       About the Dimensions of Bicycles

       1. Marking based on wheel diameter. Twelve inches (inches), sixteen inches and twenty inches are the diameter of the wheels. An inch means an inch, which is equal to 2.54 centimeters per inch. Therefore, the diameter of a 16-inch bicycle's wheels should be 40.6 centimeters, and that of a 29-inch bicycle's wheels should be 73.7 centimeters.

       2. Marking based on frame height. In addition to the bicycle model based on wheel diameter, there is also a frame height. The frame height starts at the bottom of the pedal and ends at the top of the seat pole. Common adult bicycle models range from 15 inches to 22 inches. A 15 inch bicycle is usually suitable for a height of 150 to 165 centimeters, while a 22 inch bicycle is more suitable for a height of 185 centimeters or more.

       Because of the adjustable seat height and handlebar position, a bicycle can usually meet the requirements of different age groups. For example, 16-inch children's bicycles can be used for babies with a height of 105CM-135CM, 18-inch children's bicycles can be used for children with a height of 115CM-150CM, and there is a 20-centimeter intersection between the two models (115CM-135CM). That is to say, we can buy 16-inch or 18-inch bicycles for 115CM-135CM children. How do we choose?

       Because bicycles of different sizes differ not only in height, but also in length, handlebar width and torsion, it is better not to choose too large models. Our suggestion is to choose the larger model in the middle. For example, although a 16-inch bicycle is suitable for babies with a height of 105 CM-135 CM, it is recommended that only children with a height of 110 CM or less should choose a 16-inch bicycle.
