A freeboard is kind of specialist skateboard designed to closely simulate the behavior of a snowboard.
It has 6 wheels, two spring locked center wheels, and four slightly raised conventional wheels. The central axis wheels are able to turn freely in all directions, which allows the freeboard to slide laterally as long as no other wheel touches the ground. By exerting some pressure on the edge wheels, the freeboarder is able to control the board. The central wheels thus mimic the deck of the snowboard, while the outer wheels mimic the two steel edges.
Decks are constructed with a seven ply cross-laminated layup of Canadian maple. Modern decks vary in size, but most are 7.5 to 9 inches wide and usually between 29 and 36 inches long. Bindings are used to provide more control over the board and allow the rider to exert more pressure on its edges. As on a snowboard, the rider is able to perform both carve and slide turns.
The price range for a new and decent Freeboard range from $180 and up. How you customize the deck and the cost of wheels impact the price.
