Like getting your first car, the first bike is an important milestone for any child. It’s not only great for their ability, but also their confidence.

I remember how proud my eldest child was when she finally began to ride her bike without the assistance of training wheels. I bought it from her wish list her birthday – and along with my husband’s chef knife, I made two wins that year!

With where we live in inner city Melbourne it also feels like a necessity! Bikes are everywhere – along with great bike tracks – and many kids ride them to school.

It all began by choosing the right bike. This was more difficult than we had anticipated – our daughter was outside of all the ‘normal’ percentiles and there wasn’t a piece of advice that said here’s the best bike for your child.

We did eventually find a bike suitable for her and learned a lot along the way that has helped shape our choices for our two youngest children. There are actually many things to consider when looking for a top-rated kids bike – and age suggestions aren’t always enough.

In this guide, we’ll walk you through what to look for in good bikes for kids to help you find the perfect bike for your child – whether you’re looking for the best first bike Australia has to offer or the best youth mountain bikes.

How To Find The Best Kids Bike Australia 2021

Bikes come in a variety of shapes and sizes and so do children, so it’s important to ensure that you buy the right size bike for your child. Whilst some people buy a bike that their child will “grow into” this can be dangerous as it means the bike will initially be the wrong size. Here are some of the different sizing elements to be aware of when searching for the best bikes for kids Australia has to offer. 

Dimensions of the bike

Perhaps the most important factor to consider when purchasing the best kids bike for your child is the bike’s size.  Whilst the overall size of the bike is important, you should also consider other dimensions such as the size of the tyres, seat height as well as handlebar and pedal positioning to get the perfect fit for your child.

If these factors are not taken into consideration the bike could potentially be a danger to the child.

Tyre Dimensions

The most common way of determining a kids bike is by the diameter of the tyre.  Generally, kids bike wheel sizes come in the following tyre sizes:

  • 12”: 18 months to 4 years old;
  • 14”: 3 to 5 years old:
  • 16”: 4 to 6 years old;
  • 20”: 5-8 years old; and
  • 24”: 7 to 10 years old.

The above guide should not be used in isolation though as it is important to also consider the bike dimensions discussed below.

Scroll down to see lightweight kids bikes.

Seat Height

One of the best ways to determine if the size of a bike is right for your child is the seat height.  Given many brands don’t advertise their bikes seat height, this information can be tricky to come by and so often the best way is by having your child try it out in person.

Provided your child has mastered the bike’s brakes, the seat height should be around 2.5 to 3.75cm (1” to 1.5”) taller than the child’s inseam (the measurement of the inside of the child’s leg to their crotch).

For children that have not mastered the brakes or are not confident riders, then it is best that the seat height matches their inseam (the child is able to place their feet fully flat on the ground).

Standover Height

The standover height refers to the height required to stand over the top tube of the bike (the tube which connects the front of the bike to the back).  Your child should be able to comfortably stand over this with 3 to 5 cm (1.2″ to 2″) clearance.  This clearance protects the child from hurting themselves should they slip off the seat.

Too often you see little kids on these giant kid bikes, which is quite a serious hazard.


It’s important to ensure there is enough room between the handlebars and the seat to ensure the child’s knees don’t hit the handlebars when turning (this space is referred to as the cockpit).  The shape of the handlebars can also impact this space.  For example, large handlebars that sweep back as opposed to ones that stick straight out will impact this space.

It is also critical to check the height of the handlebars.  Too low or too high and this will put pressure on the child’s neck, shoulders and back.  The best handlebar height for a child is usually low to mid rise, so their hands are in line with their hip area.

Which is the best balance bike to buy?


The last dimension to consider is the positioning of the pedals, also referred to as the Q-factor.  The Q-factor is the distance between the inside edges of the two pedals.  If the pedals are too far apart the child will need to splay their legs out to pedal.  If the pedals are too close together the chance of the child hitting their ankles increases.

The Q-factor is particularly important for small or petite children.  These children would benefit from a bike with a narrow Q-factor.

Weight of the bike

The weight of the bike is very important.  No doubt at some stage your child is going to fall off their bike and given the bike may well fall on top of them, it’s important you look for a lightweight bike. It’s also important that a lightweight kids bike is light enough for the child to easily maneuver it around.

Ideally, the best first bike for your child should be no more than 40% of their weight. Often this is not always possible, particularly if your child is light as a feather – so just go for the bike that is close as possible to this weight guide.

The weight of the bike is going to depend largely on the size, the material it is made out of and the type of tyres.  You should be able to determine a bike’s weight fairly easily as all the best bike brands for kids display their bikes’ weight.


Australian standards require that a child’s bike must have at least two braking systems with one of those systems to be a back pedal brake (sometimes referred to as coaster brakes).  Usually, the other method will be handlebar brakes.

Whilst back pedal brakes are required by law, they can be problematic for younger children.  When young children learn to ride they often pedal both forwards and backwards.  Of course, back pedal brakes prevent this method of pedalling and often unexpected sudden stops cause children to lose their balance and at times fall off their bike.

Recently experts tend to prefer the handlebar brakes as the better option for children bikes.  Handlebar brakes don’t impact child’s pedalling.  However, there are still a few things you need to look out for.  It’s important to ensure the hand brakes are easy to activate by little hands.  A good test for this is to see if you can activate the brakes with just your pinky finger.

It is also worth noting whether the handlebar brakes stop just the front tyre or both tyres.  For handlebar brakes that only stop the front tyre when the brake is applied the rear tyre will lift off the ground causing the child to go flying across the handlebars.  Try and find a bike that the handlebar brakes stop both tyres.

Types Of Best Bikes For Kids

Balance Bikes

You have probably heard of a balance bike and wondering what they’re all about and if they are actually worth the hype.  Basically, a balance bike is a two-wheeled pedal-less bike designed to teach young children (as young as 18 months) how to balance on two wheels.

The beauty of balance bikes is that the child is putting all their efforts into balancing rather than pedalling, this provides them with the skill of balance so they can go straight to a regular child’s bike without the need for training wheels.

Unfortunately, bikes with training wheels teach children to pedal, but not to balance.  Therefore once the training wheels are removed from the bike the child needs to learn how to ride their bike all over again.

The best balance bike is recommended for children from the ages of 18 months to 5 years of age.  Generally, children progress to a typical child’s bike after 2 years of riding the balance bike. The best toddler bikes or best bike for 2 year old Australia tend to be balance bikes for all of these reasons.

Road Bikes

Road bikes are good all rounder bikes, designed for riding on the road, and are often some of the best childrens bikes.  These best kids bike brands have narrow tyres designed for riding on smooth surfaces and to go as fast and as far as possible out on the open road.

Mountain Bikes

Mountain bikes are designed to handle all kinds of terrain, particularly unpaved surfaces. The best youth mountain bike will have thicker more durable tyres in order to be able to go over small rocks, branches and logs and gears. Mountain bikes do tend to be a little on the heavier side but there are also lighter models if you’re looking for the lightest kids mountain bike. 

Below are some of my favourite options for good mountain bikes for kids.

BMX Bikes

BMX bikes for kids are ideal for older children who are confident riders and are into bike racing and / or tricks.  There are various types of BMX bikes depending upon the different purposes such as off-road racing, street racing and stunts.  Kids have always loved BMX bikes mainly due to their smaller sizes and quite frankly just because they are cool!

Of course, you are always going to be limited by what you are able to spend when buying a bike.  However now that you know exactly what to look for in a bike, you will be able to prioritise what is important and purchase the best bike for your child within your budget.

Whilst the cheapest bike you find is generally not going to be the best bike for your child, similarly, the most expensive bike is unlikely to be the best bike either.

If budget is of a concern to you, you can always purchase a second-hand bike, or better still by the best bike you can for your child brand new with the mindset to resell it once your child outgrows it.

If you do plan to resell it, be sure to keep receipts, spare parts, reflectors, instructions etc to maximize the resale value.  Another tip is to buy the bike in a neutral colour so it can suit a boy or a girl.
