It started with a call, a month earlier: a grandmother was looking for an AEROZO bike for her grandson, but we didn't have one available right away. In July, the family — visiting from Belgium on holiday — was passing through Cannes. We met at their hotel so the boy could finally try it.
The moment he got on, he didn't want to stop. The grandfather and father have been club cyclists their whole lives; the boy watches the Tour de France with his dad and dreamed of a bike « like his ». That day, between two laps of a hotel car park, we watched a real passion take shape.
This meeting sums up exactly why this project exists: passing on to the next generation the passion and family values around cycling that already unite three generations in this family.
« It's a really beautiful bike. »— The grandfather
« It's so beautiful, it's so beautiful! »— The boy
« I searched everywhere to see if the brand really existed. The day we saw it in person, I understood why there wasn't much online — they've only just started. »— The mum
Behind the scenes at AEROZO
This is what we’re building. Want to be part of it?
The
First one.
The very first prototype ever assembled in AEROZO's history.
Where the idea became reality.
Light. Strong. Precise.
The standard starts with the frame.
Every gram counts. Never at the expense of strength or finish.
The material,
where it matters.
Double-butted aluminium tubes: reinforced at stress points,
thinned at the centre to cut weight without compromising strength.
The right posture
starts with the
right dimensions.
A geometry built to the child's scale.
Every dimension is engineered for a natural, stable position suited to riding a true road bike.
Every joint
matters.
Hand-filled and finished joints for continuous lines and a seamless surface before painting.
Precision
to the millimetre
Stiffness. Alignment. Reliability.
A rear dropout precisely assembled to guarantee stiffness and alignment.
The same standard.
Down to the fork.
Hand-filled joints for a seamless, perfectly smooth finish before painting.
Weight
isn't a detail.
A fork weighing just 534 g.
Because on a junior bike, shaving weight off every part means every pedal stroke feels easier.
Strength
starts here
Welded. Checked. Reliable.
Every weld is made with precision, then checked to guarantee strength you can rely on.

Frequently asked questions
Understanding road cycling junior
Size, biomechanics, safety, drivetrain and learning: the essential answers to choose a true 20-inch children’s road bike designed to learn properly and progress with confidence.
Child biomechanics
114 mm cranks, coherent position and more natural pedaling.
Safety & control
Dual brake controls to keep control from the top of the handlebar.
Mechanical simplicity
Intuitive 1x drivetrain, without unnecessary chain crossing.
At what age can children start road cycling?
Children can discover road cycling from around 6 to 9 years old, provided they are comfortable on two wheels and use a bike truly adapted to their size, inseam and strength.
The goal is not to push children into competition too early, but to give them a coherent bike to learn the right fundamentals: position, lines, braking, cadence and accelerations.
Why choose a true children’s road bike instead of a standard bike?
A true children’s road bike is not a miniature adult bike or a simple children’s bike with drop bars. It must be designed around the morphology of the young cyclist: geometry, cockpit, braking, drivetrain, weight and components.
The goal is to offer a healthy, precise and reassuring riding feel. A bike that is too heavy, too long or poorly proportioned makes learning harder, creates unnecessary fatigue and can damage confidence.
What size for a 20-inch road bike?
A 20-inch road bike generally suits children aged around 6 to 9, depending on their size, inseam and confidence on the bike. Age alone is not enough: two children of the same age can have very different needs.
The right size allows children to remain stable, brake correctly, pedal naturally and keep control of the bike without excessive compensation.
Why do 114 mm cranks better respect children’s biomechanics?
Crank length directly influences pedaling motion. On many children’s bikes, cranks are too long compared with leg length: children lift their knees excessively, lose fluidity and experience more stress around the hips and knees.
114 mm cranks allow a more natural rotation, better cadence and smoother pedaling. They help children produce a more fluid effort without forcing a range of motion designed for larger bodies.
What is the purpose of dual braking with additional controls on the handlebar?
Dual brake controls allow children to brake from the hoods, but also from the top of the handlebar. This is a real advantage for learning because young cyclists often ride with their hands on top, in a more natural and reassuring position.
Keeping immediate access to braking improves control, reduces stress and allows children to progress more calmly. They gradually discover the different positions of a road handlebar without losing braking safety.
Why choose a 1x drivetrain on a junior road bike?
A 1x drivetrain greatly simplifies bike use. Children do not have to manage a front derailleur, small and large chainrings, or chain crossing. One control is enough to understand gears and adapt effort.
This simplicity reduces mental load and lets children focus on what matters: line, braking, cadence, balance and enjoyment. It is also lighter, more reliable and easier to maintain.
Why is weight so important on a children’s bike?
For children, bike weight represents a much larger share than for adults. A few hundred grams can already change handling, accelerations, climbs and riding enjoyment.
A lighter bike is easier to control, creates less fatigue and makes children want to ride longer. For young cyclists, lightness is not a luxury: it is a real factor in progression and confidence.
Why is geometry essential on a junior bike?
Geometry defines the child’s position on the bike, stability, responsiveness and ease of handling. Poorly adapted geometry can place children too far from the handlebar, too high, too low or in an unnatural posture.
True junior road geometry must allow a dynamic but controllable position, with an accessible cockpit and healthy handling. This is the foundation for learning properly.
Children’s road bike or children’s race bike: what is the difference?
In everyday language, many parents say children’s race bike to describe an efficient, lightweight bike made for road riding. The term children’s road bike is more precise in cycling language.
AEROZO brings both intentions together: the desire for a true 20-inch race bike, with the technical coherence of a junior road bike designed for children.
Is a children’s road bike only for racing?
No. A junior road bike can be used for discovery, family rides, club training or first sporting experiences. Performance is not the only goal: enjoyment, confidence and learning are essential.
A good bike simply gives children better sensations and the desire to ride more often.
