Abstract
Abstract A dual-footboard scooter in a tricycle format having a front wheel or ski coupled to a steering post passing through a steering column to join a steering handle and a bifurcated frame extending rearwardly from the steering column forms two branches, extensions of which each support a rear wheel or ski, respectively. In operating the scooter, the rider grasps the steering handle, rests one foot on either footboard and swings the other foot extending through the extended free space between the footboards and bifurcated frame, making pushing contact with the ground or snow to propel the scooter.
