It’s Never Too Late To Learn To Ride. Perfect bike for 5, 6, 7, 8 year old with a Leg Inseam 48cm to 68cm

Key Features

The Rookie 18 is designed for older and taller children who are learning to ride, giving them the confidence-building benefits of a balance bike before converting into their first pedal bike.

Quick Fit Guide

  • Best Age Range: 5–8 years
  • Best Leg Inseam: 48–68cm
  • Wheel Size: 18″
  • Balance Bike Weight: 6kg
  • Pedal Bike Weight: 7.6kg
  • Maximum Rider Weight: 100kg

Balance Bike That Converts to a Pedal Bike

The Rookie 18 starts as a full-size balance bike so your child can master balance, steering and braking first. When they’re ready, install the included Easy-Ride Pedal Kit and convert the same familiar bike into their first pedal bike.

Perfect for Older Beginner Riders

The larger 18″ format gives older or taller children the opportunity to learn balance-first riding without having to start on a bike that’s too small for them.

Learn Balance First — Then Add Pedals

By developing balance and control before introducing pedals, children can focus on one skill at a time. Once they’re confidently gliding, the pedal kit can be added without changing to an unfamiliar bike.

Lightweight Aluminium Frame

At just 6kg in balance bike mode, the Rookie 18 remains lightweight and manageable for its larger wheel size, helping children steer, manoeuvre and control the bike with greater confidence.

Low Step-Through, Kid-Specific Geometry

The low frame design makes mounting and dismounting easier, while Kidvelo’s child-specific geometry places the rider in a stable and comfortable position for better balance and control.

Integrated Footrest for Balance Riding

Once your child builds speed, the integrated footrest gives them a natural place to lift their feet while gliding — helping develop the balance skills needed before moving to pedals.

Child-Friendly Braking

Proper brakes and child-sized controls help riders learn how to slow down and stop confidently, developing important bike-handling skills from the beginning.

18″ Air-Filled Tyres

Large pneumatic tyres provide excellent grip, cushioning and stability, while the bigger 18″ wheels roll smoothly across footpaths, parks, grass and uneven surfaces.

Adjustable Fit That Grows With Them

The adjustable saddle and handlebars allow the Rookie 18 to be fine-tuned as your child grows, extending its useful life through both balance and pedal-bike stages.

Why Parents LOVE IT

🔄 Two Bikes In One
Starts as an 18″ balance bike and converts into a proper pedal bike with the included Easy-Ride Pedal Kit when your child is ready.

🎯 Gives Older Beginners a Better Way to Learn
The larger 18″ size lets older and taller children learn balance first instead of being pushed straight onto pedals and training wheels.

🚲 Builds Real Riding Skills First
Children develop balance, steering, braking and control before pedals are introduced, helping make independent riding feel more natural.

💰 One Bike for Both Learning Stages
Instead of purchasing an older-child balance bike and then replacing it with a separate pedal bike, the Rookie 18 gives families both stages in one premium bike.

The Rookie 18 stacks up very well against the competition, with good looks, smart design, safety features that Mum and Dad will appreciate, and a price that’s solidly in line with other 18” balance bikes on the market today. If you’re shopping for your child’s first balance bike, give the Kidvelo Rookie 18 serious consideration.

Frequently Asked Questions About Rookie 18 Balance Bike

The Rookie 18 is a larger 2-in-1 convertible bike designed for older kids. It starts as a balance bike to build confidence, then easily converts into a pedal bike with the included Easy-Ride Pedal Kit — meaning you only need one bike from start to finish.

The Rookie 18 is ideal for kids aged 5 to 8 years old (105–135cm tall). The adjustable seat height (48–65cm) and adjustable handlebars mean it grows with your child and offers a longer riding lifespan.

Conversion takes just a few minutes with simple tools. The process is quick, parent-friendly, and doesn’t require any mechanical skills — just attach the pedals, chain, and you’re ready to ride.

Many kids skip the bike stage when younger, or struggle with training wheels. A larger balance bike like the Rookie 18 lets them master balance first, build confidence, and then transition to pedalling quickly — often within the same day.

No. The lightweight aluminium frame (under 8kg even with pedals) makes it easy to manoeuvre, lift, and ride. It’s far lighter than most steel-frame bikes in this size range.

Yes, it features front and rear hand brakes, giving kids reliable stopping power whether they’re gliding or pedalling. This builds good braking habits early.

 

Built with a strong alloy frame, quality bearings, and air-filled tyres, it’s designed to handle everyday use, rougher play, and is backed by a 5-year frame and fork warranty.
