Meet the Boosted Board: an electric, motorized skateboard that provides you with a fun experience outdoors. You can call it the skateboard of the future or anything you like, but this is easy to learn and offers adjustable power. You can change mode to control speed and torque limit and use its handheld Bluetooth enabled thumbwheel to control your experience.
Boosted Board offers regenerative braking. It can go as fast as 20mph for safety. The board is rated for a 15% grade but you may be able to go up steeper hills depending on your weight. The board goes for 6 miles on a full charge. Keep in mind that you need to be below 250 lbs to use this. Boosted Board is not waterproof, so choose your adventures carefully. Not a cheap skateboard but looks quite fun.
