Girls 20" Wheel Bikes

A 20-inch wheel bike is generally suited to kids aged around 6 to 9 years, but height is a more reliable guide than age, so it's worth checking the recommended height range for the specific bike before buying.

If your child has outgrown their smaller bike and their knees are coming up too the handlebars when pedalling, it's time to size up. A 20-inch wheel is a natural next step from a 16-inch model and gives kids more room to grow while still offering a manageable ride.

For younger or less experienced riders, a single-speed bike is often easier to manage and requires less maintenance. If your child is more confident and will be riding on varied terrain or longer distances, a bike with a basic gear set can make riding more comfortable and enjoyable.

Most 20-inch bikes come with hand brakes, which help kids develop the stopping technique they will use on adult bikes. Some models also include a rear coaster brake as a backup, which can be useful for younger riders still building hand strength and coordination.

Yes, bike weight is worth considering for younger riders. A lighter frame is easier for kids to handle, steer, and lift, which helps build confidence especially when they are still developing their riding skills. Where possible, compare frame material when choosing between models, an alloy frame will almost always be lighter than a steel one.

A 20-inch bike works well for both school runs and casual riding in parks or on local paths. For regular commuting, look for practical features like a kickstand and reliable brakes, while kids riding mainly for fun can focus on finding a bike that feels comfortable and suits their riding style. If there are any hills along the way choosing a bike with gears will help them immensely.

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.
