  • Golf-bag carrying vehicle
    Patent number: 10450027
    Abstract: A golf-bag carrying vehicle is an apparatus that assists a user in transporting their golf bag by either manually push-kicking the apparatus or motorizing the apparatus. The apparatus includes a pair of idle wheels, a stabilizing wheel, a frame, a steering mechanism, a handlebar, and a footboard. The pair of idle wheel arranged at the front end of the frame and the stabilizing wheel arranged at the rear end of the frame are configured into a tricycle configuration, which creates ample space in the center of the apparatus for a rider and/or a payload. The steering mechanism and the handlebar allows a user to steer the apparatus in a desired direction. The footboard allows the user to selectively ride on the apparatus or to manually assist the movement of the apparatus by push-kicking.
