Since converting a longboard or skateboard to electric will add significant weight, it is necessary to keep all of the components as light as possible to begin with. Carbon-fiber is an ultra-strong, ultra-lightweight composite building material, and it can be used to significantly increase the strength, and decrease the weight of a skateboard deck.
While it might sound daunting to work with carbon-fiber, it is actually very easy with some prior research (it is very similar to fiber-glassing). This deck has plywood supports for the trucks, and an integrated compartment for the electronics, which adds structural support and increases the clearance under the deck.
Additionally, by making your own carbon-fiber deck, you will be saving yourself a lot of money! An already-made carbon-fiber deck for electric skateboard will set you back about $500! If you buy in bulk, this deck costs only about $75, not including labor.
