Abstract
The proposed invention is a human powered cycle/vehicle which utilizes a reciprocating arcuate linear handlebar motion to operate a double acting asynchronous propulsion mechanism which imparts constantly proportional input versus output motion to its' surface engaging propulsion wheel(s). The propulsion mechanism contains a complex mechanism which causes both backward and forward motions of a set of handlebars to propel the machine forward. A drive-train clutch (52) may be included which enables the propulsion mechanism to be disengaged thus allowing the cycle/vehicle to be reversed and or moved (pushed) in either direction via its' surface engaging wheel(s) in isolation to the propulsion mechanism. A steering mechanism may also be attached to the handlebars (1) which are rotated clockwise to steer the machine to the right and anti-clockwise to steer the machine to the left.
