Best Bikes for 4 year Olds

1.

Joystar Totem 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 kid’s bike industry, 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, this bike comes with coaster brakes which are operated by turning the pedal backward. This is brilliant for when your little one is learning, but I personally 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 strong 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, so it makes it easier to help your little one by grabbing it. Plus, for a little help in the balance department, the Totem comes with training wheels until your little one masters riding on two wheels.

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

Pros

  • Easy to maintain
  • Sturdy steel frame
  • Very effective brakes
  • 12 inch wheels for stability

Cons

  • Tires are not the best

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 up to when they’re a teenager!

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

Well, the best bike for 4 years old is either the Woom 2 or Woom 3, depending on the size of your kid. The Woom 2 is ideal for kids 3 and up to 4 and a half, while the Woom 3 is ideal for ages 3-5 years. 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 12.3lbs! The frame is geometrically designed with kids three and up in mind with the study yet superlight aluminum frame at the heart of the bike. 

The low entry point and enables young riders to hop on and have a fun ride easily. Your little one 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…

This bike 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 and frictionless while also being easy to remove when lube the chain or change a flat.

The Woom 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, the pedals are also durable, reflective, and grippy. 

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

Pros

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

Cons

  • Little on the pricey side

Latest deal: Woom 2

RoyalBaby Kids Bike

best bike for 4 year old girl

My third pick is by another renowned kids’ bike brand called RoyalBaby; they are experts in kids’ bikes. Their focus on kids’ bikes helps push innovation in kid’s bike designs leading to a better product for younger riders.

This 16-inch wheel is ideal for kids aged 4-5 years and will suit your little boy or girl. This bike comes with training wheels, a water bottle, and a quick-release seat that allows you to adjust according to your kid’s height.

It even comes 65% pre-assembled, which means that you will only need to install the training wheels, handlebars, saddle, and pedals. No more stressful birthday eves or Christmas eves trying to scramble a bike together without waking your little one up. 

And that’s not all.

The frame is strong and made with steel, while some other features included in this bike are a ball bearing drive shaft, a one-piece crank, steel wheels featuring pneumatic rubber, and a chain guard. This is sturdy and made with quality materials to provide a safe riding experience for your kids.

But what did others have to say about this kid’s bike?

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.” So, while there was a drawback for this customer, we’re going to assume this was a problem with the delivery process.

Another happy customer had this to say, though, “Excellent first bike. Sturdy. Bright color but not over the top. Cute. Light. And seems great so far.’ This pedal bike has a 4.5-star rating and over 9,000 reviews on Amazon, so it’s trendy and a perfect first pedal bike for your little ones.

It comes in a range of sizes, from 12-inch wheels to whopping 20-inch wheels, so if you’re looking for a bike for your sibling too, don’t worry, RoyalBaby has you covered. It is a brilliant budget-friendly option, so why not give it a look?

Pros

  • Adjustable training wheels
  • Handlebar pad
  • Stylish design
  • Reliable coaster brakes

Cons

  • A bit heavy

Guardian Kids Bikes Ethos

best bike for 4 year old boy

Coming in at number four 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 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 4 and 5-year-olds as they start exploring 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 the manufacturing process, which may seem excessive for some. Still, it ensures that their 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. There’s 1 brake handle on the right grip that 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 I thought was a nice touch. The seat is well made and well-cushioned, making it brilliant for little bums.

I don’t think you can really beat it! Reliable, affordable, and safe. Your kid will be the coolest kid on the block with this cool-looking bike!

Pros

  • Attractive design
  • Easy to assemble
  • Sturdy and safe
  • Provides great resistance

Cons

  • Too small

Co-op Cycles REV 16 Kids' Bike

best pedal bike for 4 year old

From training wheels to learn how to pedal, these removable bike training wheels are ready to do the distance. Many of you may have already heard about Co-op cycles for their adult bike range, but they do some pretty amazing kid’s bikes too!

Now while I personally prefer balance bikes to get started and build confidence before hittin’ it with the training wheels, training wheels are also brilliant to practice balance and help ease into independent riding with friends around the block. 

Rather than being made with steel like the other frames, I have reviewed (except Woom) Co-op cycles utilize a sturdy lightweight aluminum frame like in their adult range. Aluminum is still as durable as steel, but it is 3x lighter, making it ideal for a little child. 

But that’s not all. 

Your little one will love the sticker pack included with this bike it includes a tonne of letters and fun designs to make your little munchkins bike their own. It also makes a fun afternoon activity if you’re stuck on things to do. 

This bike also comes with coaster brakes which kick in when your kid pedals backward; while this is ideal for learning, my only bone to pick is that it may make the transition from using coaster brakes to hand brakes a little harder. 

But all in all, this is a high-quality product you should expect from REI Co-op Cycles; you and your little one won’t be disappointed! 

Pros

  • Stylish design
  • Comes with removable training wheels
  • Lightweight durable aluminum
  • Comes with a sticker pack for customization

Cons

  • One customer reported that the seat is a little tall

It has revolutionized kids’ learning process, so they become comfortable and confident with feeling the fresh air on their small faces before they get out of their diapers.

The bonus of owning Strider 14 is that the seat can be extended to the height of your child, so it can accommodate around 18 months to 5-year-olds, making it perfect for building your 4-year-olds confidence in riding. It has also been ranked as a best lightweight balance bike that weighs only 3 kg, making it ideal for younglings and siblings. 

But here’s the kicker…

Strider gives full control and makes your child used to responsibility, power, and freedom when it comes to riding. Give your child the childhood of wonder they deserve with their Strider 14 Sport Balance Bike.

Best Bikes 4 Year Olds 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 buying a bike for your 4-year-old; 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, this is so they don’t quickly outgrow their bike within a few months, and you have to splash out on a new one. 

This 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 3-4 years, 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 four years old, it can be quite 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 convincing yourself, “they’ll grow into it.” It’s a constant ongoing debate when we buy anything for our kids.

This 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 bang on as you can adjust. Hence, the sizing is unique to your child.

To help you out, here’s a rough guide of the age, height, and size bike you should be looking for:
Wheel Size  Age Height Inseam
12 inches 2-3 2’10 – 3’4″ 14-17″ or 35-42 cm
14 inches 3-4 3’1 – 3’7″ 16-20” or 40-50 cm
16 inches 4-5 3’7 – 4’0″ 18-22” or 45-55 cm
18 inches 5-6 3’9 – 4’3″ 20-24” or 50-60 cm
20 inches 5-8 4’0 – 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 workout what height the saddle will be when your kid is standing over the bike.

However, you should also take 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? Well, coaster brakes are most commonly found on 16-inch bikes and work when your kid pedals backward. 

Personally, 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 engaging the brake slows the bike down, making it even harder to balance. 

Additionally, learning how to use hand brakes is super important as these are the kinds of brakes are that 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 kids or girls who are 36-47 inches tall. For kids who are 4-7 years, you should consider a bike with 16-inch tires. I would also recommend going for a bike with an adjustable seat post and handlebars so you can adjust as your kid grows.

Bike’s weight:  Kid’s bikes are made of different materials, and 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.

This is one of the key things, and you will find that all the bikes we have reviewed are made of lightweight materials. Steel is most common for kids’ bikes as it is more affordable and extremely durable; however, it can be quite heavy.

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

Comfort: Another important thing you should consider is how comfortable the bike will be for your kid. In this regard, we checked various things like the seat and handlebars to ensure that all the bikes are indeed the best in terms of comfort.

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 well as saddle much comfier. 

Style: The bike’s design also matters a lot when choosing a suitable bike for your 4-year-old 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 outstanding 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: The safety of your kid is another key thing you should not ignore. In this regard, you need to 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 kid’s bikes because they are very responsive, and they also have excellent stopping power.

However, as I said above, these are not ideal as they promote bad habits during learning and make the learning process slightly harder. 

Training wheels: If your kid is in the process of learning how to ride a bike, training wheels are essential. They help the kid to maintain balance as they learn how to break and pedal.

You will find that 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 personally a fan of training wheels. I feel that 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. This means that the kid must always wear safety gears which includes;

Helmet: Bike helmets are made of hard shells, which makes them effective for preventing head injuries. However, you need to ensure that the one you have picked is very comfortable for your kid.

If possible, 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 about it 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 who are between 2-8 years old.

 

Frequently asked Questions

Are bikes good for 4-year-olds?

Most parents train their kids to ride a bike when they are 2-3 years old. This 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?

Kid’s bikes come at different prices. However, most of them are very cheap and durable. You also need to compare the features before you spend your money on any of them.

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

It’s difficult to say the best size for a 4-year-old girl; on average, 14-16 inch wheels will be best for a 4-year-old girl, 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 4-year old boy. To help, I would recommend using the size guide above and compare it to the size guide of the manufacturer you’re buying from. If you’re still unsure, I would recommend getting sized professionally by your local bike shop.

Final Verdict

A bike is one of the best presents you can give your kid, a 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 all warm and fuzzy inside as you teach them how to ride their very first bike.
