The longboard deck used on the 1st and 2nd gen Boosted board is the Flex 3 Vanguard (38″/98cm), supplied and designed by Loaded Boards. It is rated for use by riders up to 250 lbs (113 kg).
The deck is intended for speeds between 0 and 25 mph (0-40km/hr). Due to it’s flexibility, it is not intended for higher speeds.
We tested our boards on a 25% grade with a 170lb rider. While the board is still capable of carrying heavier riders, the hill climbing ability will be reduced and the stopping distance will increase.
