Abstract
The present invention generally relates to a propulsion device and method of use of the propulsion device that propels at least one user equipped with at least one friction-reducing device. The propulsion device typically comprises a motor, a drive train, and a traction device attached or incorporated into a frame. At least one user is secured to the device by straps that engage the user at a waist level or shoulder level interface. The user may direct the propulsion device by acting upon the handlebars that are adjustably attached to the frame of the propulsion device. Moreover, multiple users using multiple propulsion devices can engage in social group or competitive activities. The propulsion device offers the versatility of being able to traverse numerous forms of terrain while using a variety of friction-reducing devices.
