Sizing Guide

When choosing a bike for your child, it’s essential it’s the right size and suits their stage of development.

As your child grows, learns and progresses, LittleBigs unique frame will grow with them (with a saddle ranging from 32cm to 52cm), ensuring they always ride a perfectly fitting bike.

With the LittleBig, you don’t need to choose between a balance bike or a pedal bike; it’s three bikes in one!

Mode 1 – Little Balance Bike
Mode 2 – Big Balance Bike
Mode 3 – Pedal Bike

Top Tip!

Getting the right size bike for your child is very important. If the bike is too little, or too big, it will not be as safe, comfortable or enjoyable to ride. The LittleBig's unique growing frame means it will fit your child perfectly for many years.

How To Check If LittleBig Will Fit Your Child

The LittleBig convertible balance bike will work for children age 2 to 6 years old.

To start on the balance bike comfortably, your child should be able to have their feet flat on the ground while sitting on the saddle.

They will need to have a minimum inside leg length (with their shoes on) of 32cm to start using the bike in little balance bike mode. The maximum inside leg to fit the bike comfortably is 52cm.

How to measure inside leg length

With your child wearing their shoes, stand them with their back against a wall.

Place a book against the wall between their legs.

Move the book up as high as is comfortable.

Measure from the top of the book to the floor and this is the inside leg length.

How Do You Know When your Child Is Ready For Pedalling?

In order to start pedalling on the LittleBig bike, your child’s inside leg length needs to be approximately 42cm. As well as fitting the bike correctly, your child should also be able to:

Coast along with their feet up
Able to make controlled turns
Preferably able to use the balance bike’s brakes (if it has them)
Have the strength to pedal the bike
