Mellow is the first mountable electric drive that turns any normal skateboard into an electric skateboard – within minutes. The Mellow Drive is the first ever drive system for skateboards that can be mounted under pretty much any deck.
You just pick any of your favorite and turn it into a full on riding machine. I have always dreamt of something like this ( well it was mostly in hoverboard form but this comes close enough) and now a team in Germany is making it a reality.
