Kids' bikes are measured by wheel size instead of frame size
Unlike adult bikes, which are measured by frame size, kids' bikes are measured by wheel diameter. These sizes range from 30.4 cm to 66 cm (12” to 26”), accommodating the smallest children to the tallest.
Age and height help determine a size bracket
Your child's age and height are key factors in determining the appropriate wheel size. Start by measuring your child, then refer to the sizing guidelines below to find the best wheel size options for them.
Knowing their inside leg measurement helps find the best fit
After determining the appropriate wheel size, consider measuring your child’s inside leg as well. This measurement is crucial for ensuring the bike is comfortable for them to stand over and easily get on and off.
Kids’ bike size chart
Size brackets for kids' bikes are broad and often overlap. Additionally, bikes can fit differently even if they share the same wheel size. Visit your local bike shop with your child for some enjoyable test rides! Pro tip: if your child is over 12 years old and/or taller than 1.5 m (4’ 8”), you can begin considering adult bikes.

Keep an eye out for these cues not only during test rides at the shop but also as your child grows and develops their skills.
Seat height
Ensuring your child’s seat is at the correct height is crucial. Adjust the seat as they gain skills and confidence. For balance bikes and their first bike without stabilisers, your child’s feet should be flat on the ground when seated. For bikes with stabilisers and for more confident riders on pedal bikes, only their toes should touch the ground.
Knee position
Knee position is closely tied to seat height. When kids are just starting out, their knees should be more bent so they can easily place their feet on the ground, boosting their confidence. As they become more comfortable, you can raise the seat to allow full leg extension for better pedalling efficiency.
Standover height
Ensure your child can comfortably stand over the bike with their feet flat on the ground, leaving an inch or two between them and the top tube. This helps them feel secure when stopping and getting on and off the bike.
Foot position
For balance bikes, kids need to have their feet touching the ground to propel the bike. On bikes with stabilisers or pedal bikes, your child will be most comfortable with the balls of their feet resting flat on the pedals.
What’s the best kids’ bike to get my child?
Selecting the right bike for your child can be challenging given the many options available! The key is to match the bike’s purpose and features with your child's skill level. For instance, most young children will ride short distances around the neighborhood and benefit from a simple, hybrid-style bike without extra features. As they grow older and develop more skills, they'll have a wider range of bikes with various features to choose from. Pro tip: Girls' and boys' bikes are essentially the same, differing mainly in colors and graphics.

Kids’ hybrid bikes
These bikes are outstanding for all-around riding. They are designed for comfort and confidence on every ride, whether on roads, light gravel paths or even detours across the lawn. They're typically equipped with tyres designed for traction on a variety of surfaces.
Kids’ mountain bikes
Some kids' bikes might look tough but are meant for roads. Genuine youth mountain bikes are crafted for off-road adventures with features like knobby tires and suspension forks. If your child is skilled in handling, shifting gears, and braking, and is excited about trail riding, it might be time to get them a mountain bike.
