Kidvelo Rookie 18 Convertible Balance Bike (5 – 8 Years)
$529.00
“The Rookie 18 in blue has exceeded my expectations. The frame is strong, the tyres grip really well, and the bike is clearly made to last. My son rides it daily and it still looks brand new. The option to switch from balance to pedals is a game changer.”
OLDER BEGINNERS. BIGGER CONFIDENCE.

Designed to Make Learning to Ride Easier

The Rookie 18 gives taller children and older beginners aged around 5–8 years room to learn at their own pace on one familiar bike. Start in balance mode to build control, then install the included Easy-Ride Pedal Kit when they are ready. At 6 kg in balance mode, it stays manageable while young riders develop confidence.

Balance First

Build the hardest riding skill before adding pedals.

Pedals Included

The Easy-Ride Pedal Kit is ready for the next milestone.

Kid-Specific Fit

Child-sized controls and stable geometry feel natural.

One Familiar Bike

No new frame or handling to relearn when pedals go on.

Aluminium Frame

Strong, corrosion-resistant construction with a durable painted finish.

Front & Rear Brakes

Short-reach levers help smaller hands learn proper braking.

Air-Filled BMX Tyres

18 × 2.0-inch tyres add grip, cushioning and stability.

Kid-Specific Geometry

Comfort Components

Kraton grips and a padded saddle suit developing riders.

Tool-Free Seat Adjustment

SIZE GUIDE

Is the Rookie 18 the Right Size?

Measure your child’s inner leg rather than relying on age alone. The Rookie 18 is designed for riders with an inseam between 48–68 cm, with a saddle height range of 48–64 cm.

Recommended Age5–8 Years
Inner Leg48–68 cm
Seat Height48–64 cm
Wheel Size18"
Balance Weight6 kg
QUICK FIT CHECK

How Should the Rookie 18 Fit?

Feet Flat

Both feet should reach the ground comfortably in balance mode.

Slight Knee Bend

A small bend helps children push, glide and stop confidently.

Natural Reach

The bars and brake levers should be easy to reach without stretching.

Room to Grow

Keep useful saddle adjustment above the starting position.

Still unsure about size?

Send us your child’s age and inner leg measurement and we can help confirm the best Kidvelo size.

LIGHTER BIKE. EASIER LEARNING.

Why Lightweight Makes a Big Difference

At 6 kg in balance mode and 7.6 kg in pedal mode, the Rookie 18 keeps both learning stages manageable. Less bike weight helps children steer, recover and stop with greater control.

Easier to Balance

Young riders have less weight to manage as they glide.

Easier to Manoeuvre

Starting, steering and recovering feel more natural.

Easier for Parents Too

The aluminium build is simpler to lift into the car or carry home.

THE KIDVELO WAY

Balance First — Add Pedals When They’re Ready

The Rookie 18 separates balance from pedalling so children can focus on one skill at a time. They first develop balance, steering, braking and control, then add the included pedal kit without changing bikes.

THEIR RIDING JOURNEY

Four Simple Steps to Confident Pedalling

01 · STAGE ONE

Walk

Learn how the bike feels with both feet securely on the ground.

02 · STAGE TWO

Glide

Take longer strides and lift the feet to discover balance.

03 · STAGE THREE

Balance, Steer ,Brake

Build reliable control before introducing the pedal kit.

04 · STAGE FOUR

Add Pedals

Keep the familiar fit and handling while learning to pedal.

Learn Balance First. Pedalling Becomes the Easy Part.

No training-wheel phase and no unfamiliar replacement bike — just a natural next step on the Rookie 18 they already know.

TWO LEARNING STAGES

One Bike. Two Ways to Ride.

Begin with the drivetrain removed for a clean balance-bike setup. When gliding, steering and braking are second nature, install the included Easy-Ride Pedal Kit and keep the same familiar bike.

A Fresh Start for an Older Beginner

After a heavy bike with stabilisers dented his confidence, their five-year-old regained interest and was balancing confidently within weeks.
