Generally speaking, children's bicycles are classified according to the wheel size, and there are three types of children's bicycles: 12 inch, 14 inch and 16 inch. There are bigger ones, of course, but they are no longer children's bikes. And 12 inch, 16 inch, 20 inch refers to the diameter of the wheel, inch refers to inches, each inch is equal to 2.54 cm, so the wheel diameter of the 16-inch bicycle should be 40.6 cm, the wheel diameter of the large 29-inch bicycle should be 73.7 cm.

There are also some labels based on the height of the frame. In addition to bicycle models based on wheel diameter, there is also a saying based on frame height. Frame height refers to the length from the bottom of the pedal to the top of the seat pole. The 15-inch bikes under this label are usually suitable for children between 150 cm and 165 cm in height.

Whether in terms of wheel diameter or frame height, the bike type is mainly used to indicate the size of the bike. Of course, bigger bikes are usually longer and have wider handlebars.
