Battery electric vehicle vehicles, and a wide range of other devices. Certain manufacturers specialize in electric-powered "in plant" work machines. Three-wheeled vehicles include electric rickshaws, a powered variant of the cycle rickshaw. The large-scale adoption of electric two-wheelers can reduce traffic noise and road congestion but may necessitate adaptations of the existing urban infrastructure and safety regulations. From India, AVERA new and renewable energy company is going to launch two models of electric scooters at the end of 2018, with Lithium Iron Phosphate Battery technology. China has experienced an explosive growth of sales of non-assisted e-bikes including scooter type, with annual sales jumping
