Meet the Mellow electric drive: a nifty device that turns any normal skateboard into an electric skateboard. Mellow can be mounted on any skateboard, weighing only 5.5 lbs. It provides you with 4 riding modes (Rookie, Eco, Pro, and Endless). It is water and dust-proof. There is even a USB-port to charge your phone.
The Mellow electric drive has 2 in-wheel motors to provide you with a more fun skateboarding experience outdoors. It lets you reach a top speed of 25 mph. The battery provides you with a range of 10 miles. The Mellow Remote gives you control over your electric skateboard. Yet another interesting Kickstarter project.
