Yuneec Technology has brought the aviation technology to the streets and displayed E-GO Cruiser[available for pre-order] in CES 2014. A 400W motor gives the robust strength to the longboard and turns it into a roadster. It is powered by a 240V/110V declarable battery and comes with an electric plug. The rider can achieve the top speed within 15 feet. The board can be controlled with a remote or an iPhone app. You can ride on it with top speed of 12mph and can travel up to 18 miles in one fully charged go. You can gain speed by sliding the controller forward and make it stop by sliding backwards. Rock the streets with E-Go Cruiser.
