There is no difference except the appearance and logo. Seven or eight years ago, British RT found an OEM in China (a bicycle parts factory in Hangzhou). Later, the main engine factory registered the RT trademark in China, and then the factory was divided into several similar brands, including Ruituo RC3 XRXRXRC3 and so on. A small brand with a few hundred dollars is not durable. Go to a treasure to find an expert in wheel weaving (heavy-flavored bicycle wheels, Jie Jun Brothers Wheel Workshop, etc. ), and make your own wheel hub 500-600 or 700, and what is cr3, lightweight, tolerance, strength, rigidity, flower drum grade and so on. Generally, those under 500 are not good or have low strength, low durability or heavy weight, and their feet are seriously dragged when riding.
