Unlock a world of freedom and fun with a Kids Bike from BikesOnline AU. Our expertly selected collection is dedicated to boosting your child’s confidence with bikes that are safe, perfectly sized, and easy to handle. Every durable, feature-rich model is ready to transition seamlessly from backyard practice to extended Australian family rides.
A quality bicycle is essential for a child's safety and confidence. Our range of children's bikes meets high durability standards, ensuring a positive riding experience that encourages a lifelong love for cycling.
Every model in our range incorporates critical design elements to keep children safe and comfortable. Expect responsive braking systems with easy-to-reach hand and/or coaster brakes that allow for confident stopping. Components like brake levers and grips are sized for little hands for effortless operation. All bikes feature sturdy, lightweight frames with durable construction that can withstand learner falls, yet remain light enough for easy handling and control.
We categorize our bikes based on a child's skill development to help parents choose the ideal model.
Balance bikes are the perfect zero-hassle way for toddlers and young children to start cycling. By removing pedals, these bikes isolate the most crucial skill: balance and coordination. They feature a lightweight frame for easy handling and a low-to-ground design that allows the rider to safely place both feet on the ground for secure stopping. With no pedals or gears, the focus is solely on fundamental motor skills.
Once a child can comfortably balance, they are ready to transition to their first pedal bikes. These models prioritize low standover height and intuitive controls. Features often include optional training wheels for support during the final steps of independent riding, simple stopping mechanisms (typically a mix of coaster and hand brakes), and a protective chain guard to shield the rider from the drivetrain.
For growing riders who want to tackle paths, gravel, or light bush trails, our kids mountain bikes offer enhanced capabilities. These models bridge the gap between simple children's bikes and entry-level adult bikes, often featuring front suspension to improve comfort on uneven terrain and treaded tyres for necessary grip on dirt and grass. Some models include disc brakes for superior stopping power in varied Australian weather conditions. This is a great transition before moving to full-sized mountain bikes.
Our junior and teen bikes cater to older, more demanding riders. Available in larger wheel sizes (e.g., 26” and 27.5”), these bicycles feature multiple gears—essential for navigating varying terrain and longer distances—and sturdy frames built to withstand regular, heavy-duty use. They utilize advanced components to provide value and longevity for high-performing young riders, closely mirroring adult models like our popular range of gravel bikes or road bikes.
The correct size is the most important factor for safety, control, and comfort. Parents should prioritize matching the child’s height and inseam with the appropriate wheel size, rather than just age. Our kids’ bike size guide provides detailed metrics to ensure a perfect fit. Many bikes feature adjustable seats and handlebars to accommodate growth, ensuring the bike lasts longer. Knowing how to adjust the bike handlebars is key for proper fitment.
Completing the cycling setup involves essential safety gear, including certified helmets and protective pads. Beyond safety, customisation like baskets, bike decals, and streamers allows children to personalize their ride, fostering a greater connection to their new bicycle. We also offer a range of bike parts for maintenance and upgrades.
Mountain bikes are available in multiple different styles to take on any style of trail you choose.
