A vehicle for transporting a rider includes a platform for supporting the rider and at least one skate truck coupled to the platform and including a housing. An axel included in the skate truck extends through the housing to support a wheel having a rotational relationship with both the housing and the platform. Motive power rotates the wheel relative to the platform a free-wheel bearing includes first portions coupled to the wheel and second portions coupled to the motive power. The second portions of the bearing have a fixed relationship with the first portions of the bearing when rotated in a first relative direction, and have a free-wheeling relationship with the first portions of the bearing when rotated in a second relative direction opposite to the first relative direction. When the motive power comprises a motor, portions of the platform can be adapted to receive a battery.
