Collapsible hydraulic polycycle

Claim 1

In a pedal operated polycycle having at least three wheels and having pedal means, a polycycle comprising: (a) a front-to-rear mainframe; (b) at least one rear axle and associated wheels, journalled within a rear wheel assembly depending from said mainframe; (c) handle bars depending laterally outwardly from a steering column; (d) a front wheel assembly integrally depending from a front end of said mainframe and secured to said steering column; (e) a front wheel journalled upon a front axle of said front wheel assembly; (f) a seat secured on said main frame between said front and rear axles; and (g) means for the selective, telescoping, partial collapse of said front-to-rear mainframe; (h) a hydraulic cylinder in fluid and pressure integral communication with piston means depending from said pedal means; (i) a hydraulic line in substantial co-alignment with said main frame, and input of said line in hydraulic communication with said cylinder; and (j) rear wheel drive means securing rotational relationship with both an output of said hydraulic line and a tangent surface of said rear wheels, where upon, upon reciprocation of said piston means, as by a pedalling action applied to said pedal means, a hydraulic amplification of pressure resulting from said pedalling action will be transmitted through said line to said drive means, thereby applying a rotational force to said tangent surface of said rear wheel causing a resultant rotation thereof and a consequential transactional movement of said polycycle.
