The disclosure is related to a transmission cable, and more particularly to a set of cable connectors for electric motor vehicle such as an electric bicycle or an electric motorcycle.
In recent years, electric bicycles, electric motorcycles, and electric cars are popular clean technology products; among them, electric bicycles and electric motorcycles are important mobile vehicles for urban short-distance transportation. Generally, the electric bicycles and electric motorcycles need specific transmission cables for signal and electrical power transmission, and require relatively large current during start or acceleration process, so the current transmission cable must be a thicker cable which is able to tolerate a relatively large amount of current.
