A new and unique wheeled vehicle comprising a unicycle-like device. The device employs the same general elements as a unicycle including a single large drive wheel, a pair of pedals, a seat, and a pair of forks to support the seat. Attached to the rear of the device is an additional set of support wheels. The support wheels are attached through a support frame which extends generally rearwardly and downwardly from the center of the drive wheel. The support wheels are attached to one another by an axle, which is in turn attached to the support frame in such a manner that the support wheels pronate and track through turns as the drive wheel is turned to the right or left. Under normal conditions the support wheels remain on the ground at all times. This device provides the rider with additional longitudinal stability without adding a significant increment of lateral stability.
