Abstract
Abstract This invention relates to a front wheel resilient suspension system for a chainless bicycle where a horizontal bar member extends between a main bar member located under the bicycle seat to a horizontal bar connector mechanism which is resiliently mounted to both the horizontal bar member and the handlebar of the chainless bicycle. A buckle mechanism located on the horizontal bar member allows for pivotal displacement of the handlebar with respect to the bicycle seat and provides for a responsive displacement of the center of gravity of a bicycle rider on rough terrain which adds to the cushioning effect and the comfort of the bicycle rider.
