all the bikes we have reviewed is that they come with reliable coaster brakes. These brakes are the best for bikes for 4 years old tots because they are very responsive and have excellent stopping power.

However, as I said above, these could be better as they promote bad habits during learning and make the learning process slightly harder.

Training wheels: Training wheels are essential if your kid is learning how to ride a bike. They help the kid maintain balance as they learn to break and pedal.

All the above bikes come with adjustable/ removable training wheels, which you can move up a bit when the kid learns how to use the bike correctly.  

I am not a fan of training wheels. Balance bikes are the better transition as it teaches your little one how to balance while learning to ride but if you’ve used a balance bike and looking to have that little safety net, then going for training wheels is ideal.

Safety cycling gears for kids

Cycling is one of the most entertaining activities your kids can enjoy about. It is also dangerous, especially when the kid loses balance when cycling. It means that the kid must always wear safety gears which includes;

Helmet: Bike helmets are typically an unsung hero. It is made of hard shells, which makes them effective in preventing head injuries. However, you must ensure that the one you picked is comfortable for your kid.

You should look for an adjustable kid’s helmet such as the Atphfety Kids Helmet set for 3-8 years, Toddler Helmet. The good thing is that it also comes with knee-elbow pads.

Gloves: Gloves are essential because they enhance grip when the kid is holding the handlebar. ZippyRooz Toddler & Little Kids Bike Gloves for Balance are among the best for kids ages 2-8.

Frequently Asked Questions

Are bikes good for 4-year-olds?

Most parents train their kids to ride a bike starting at a very young age, ages 2-3. It means that a 4-year-old kid can comfortably ride a bike with minimum intervention. The bike should also have training wheels to enhance stability and balance.

Are kid’s bikes expensive?

Bikes for kids come at different prices. However, most of them are very cheap and durable. You also need to compare the features before spending money on any of them.

What size bike is best for a 4-year-old girl?

It’s challenging to say the best size for a young girl; on average, 14-16 inch wheels will be best for a young girl age 4, but it still depends on the height or size of your little girl. If she is slightly smaller than average, then 14-inch wheels may be better, and if she’s slightly taller, then 16-inch wheels will do great.

The same goes for what size you should get for a young boy, age 4. To help, I recommend using the size guide above and comparing it to the size guide of the manufacturer you’re buying from. If you’re still unsure, I recommend getting it sized professionally by your local bike shop.

Final Verdict

A bike is one of the best presents you can give your kid. The look on their face when they open it up on a birthday or Christmas; you can’t beat it. It’s the feeling that makes you feel warm and fuzzy inside as you teach them how to ride their first bike.

If you have been searching for a perfect one, you can pick any of those we have reviewed. The bikes are all affordable, stylish, durable, and safe. They have excellent features, such as a comfortable seat and handlebar, so your kid can use them efficiently.
