Currently under the influence of the energy crisis and global warming, alternative energy – electric power is the best replace methods. Development of electric cars is the focus of the industrial countries in the world, With the development of electric cars, more and more developed electronic components and advanced materials technology, efficiency and volume gradually to meet modern requirements. The modular design of scooters, the use of self-designed torque sensors, special brushless motor and electronic control circuit board, integrated into a purpose-built chassis, placed on the bike below, in order to achieve high endurance, effort, keep feet Riding riding fun.Experimental research on flexible pressure is a linear relationship between perception of film, special brushless motors and brushless motors for general industrial use of the comparison, the module power and tension than riding on the experiment to test the feasibility of modules.
