Marking based on the diameter of the wheel. Generally speaking, 12 inches, 16 inches, and 20 inches refer to the diameter of the wheel, and inches refer to inches, and each inch is equal to 2.54 centimeters. 2.14 inch 18 inch is not a universal standard The global standard for bicycles is only 12-inch, 16-inch, and 20-inch products, while 14-inch and 18-inch bicycles are actually a positive “innovation” made by domestic manufacturers based on market needs. This is also the reason why some international brands do not have intermediate models such as 14, 18. Due to the height of the seat and the adjustable handlebar position, usually a bicycle can meet the requirements of many different age groups. But because baby strollers of different sizes not only have differences in height, but also in length, handlebar width, torque, etc., so it is best not to choose too large a model. Our suggestion is to choose a model that is centered and larger.

Paint process 1, First of all, the baking paint needs to put putty on the panel door as the bottom layer of the spray paint. Apply three times of primer and four times of top coat on the substrate. Each time the paint is applied, it is sent to a dust-free and temperature-controlled baking room for baking.
Paint process 2, After leveling the putty, wait for the putty to dry, and polish and smooth the surface of the paint door. Compare the light to see if there is orange peel on the surface of the painted door. The surface of the door panel should be free of lines and orange peel. Touch the edges and corners of the painted door panel with your hands to see if they are smooth and flat; observe whether the color of the edges and corners is the same as the color of the door panel.
Paint process 3, Then spray the primer 3-5 times, and after each spray, polish the paint with water sandpaper and abrasive cloth. After finishing, touch the surface of the painted door with your hands to see if there are dust particles and air bubbles. The surface of the painted door panel should be flat and smooth, free of particles, and no abnormal touch to the touch.
Paint process 4, Finally, spray 1-3 times of bright topcoat, and then use high temperature baking to cure the paint layer
10G 14G represent the models of spokes. The models are roughly subdivided into 8G, 9G, 10G, 13G, 14G, 15G, etc. according to the diameter. Spokes of different diameters have different advantages. Children’s bicycles generally use the above two models of spokes.
