Bicycle seat adjustable during ride

Abstract

An oscillating pedal bicycle in which the downward force exerted by a rider is converted from the oscillating motion of the pedals into a unidirectional rotation of the drive wheel. The oscillating motion of the pedals is transmitted by flexible tension members to a conversion mechanism for converting the linear motion of such tension members into the rotary motion of the drive wheel. Maximum utilization of the motive power of the rider is achieved through the use of a quick-release, variable position body restraint and a variable height seat, both of which are adjustable while the bicycle is in motion, while maximum transfer and conversion of such motive power is achieved by an improved pedal return and tension member rewind mechanism and an improved drive mechanism. Pedal stabilizers, rotatable foot restraints and foot actuated lever control mechanisms are provided to maximize motive power and efficiency.
