About Sada Bike

The idea of a folding bike has undertaken numerous studies that focus on reducing the weight and dimensions which have led, however, to realize too small sized bicycles. They have a small frame and wheels at the expense of stability, for the sake of compactness and portability during transport. The minimum size of the frame, in fact, penalizes the rider position while driving and the small size of the wheels significantly are affected by variations in terrain. On the other hand, the traditional bicycles, avoid these problems, but the rigid chassis makes them inflexible during transport on public transport.
The objective of Sada Bike is to have a cycle with standard dimensions ( wheels 26 “) and have a small package during transportation. The wheels have no spokes, the minimum size in closing, foldable with a single movement, the packaging container can also be used as a backpack, are innovations of this project.
The starting point of this research is the study of art that starts from an overview of the urban individual mobility to reach, then, the folding bicycle.


It has been adopted a system of anchoring of wheels composed of small wheels held by a small frame and a specific quick clamping device. They allow you to fold the bike quickly and easily, using its special package like a trendy backpack.
Some studies have been done about characteristics of both components of frame and wheels to analyze their behavior during the application of loads (interference and FEM analysis). In conclusion, the project may pave the way for a new system of mobility outside the classical schemes, widely accessible and easily transportable. Personal style and extreme versatility give dynamism to the traditional bicycle, the subject increasingly required in this environmentally friendly age.



Packed in a backpack

This hubless bike features a frame that folds away for maximum portability. It can even be packed in a regular-sized backpack, with others objects!

No spoke!

The design focuses on the bike’s space-saving advantages. Unlike most bikes, which usually get their strength from the tension in the spokes, the strength of the Sada Bicycle is put into the rim. Sadabike has spoke-less wheels!


Sadabike is a hubless bike which can fold up to the size of an umbrella with one movements, making it perfect for commuters who need to make lots of short trips.
