Kids Bike Size Guide - Everything You Need to Know

11 February, 2020

Nothing beats getting your first real bike! Like adult bikes, it’s important to get the correct kids bike size so that your little rider is comfortable and confident.

Kids bikes are generally measured by the size of their wheels. This differs from adult bikes, which are generally measured by the size of their frame. This is because adult bikes get more specialised and need different wheels for different applications.

The key dimension for a kids bike is the diameter of the wheel. The chart below is a general guide to choosing the correct size bike for your child.

Guide to Kid’s Bike Sizes

Kids grow fast, but don’t be tempted into buying too far ahead of their correct size. A bike that’s the right size will be easier to control, making learning and confidence building much easier.

The following is a guide only. If in doubt, please visit one of our stores to test ride a bike. Different riders will be more comfortable on different bikes, so it’s always worth a test ride if possible.

Age Child’s Height (cm) Child’s Height (Feet / inches) Recommended Bike Size
2 - 5 85 - 110 cm 2' 10" - 3' 7" Balance Bike

16” kids bikes typically include training wheels to help get things started. 20” bikes can generally also be fitted with training wheels to help new riders. Reid kids bikes also have adjustable handlebars, stems and saddles to get the fit just right and give you some adjustability as the child grows.

Safety and Comfort

Small children find using rear coaster brakes the easiest way to stop, so we have added this safety feature to all of our 16” kid’s bikes in addition to the hand operated caliper brakes.

It’s also important that your little rider has a well-fitting helmet. An Australian Standards compliant helmet will provide real protection against the knocks and bumps that sometimes come with learning to ride. Check out the range of Reid Kid’s bike helmets.

Buying a quality kids bike for your child

A good quality bike gives kids a great start into the world of riding. Reid kids bikes are built light for ease of handling and tough to withstand years of being left in the rain, taken over jumps and ridden through the muddiest of puddles.

Every Reid bike meets Australian standards and is also certified by SAI Global ‘5 tick’ for safety. No other Australian bike brand even comes close to this level of certification.

Reid's Kids Bikes Lifetime Warranty

We have a range of great value kids bikes, and as per every Reid Bike you'll get 12 months of free servicing, a lifetime warranty on frames & rigid forks, plus a 2 year warranty on parts. Check out the kids bikes here.

Riding on the footpath

In all states of Australia, it’s legal for children under 12 years of age to ride on the footpath. It’s also legal for an adult to ride on the footpath if they are accompanying that child. Naturally, you are also required to ride in a manner that is respectful to other footpath users, so you should keep to the left unless overtaking, use hand signals and communicate clearly with other footpath users to reduce risk and keep everyone happy.
