The electric tricycles currently on the market, also called “flat three wheels”, have many brands, but their forms and structures are basically the same in all parts. The quality of electric tricycles is different only because of differences in materials and manufacturing processes.
Since the electric tricycle is a heavy-duty vehicle, its material requirements are also high. Generally speaking, a good electric tricycle skeleton (tripod) is made of seamless steel pipe. Because of its high strength, it has high strength and is not easily deformed. The electric tricycle should be easy to lift, labor-saving, flexible, and no abnormal sound and smooth.
