The bicycle could be simplified eliminating the chain and gears completely by locating the pedals on the back wheel.
The bicycle minimalist design will include a steel frame consisting of two bars between the wheels as well as diagonally placed forks, which will leave only a small gap between the front and back wheels. The rear steering and lightweight will offer new maneuverability options and the simplified design will be easy to maintain.
The small size of the bicycle will also make it easier to transport through stairwells, hallways and other tight spaces.
