How to choose the right bike size for kids

Nothing beats getting your first real bike! Like adult bikes, it’s important to get the right bike size so that your little kids can ride comfortably and confidently.

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. It is because adult bikes get more specialised and need different wheels for different applications.

The key dimension for a kid’s bike is the diameter of the wheel rim. The chart below is a general guide to choosing the right bike size for kids.

Guide to bike size for kids

The following is a guide only. If in doubt, please visit your local stockist to test ride a bike.

Age         Height (cm)            Height (Ft/Inches)     Recommended bike size
4-7         100 – 120cm           3.4” – 4.0”                  16” wheel
7-9         120 – 135cm           4.0” – 4.5”                  20” wheel
9-11       135 – 145cm           4.5” – 4.9”                  24” wheel

Normally, 12” and 16” kid’s bikes typically include training wheels to help get things started. Likewise, 20” bikes can generally have training wheels to help new riders. Most bikes also have adjustable handlebars, stems and saddles to get the fit just right.

Special sizing for kids Fat Bikes

As kid’s bikes are sized according to the outside diameter of the wheel rim (in inches), sizing kids Fat Bikes is a little different as the tyres are very big. Moreover, this adds more height to the bike (more rubber around the wheel rim). Hence, consider this when referring to sizing charts. For example, a regular 20” kids bike would be suitable for a child aged 7-9 (120-135 cm). However, the 20” kids Fat Bike is suitable for a child aged 7-10 (125-140 cm).

For ease of use, consult the chart below for our range of kids Fat Bikes:

Age           Height (cm)          Height (Ft/Inches)      Recommended bike size
4-7            100 – 125cm         3.4” – 4.1”                   16” wheel
7-10          125 – 140cm         4.1” – 4.6”                   20” wheel
10–13       140 – 150cm         4.6” – 5.0”                   24” wheel

Safety and comfort

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

Also, it’s important that your little rider has a well-fitting helmet. It will provide real protection against the knocks and bumps that sometimes come with learning to ride.
