How to Choose a Bike for a 3 to 6 Year Old Child

Bike Sizing

Learning to ride a bike is a rite of passage for many children. It's a fun and healthy activity that can provide years of enjoyment as they grow. But with so many different bikes on the market, it can be tough to know where to start.   

Below we'll look at what to think about when choosing the right bike for a 3 to 6 year old. At Bike Club, whether you need balance bikes for 4 year olds or pedal bikes for 3 year olds we have you covered.  

Bike Size  

The most important factor to consider when choosing a bike for a 3 to 6-year-old child is size. For most children between 3 and 6, a balance bike or a first pedal bike is the best choice. You need to make sure you get one that fits your child, however. The right bike size for a 5 year old can sometimes be the same as for some 3 year olds.   

We believe the best way to get a bike that fits like a glove is to use inside leg measurement. You can take a look at our sizing guide for more information 

Once you have your child’s inside leg measurement, you can input it into our Interactive Bike Finder 


A lightweight bike is important for a 3 to 6-year-old child because it will be easier for them to handle. A heavier bike will be more difficult for them to pedal and manoeuvre, which can make it frustrating and even dangerous.  

Here are some additional benefits of a lightweight bike for a 3 to 6-year-old child:  

  • It’s easier for you to carry the bike when they are not riding it.  
  • It will be easier for them to lift the bike over obstacles.  
  • It will be easier to pedal the bike up hills.

Seat Height & Adjustability  

When choosing a bike for a child, be on the lookout for seat height and adjustability.  

This allows you to customise the bike's fit to suit your child's specific height and leg length.  

As children grow rapidly, an adjustable seat also enables you to adapt the bike as they get taller, until they need a new bike entirely.   

Frame Design   

Choosing a lightweight frame specifically designed for small children is essential. Firstly, it enables children to manoeuvre the bike more easily, which will give a boost to their control and confidence while riding.   

It also reduces the strain on their muscles, allowing for longer and more enjoyable rides. A frame designed for kids takes into account their smaller stature and proportions, providing easy reach to the handlebars and pedals.   

Stabilisers or Balance Bikes  

The great debate, stabilisers of balance bikes? Traditionally children have learnt on regular bikes with stabilisers, but the tide is turning with the popularity of balance bikes.  

At Bike Club we are firmly in the balance bike camp for a number of reasons:  

  • Development of balance and coordination: Balance bikes allow children to develop their balance and coordination skills naturally.    
  • Easy transition to pedal bikes: Using a balance bike helps children develop a sense of confidence and control over their movements. This makes the transition to a pedal bike much smoother.   
  • Focus on core biking skills: They allow children to focus solely on the core biking skills, such as steering and manoeuvring. 
  • Enhanced safety: Balance bikes are closer to the ground, providing a lower center of gravity. This makes it easier for children to stabilise themselves.  


At this age range some balance bikes will have brakes and some are designed without them. Pedal bikes however will always have at least one brake.    

For young children, a balance bike without a brake is still perfectly safe. They will have one less thing to worry about and be able to use their feet to come to a stop. Having a brake however does have the advantage of getting them used to using one for when they transition to a pedal bike.

Safety Features  

The balance bikes we stock all come with steering limiters for safety. These limiters are designed to restrict the range of the handlebar's turning radius. This encourages more gradual and controlled steering movements and prevents sharp turns.   

Some of our first pedal bikes like Woom 2 and Frog 40 also have steering limiters.    

Another safety feature some first pedal bikes feature is a chainguard. This stops clothing from getting stuck and small legs from getting injured. Our bikes with chainguards that fit a 3 to 6-year-old include the Woom 2 and Woom 3 For more about these types of bikes, take a look at our first pedal guide.   

Quality & Durability  

Choosing a high-quality and durable bike for young children is key for their comfort, safety, and long-term enjoyment.   

A quality bike offers a comfortable riding experience with well-padded seats, ergonomic handlebars, and properly positioned pedals. They are also made with more durable materials and reliable components. 

A high-quality bike is less likely to suffer from significant damage, reducing the need for frequent repairs or replacements.   

At Bike Club we only offer quality bikes. Our sustainably focused model relies on bikes that can stand the test of time. This means we can refurbish the bikes and offer them to the next child when you exchange them.

Questions We Get Asked About Bikes For 3 to 6 Year Old Children  

What kind of bike is good for a 3-year-old?  

The right size bike for a 3 year old will differ for each child. A balance bike is a good choice for a 3-year-old if they are new to cycling. If they already have experience on a balance bike then they may be ready for a 14” first pedal bike.   

What size bike does a 4-year-old need?  

The right size bike for a 4 year old will depend on their height and experience. If they are completely new to cycling then a large balance bike like the Tadpole Plus is a great option. If you think your 4-year-old is ready for pedals then there are a range of first pedal bikes available. We recommend using their inside leg measurement to find the best fit.   

How do you measure a child for a bike?  

To measure their inside leg, get them to stand with their back to a wall with shoes on. Then place a book between their legs and slide it up as high as is comfortable. Mark the wall where the top of the book is, and measure from this mark to the floor. For more information, you can refer to our kids bike sizing guide.   

Is a 20 inch bike good for a 6 year old?  

A 20-inch bike could be a good fit for some 6-year-olds. The Forme Kinder 20 for example is a hybrid bike recommended for 5 to 7 year olds, with an inside leg range of 52 – 62cm. You can take a look at our hybrid bike guide for more information. There is also a 20-inch road bike for 6 year olds, the Frog 58, if your youngster is keen on road cycling.
