A compound drive foldable bicycle consisting of a bicycle in an unfolded state having a length between the outer edges of a front and a rear wheel that is divided into three sections such that the rear wheel is swung up and down into the unfolded and folded state on a second drive shaft that serves as a pivot point, while the front wheel is horizontally swung into the folded and folded state via a foldable locking mechanism that serves as a pivot point and which is positioned on the down tube (or the top tube) and, furthermore, situated within the circumferential perimeter of the chainring. As a result, the rear wheel is postured at the lower extent of the chainring and front wheel is postured at the lower extent of the saddle when the bicycle is in the folded state such that it is of the smallest and most flexible physical dimensions to save space and reduce packaging material requirements, thereby facilitating storage, placement, and shipping.
A compound drive foldable bicycle comprising a bicycle in an unfolded state having a length between the outer edges of a front and a rear wheel divided into three sections that provides for swinging the rear wheel up and down for unfolding and folding via a first driven chain cog and a drive shaft serving as a pivot point and thereby posturing the rear wheel at a lower extent of a chainring;
