ABSTRACT:
A riding apparatus includes a frame; a front wheel assembly, being rotatably mounted to the frame and having a substantially vertical front rotation axis; a rear wheel assembly, being rotatably mounted to the frame and having a substantially vertical rear rotation axis; a front steering link connected to the front wheel assembly; a rear steering link connected to the rear wheel assembly; and a pivoting device; the front steering link and rear steering link being connected to the pivoting device in such a way that the pivoting device translate an angular movement of the front wheel assembly around the front rotation axis into a deflection of the rear wheel assembly around the rear rotation axis in the opposite sense, thereby diminishing the steering radius of the riding apparatus; and a saddle mounted on the frame by a saddle pin, the saddle pin being rotatably mounted to the frame and having a substantially vertical saddle rotation axis, the pivoting device being fixedly coupled to the saddle pin, thereby enabling the steering of the riding apparatus by the saddle.
