The combination, with a skateboard comprising a platform with at least two pairs of wheels connected thereto on one side thereof, of: 1. Friction means pivotally supported by resilient members on the underside of said platform above one pair of wheels; 2. An activation lever attached to said friction means in such manner that said friction means is caused to come in contact with said wheels upon depression of said lever, and to be removed from contact upon elevation of said lever; 3. Hinge means pivotally attaching an end of said lever to said platform of said skateboard; 4. Spring means holding said lever normally at an angular relation to said platform, with the end of said lever not attached to the platform at a distance from the platform; and 5.
