Electric Skateboard is engineered with Lithium Battery pack and powerful driving motors, unlike the traditional
skateboard, the electric skateboard can support much moving much fast by itself with high speed;
When the users get tired , he/she can use the electric power and dive by the skateboard itself; It's
a kind of amazing experience for Extreme fans and other outdoor sport lovers.
With the development independent battery pack tech development, the users can disassembly the battery pack parts and
use the electric skateboards as the traditional one.
