If you want to ride an unique electric skateboard which perfectly fits to your weight, riding skills and style, we suggest you look into an "electric skateboard kit" also called "electric skateboard conversion kit".
While there are some cheap kits available on the web, we are only looking at high class electric skateboard conversion kits in this article.

The reason why we are only looking into the advanced electric skateboard conversion kits is that the price is depending on the quality of the motor, battery, remote control and how well they fit together. If you use cheap components, you will very fast feel the frustration of lack of power, speed, distance and usability.

We found 2 promising kits which are selling between 700 and 1,700 USD. So as you can see price is not the point as you will get complete electric skateboards for this price.
There is the Kickstarter project Mellowboards from Hamburg which charges 1,700 USD and the Funky Drive team with its X3 ONAN which sells for 700 USD.

The X3 ONAN Funky Drive is coming with two 600 watt brushless motors which are supposed to serve riders up to 275 pounds with a speed of 12 to 18 miles per hour and a distance up to 15 miles.
The Mellowboards kit also comes with two in-wheel motors but promises up to 24 mph and a grade up to 20 degrees.
We will review both electric skateboard conversation kits once they are available.
