An extended bicycle frame (FIG. 2), (FIG. 3), (FIG. 4) and (FIG. 6) utilizing a top tube extended directly or at an angle rearward (12) from a forward top tube (10) at an intersection of a seat post (16) to a rear fork (14) connected downward to an axle (40) in combination with a harness apparatus (62) with front and rear male connectors (26) securable to forward (10) and rearward top tube (12) movable female connectors (24) providing a cyclist with a point of resistance at the shoulders or upper body (32) including a rotational/elevational handlebar (34). A cyclist, by either standing (FIG. 4 ) or leaning forward in various degrees (FIG. 2) (FIG. 3) is capable of efficiently implementing Newton's Law of Physics, For every action there is an equal and opposite reaction. An extended bicycle frame in combination with a harness apparatus, provides a means for a cyclist to exert a maximum force of his legs to said point of resistance (32) and directly translate said maximum force in an equal and opposite direction to the pedals (36) with a minimum of effort and discomfort. In previous art, a cyclist, without a harness contraption, on a normal bicycle (FIG. 1), (FIG. 5) in a usual position (FIG. 1) was limited to said weight of a cyclist plus the strength of his arms, elbows, wrists and hands in directing a force to said pedals. When prior art utilized a harness contraption on a normal bicycle, a cyclist in the usual position, exerted such extreme force vectors to the lower back area (42) as to present a real danger of injury, thereby limiting the time and distance he could travel comfortably. The capability of exerting a maximum force by means of said extended bicycle frame (FIG. 6) in combination with a harness apparatus (62) allows a cyclist the option of utilizing an enlarged sprocket (FIG. 8), with or without a deraileur (60), for even greater power and speed without additional effort and minimal force directed to the lower back (42).
