20" Wheel Geared Kids Bikes (Ages 7-9)

These bikes are designed for children aged 7 to 9 years old, however height is a better guide than age. The best way to confirm fit is to check that your child has a slight bend in the knee at the bottom of the pedal stroke.

If your child has mastered balancing, steering, and braking on a single-speed bike, they are likely ready to learn how to use gears. Gears help kids manage different terrain and longer distances more comfortably, making rides more enjoyable as they grow in confidence.

Most 20-inch geared kids bikes come with a modest gear range suited to beginners, often featuring a single front chainring and a small rear cassette with anywhere from 3 to 8 gear options. This keeps shifting simple enough for young riders to learn without being overwhelmed by too many options.

Yes, frame weight makes a noticeable difference for younger riders. A lighter bike is easier for a child to handle, manoeuvre, and lift, which builds confidence and reduces fatigue on longer rides. Where possible, look for aluminium frame options over heavier steel alternatives.

These bikes are well suited to neighbourhood riding, park visits, and family weekend rides on sealed paths and light off-road tracks. They are not designed for aggressive trail riding but handle everyday riding conditions comfortably for kids in this age group.

If your child has outgrown their current bike or is finding single-speed riding limiting on hills or longer routes, a 20-inch geared bike is a natural next step. Check that your child can reach the handlebars comfortably without overstretching, as a proper fit supports better control and riding posture.

Finding the right bike size can feel tricky, as different bike types have slightly different geometries. To make it easier, we’ve created a Find Your Size tool. Simply enter your height and inseam measurements (or those of the person you’re shopping for), and we’ll recommend the best size for each bike and pre-select the recommended option for you.

Not sure of your inseam measurement? No worries! We provide an estimated inseam measurement based on your height to help keep your recommendation as accurate as possible.

You can find the tool on each product page or at the top of categories when browsing. Try Find Your Size.
