A steering system for a vehicle is provided. The steering system has a handlebar assembly and a steering column assembly connected to the handlebar assembly. The handlebar assembly includes a first conical surface and a first angular position limiter. The steering column assembly includes a second conical surface mated with the first conical surface, and a second angular position limiter configured to engage the first angular position limiter to limit an angular position of the handlebar assembly relative to the steering column assembly about a steering axis of the steering system. A compression element engages the handlebar assembly and the steering column assembly to compress the first and second conical surfaces against one another in order to fix the handlebar assembly to the steering column assembly. A plurality of linkages is configured to operatively connect the steering column assembly to at least one ground-engaging member of the vehicle.

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.
