Most children start on a balance bike between 18 months and 3 years, once they walk confidently and can put both feet flat on the ground when sitting. Size matters more than age: it is the seat height, set to the inside-leg measurement, that decides. This guide explains how to spot the right moment, then how to choose a light, adjustable and safe model.
A balance bike is a small bike without pedals. Your child moves forward by walking while seated, then by pushing off the ground with both feet, and eventually lifts their feet to glide. It teaches balance before pedalling, the reverse order of a bike with stabilisers.
Balance bike: what age to start?
There is no official age for starting on a balance bike. No health authority sets a threshold, and manufacturers give wide ranges, often from 18 months to 5 years. The right benchmark is motor development: your child should have been walking for several months, be able to run a little and climb onto a small seat unaided.
Before 18 months, most children do not yet have the stability or leg length they need. They manage better on a four-wheeled ride-on, covered in our guide to the baby ride-on. Between 2 and 3, the balance bike often takes over. After 3, it stays useful for another two or three seasons.
Signs your child is ready
- They walk without holding on and run a few metres without falling.
- Sitting on the seat at its lowest setting, they put both feet flat on the ground, knees slightly bent.
- They can lift the bike and move it a metre or two on their own.
- They show interest: they push an older sibling’s ride-on or ask to get on.
The legs do a lot of work on a balance bike. Jumping and climbing games are good preparation, as our articles show on the age when babies jump with both feet and on the baby who climbs everything.
Toy or bicycle: what the regulations say
In Europe, a balance bike can fall under two different regimes depending on its seat height. Directive 2009/48/EC on the safety of toys excludes from its scope bicycles with a maximum seat height of more than 435 mm. Below that, the bike is treated as a toy and must carry the CE marking.
Above 435 mm, you enter the category of bicycles for young children. The ISO 8098:2023 standard covers models with a maximum seat height between 435 and 635 mm. It sets strength and braking requirements closer to those of a real bike.
For a toddler, most balance bikes stay below 435 mm and therefore count as toys. The new European regulation is gradually replacing the directive, as explained in our article on the European toy safety regulation. Either way, buy a product that clearly states its compliance.
How to choose a balance bike
Five criteria really count. The rest is a matter of taste. Here is the order in which to look at them.
Seat height, set to the inside leg
Measure your child’s inside leg, barefoot, from the floor to the crotch. At its lowest, the seat should sit about 2 to 3 cm below this measurement. That way your child puts their feet flat with knees slightly bent. A seat that is too high leaves them on tiptoe and makes them topple sideways.
Check the maximum height too. An adjustment range of around ten centimetres lets the bike keep up with growth for two or three years. A fixed seat soon turns out to be too low, within a few months.
The weight of the bike
A balance bike that is too heavy tires your child out and puts them off. A handy rule of thumb circulates among specialist retailers: no more than about 30% of the child’s weight. It is not an official rule, but it helps when comparing. For a 12 kg child, a model weighing 3 to 4 kg is comfortable.
Wheels and tyres
Wheels of 10 to 12 inches suit the youngest riders. EVA foam tyres never puncture and are light, which works well on pavements and paths. Air-filled tyres absorb bumps better on grass and tracks, but need maintenance. Avoid hard plastic wheels, which slip and pass on every jolt.
The brake
Before the age of 3, children brake with their feet, and that is perfectly normal. A hand brake only helps if it is made for a small hand, with a short lever and a gentle pull. On a toddler model, a badly sized brake is useless.
Steering and finish
Some models limit how far the handlebars turn, which prevents falls from sudden sharp turns. The grips should have wide end caps that protect the hands against a wall. Check for sharp edges, protruding screws and small parts that come loose.
Wood, metal or aluminium: which material?
Wood is pleasant and durable, but often heavier and less adjustable. Metal is sturdy and inexpensive, at the cost of extra weight. Aluminium is the lightest for the same size, which matters for a 2-year-old. The choice depends above all on the final weight and the adjustment range, not on the material alone.
Think about how it will really be used. A balance bike that is mostly ridden in a garden or park does not have the same needs as one carried every day to nursery. In the second case, a light model with a carry handle makes a parent’s life much easier.
Does a child need a helmet on a balance bike?
Yes, from the very first tries. In France, helmets have been compulsory since 22 March 2017 for children under 12 on a bike, whether riding or as passengers, under décret n° 2016-1800 (a French government decree). An adult accompanying a child without a helmet faces a fine of 90 euros.
The rule covers cycles. It is not clear whether a toy balance bike used in a garden falls under this obligation. The need for caution is the same: a child falls at the same speed and from the same height. Choose a helmet in the right size, well fitted and fastened, and make it a habit from the start.
Learning to ride a balance bike: the stages
- Walking while seated: your child moves forward step by step, the seat beneath them, hands on the handlebars.
- Running while seated: the steps get longer and your child picks up speed.
- Gliding: they lift both feet for a few metres, then for longer and longer.
- Turning and braking: they learn to steer and to stop with their feet.
Choose flat, open ground, away from traffic and slopes. Let your child explore at their own pace, without holding the seat, which throws off their balance. Allow a few weeks to a few months between the first seated steps and the first glides.
This milestone does not replace the need for floor play at home. On rainy days, a Treelys play mat offers a cushioned space for crawling, jumping and rolling, the very movements that build the same balance. To place the balance bike within overall motor development, see our guide to the early awareness of danger.
Balance bike or bike with stabilisers?
A bike with stabilisers teaches pedalling, but not balance. Your child leans on the stabilisers and has to relearn everything the day they come off. A balance bike teaches balance first. Many children then move straight on to a pedal bike, without stabilisers.
It is not a must. Some children prefer to pedal straight away and do very well. If your child refuses the balance bike for several weeks, put it away and offer it again later.
Buying second-hand, reselling, passing it on
A balance bike is easy to pass on. Before buying second-hand, check the play in the handlebars, the condition of the bearings and how tightly the seat clamps. Foam tyres are rarely replaceable; if they are split, walk away. A good balance bike often serves two or three children in turn, which makes it a sensible purchase.
Key takeaways
- Children start on a balance bike when they walk confidently and put their feet flat when seated, often between 18 months and 3 years.
- Seat height is set to the inside leg, about 2 to 3 cm below it.
- A light bike, a wide adjustment range and suitable wheels matter more than the material.
- A helmet is compulsory on a bike under 12 and essential on a balance bike.
