Bicycle size chart for kids

The size of a frame of a bicycle (a skeleton) is height and length of a frame, the size (15, 16, 17, 18, 19, 20, 21 etc.) in inches, centimetres (44, 45, 46, 47 etc.) or conditional units (XS, S, M, L, XL) in bicycle size chart. More often the vertical (seat tube) is measured, sometimes the length of the upper tube (from the steering wheel to the saddle). Check out our bicycle size chart for kids and find the right frame for your size bicycle!

When choosing a bike, start with the size of the wheel and the size of the frame. Different types of frame provide different (vertical, inclined, lying) landing and several sizes of a frame of a bicycle under different growth.

Bicycle frame

The classic diamond-shaped bicycle frame is divided into two triangles by a seat tube. A comfortable, correct fit requires the right bike frame to be selected and the saddle length, handlebar stem and handlebar inclination to be adjusted. The main types of frames are shown in the table.

The bike frame in the model range is made in several sizes: mountain bikes in 3 – 5 sizes, road 2 or 3 variants, and folding in one universal shoe.

The frame of a child’s bicycle has a size for a certain diameter of the wheel: the size of the wheel makes it easier to determine how to choose a child’s bicycle (table of child’s bicycle sizes)

The bike frame size table is needed to select the height of the bike frame. The shootout is usually on the top of the seat tube, under the saddle. For conventional models (mountain, road), it is sufficient to measure the length of the seat tube from the carriage of the pedal assembly to the end of the upper tube in centimetres.

How to choose a bicycle by height and weight?

To select a bike by height and weight (depending on your body size and physical shape), look up the ratio of wheel size, frame and weight in the table. If your weight is high, it will be difficult to move around on the mountainous geometry of the frame (high tilt forward with weight transfer to the steering wheel). Choose from sturdy road or city models with a rigid front fork. A large loaded saddle and a vertical fit are better. Weighing more than 140-150 kg, you will need reinforced (with more spokes) road bikes and hiking bikes. We will help with the individual selection of the model!

The right balance between bike frame and height

Correct fit and health benefits are only possible if the bike frame is selected correctly. The spine and knee joints are lightweight and allow cycling at any age.
Avoid mistakes when choosing the correct slipform paver. You can not take the bike to the growth! At the current cost of budget models will be reasonable as the growth changes to choose a bike with the most appropriate frame size and wheel diameter.
