Balance Bike Guide


Balance Bike Guide

Balance bikes are the simplest type of bike and are the best way to for children to learn how to ride. With no pedals or stabilizers, balance bikes give children the chance to develop balancing skills in their own time.

Children sit on the saddle of a balance bike and steer while they walk or run the bike along. Stopping is a simple matter of putting their feet down. Once they get the hang of it, kids can just pull their legs up and cruise along. Finding balance is the foundation to cycling and is best learned early.

What to look for in a balance bike


Most balance bike frames and forks are made from aluminium alloy which is lightweight and strong. Steel frames and forks are a lot heavier. The weight of a balance bike matters just as much as an adult bike as a heavier bike will be more difficult to ride.

Some early balance bikes had wooden or plastic frames, but these are less common now. While heavier than alloy these frames are more adjustable, making it easier for the bike can grow with the rider.

Wheels & Tyres

Most balance bikes come with 12” wheels, which are ideal for kids about 2-4 years old. Some come with even smaller 10” wheels, allowing for children as young as 1 year old to begin their cycling journey. Larger 14” wheels give kids as old as 6 years a chance to find their balance before moving up to a bike with pedals and a drivetrain.

Tyres provide bump absorption on a balance bike and come either as normal inflated tyres with tubes or with foam inserts. Inflated tyres offer greater cushioning, while foam inserts allow greater peace of mind from ride-stopping punctures.

Some balance bikes come with footrests to place little feet on when not running the bike along. This gives children the opportunity to rest their feet once they get the hang of balancing. A step up towards pedals footrests allow the child to coast along on two wheels in a similar way to a pedal bike.

Balance bikes are generally focused entirely on getting those essential balance skills developed. Many don’t come with brakes, as it’s easy enough to control the speed by putting feet down, however some balance bikes add in the extra safety factor and learning curve of a brake. These are useful when a child is more confident coasting along with their feet on the footrests.



Balance bikes need to grow with the child so that their feet touch the floor when they’re sitting on the saddle. Most balance bikes have an easily adjusted seatpost that allows for this growth. Some balance bikes are supplied with an additional, longer seatpost that allows for more growth.

Some balance bikes have adjustable frames that can be adjusted to offer the best fit as your child grows.

Because children must stay seated saddles on balance bikes can make the difference between a happy cycling experience and an uncomfortable one. The shape of the saddle can also play a large part, as it’s often the place where kids rest their whole weight, so a concave shape will help hold them in place. Some saddles come with little handles on the back. These help both kids and parents to carry the bike around, and also assist in keeping balance when teaching kids.
