Kids Bikes Buying Guide
How to Choose the Right Kids Bike Whether it's your kids first bike, or they've outgrown their old set of wheels; buying a kids bike can be difficult if you don't know how to pick the right one. First things first, kids bikes are sized according to their wheel size, not their frame size like adult bikes. Size is the most important consideration when choosing bicycles for kids. The right size bike will help keep your child safe, comfortable and get the most enjoyment from their bike. Another important consideration is the frame weight. A lightweight frame that places the child in a stable, comfortable riding position will be easier to pedal and more enjoyable to ride, meaning it will get ridden much more! Bikes made with alloy frames are typically more expensive than bikes with steel frames. The benefits of alloy are that it is lighter and easier for the child to ride, as well as being less prone to rust. An alternative for older kids are BMX bikes. BMX frames are generally more heavy duty, but this does make them slightly heavier so they're better suited to more experienced riders. All kids bikes at 99 Bikes are professionally assembled by a trained bike mechanic according to a rigorous safety checklist. This ensures both a safer and less frustrating experience than assembling the bike yourself. KID'S BIKE SIZING The height of the child is more important than the child's age, however, for simplicity this guide refers to the suitability of the bike relative to approximate age groups.

Designed for kids aged 2 to 5 years old (with a height range of 80cm to 108cm), these bikes come with features that help them learn and enjoy their ride safely. Lightweight frames and smaller grips ensure little hands can steer comfortably. Many models include removable training wheels, making the transition from assisted riding to two wheels smooth and stress-free.

Low stand-over heights, stable wheelbases, and soft-touch saddles provide comfort and security for growing riders.

The main difference between the two is that a kid’s bike will be lighter and easier to ride, and a BMX will be heavier and more durable. Kid’s bikes are designed in a mountain bike style, whereas BMX are designed more for street and skate park riding. A kid’s bike may be a better option if the child is still learning to ride, while a BMX will be more suitable if the child is already confident - or if they have a tendency to be rough with things. Some 20 inch bikes also come with gears, which can be beneficial if the child is a bit more experienced and coordinated, as well as suspension for better comfort and handling. 20 inch kids bikes are best suited for kids aged between 6 to 10 years old This size is also the standard size for BMX Kids 20 inch bikes are designed as a mountain bike style, so they’re easier to ride and lighter Kids bikes are the best option if they are newer to riding BMX bikes are more durable and designed for street or skate park riding BMX are great for the more confident rider or if they tend to be rough with things!

Unlike adult bikes, which are sized by frame, kids' bikes are measured by wheel diameter. Use our handy size chart above to match your child's height to the correct wheel size. If your child falls between sizes, consider their experience and confidence level: More experienced riders can handle a larger frame, which they’ll grow into. Less confident riders will find a smaller bike easier to control and manoeuvre. Step 2: Match the Bike to Their Riding Competency Once you’ve found the right size, consider your child's riding ability and skill level: Training Wheels: If your child is just learning to ride, look for a bike that comes with training wheels, or purchase them separately. We can help with installation! Single-Speed vs. Geared Bikes: Single-speed bikes are great for beginners still learning balance and braking. Geared bikes help with tackling hills and longer rides but require more skill to use properly. Step 3: Let Them Choose Their Favourite Colour This might just be the most important step! A bike in your child's favourite colour makes for an even more exciting gift. When they love the look of their new bike, they’ll be eager to ride it. Understanding Key Features Based on Budget Once you've covered the basics, your budget will determine the frame material, braking system, and extra features that suit your child's needs. Frame Material: Alloy vs. Steel Alloy frames are lighter and slightly more expensive, making them easier for kids to ride and handle. Steel frames are more affordable but heavier, which can make riding more challenging for younger kids. Braking Systems: V-Brakes vs. Disc Brakes V-brakes (rim brakes) are more affordable and found on most entry-level kids' bikes. Disc brakes offer better stopping power and are typically found on premium models.
