пассажир трехколесный велосипед

passenger tricycle three wheel motorcycle(laobancanke) A. Its framework is a widened one of the integrative type. The flexible coupling technology is adopted in connecting the engine and the frame(The intellectual property right of the flexible coupling technology belongs to our company ). The bumper is firm and the gravity is low. All these are enough to promise the motorcycle a strong cushioning capacity and a steady running. B. The surface treatment of the frame adopts the process of ball blasting, the process of and the process of cathode electro-coating, therefore the appearance is elegant and the adhesion of coating film and the corrosion resistance are strong. C.The advanced process of roller forming is adopted in producing the carriage (The carriage is made up of the parts of the integrative type), so the carriage has a strong durability and a strong bearing capacity. The surface treatment of the carriage adopts the acid pickling process, the process of phosphating, the advanced process of cathode electro-coating and the OMEGA electrostatic painting technology. Therefore the adhesion of coating film is strong. Consequently, the appearance quality of the motorcycle is enormously enhanced.
