Congratulations on deciding to get the child in your life riding. Choosing the right bike can be daunting. How do you strike the right balance between safety and fun? Read our tips to buying a child’s first bike, or download an information sheet.

1. Bike Style

Choosing the style of a child’s first bike depends on their confidence, age and coordination.

A balance bike

Designed for children 18 months to 3 years, they have no pedals and are move when the child to pushes with their feet. These bikes teach balance, movement and steering without having to coordinate pedals and brakes.  

A bike with training wheels

Designed for children 2 and up who have developed better balance and motor skills.  Children will need to pedal to make the bike move, but training wheels provide support to keep the bike upright and can be removed when you child can balance by themselves.  

A standard two wheel push bike

For children who have developed the confidence and skill to ride a bike without training wheels. This level varies from child to child but is usually around five.

2. Size

Once you have chosen the right style of bike, it’s time to choose the right size. Below is the recommended wheel size, based on age and height

Wheel Size

Age Height
12” 2-3 85-100 cm
14” 3-4 95-110 cm
16” 4-5 110-120 cm
20” 5-8 120-135 cm
24” 8-11 135-145 cm



145+ cm

We recommend you take the child for a test ride first, and most bike stores are happy to help.

The bike should not be too big or too small. They should be able to:

  • straddle the middle of the upright bike with their feet flat on the ground, with a clearance of around five centimetres.
  • not hit their knees or legs on the handlebars when riding. Their legs should have a slight bend when the pedal is at its closest point to the ground.
  • to completely turn the handlebars left and right without being overstretched

As the child grows, the adjustability of the bike seat and handlebars will ensure the bike can be used for longer.

3. Gears

One gear is the standard for children’s bikes. As they develop and the bike increases in complexity more gears will be added to the bike.

4. Tyres

Depending on where your child will be riding, the tyres will be different.

For new riders we recommend tyres with more tread, as they can handle rough terrain better i.e grass.  Tyres with little tread are better for sealed environments i.e. roads, footpaths etc.

5. Brakes

There are 2 main types of brakes that are common on children’s bikes.

  • Coaster - used when the child does not have the strength to activate the hand lever (usually up until 5 years). Used by pedalling backwards
  • Hand Lever - once a child has the hand strength, bikes are more commonly fitted with a hand lever. Used by squeezing on the lever.

6. Safety Equipment

It is Australian law that all bike riders must wear a helmet.

The main thing here is the 2 (adult) fingers rule. The helmet should sit 2 fingers above the eyebrows and you should be able to run 2 fingers under the chin strap. Also the triangles of your strap should sit underneath the ears.

You must also ensure that the bike is fitted with a working warning device i.e. a bell

7. Price

The overall cost of the bike depends on its features and the material it’s made from. Steel bikes are highly durable and can withstand most adventures children have, but they can be heavy.  Aluminium bikes, weigh less, are durable but more expensive.

Bicycle NSW recommends heading down to your local bike shop for advice on the right bike.
