The invention is a bicycling device and method of use thereof, whereby muscle power can be more efficiently transferred from the cyclist's upper-extremities (arms) to the conventional footpedals via the cyclist's lower-extremities (legs) without need of mechanical contrivance and associated drain on fractional human-power capability. The device is attached proximally to the knee region as a method by which a cyclist may obtain a firm manual handhold, whereby the cyclist can grasp the device with his hand and proceed to exert appropriate downward-thrust or upward-thrust (during up-stroke using shoe/pedal-cleats) supplied from upper-extremities according to the regular cyclic rotation of the associated footpedal. Since upper extremity thrusting is applied directly through mechanism of the cyclist's own lower extremities, the need for manufactured mechanical contrivance and its associated weight penalty has been averted. Hence, the cyclist can combine additional power from the upper extremities instantly as needed, while realizing the benefit of exercising muscles in all four extremities as well as in torso. The device may be made integral with the cyclist's apparel or otherwise secured via leg-associated locative constrainments, whereby the device is basically a component of the cyclist's personal gear, not of the bicycle.
