The invention relates to a board inspired by the common skateboard, but technified such as to roll, rotate and jump over the greatest variety of surfaces without requiring a motor, ramps or special tracks. A spring-mounted flexible platform, supported by a central roller shaft, serves as a drive means, converting the bending generated by the weight and force of the user thereon into rotational energy, adding speed, using the free-wheel system. The invention is capable of rotating up to 360°, operating as a jumping catapult for figure skating and reducing impact on the muscles by cushioning the bearing. The invention is safer because it includes a brake, a rotating front wheel for greater agility, a light refractor for greater visibility and a means for adhesion to the user. The invention provides pleasant exercise to prevent apathy and obesity, as well as clean transport for kids.
