Scarpar's all-terrain powerboard, and now it's just about ready to hit the streets, or mountains, or whatever. The Australian startup is currently accepting reservations for its surprisingly powerful electric skateboards -- now in two flavors. Scarpar's Model X comes equipped with two 1.5-kilowatt DC Motors and tops out at 28MPH, while the Model S offers two 750-watt motors and hits 18MPH. You can reserve one now for $500 or $600, depending on how much power you want under your feet, but be prepared to shell out either $2,800 or $3,800 when it's finally time to buy. Scarpar expects the things to ship sometime in December, so don't go making any summer vacation plans for you and your new off-roader just yet.
