ABSTRACT:
A high performance two-wheeled human-powered vehicle propelled by a reciprocating thrust motion of the operator. An elongated bicycle frame has a gliding chest rest and slidably mounted trolley on an upper frame member, longitudinally positioned between a drivably mounted rear wheel and steerably mounted front wheel. Foot rests, to provide support for forward thrust of the body, are mounted on either side of the rear wheel. The foot rests and chest rest and trolley allow the operator to lie forward over the frame, between the wheels, and reciprocate longitudinally with the operator's upper body supported by the guiding chest rest. Attached to the trolley is a drive assembly that includes a reciprocating chain travelled around a gear, Ends of the reciprocating chain are fixed to the frame and corresponded with a biased cable, spring and pulleys; so that forward motion of the trolley causes the chain to drive a conventionally mounted sprocket, cog and continuous chain assembly.
