The Design
About Sada Bike Baaskiil Laalaabma
Sada Bike waa baaskiil laalaabma oo aan lahayn xudun (hubless) oo leh giraangiro dhererkoodu yahay 26 inji. Giraangiraha waaweyn waxay taageeraan fadhi raaxo leh oo fuulis ah oo la mid ah kan baaskiilka caadiga ah. Giraangir kastaa waxaa lagu hayaa saddex meelood: meelaha hore waxay ku dhex jiraan qaab-dhismeedka daboolka giraangiraha (fender), halka meelaha dambe ay ku dhex fadhiyaan giraanta gudaheeda. Silsilad ayaa dhaqaaqa u gudbisa giraangir hoose, taas oo awoodda wareega (torque) u wareejisa giraanta dambe. Qaab-dhismeedka baaskiilku wuxuu ku wareegaa hal bar dhexe oo tiirar ah, sidaas darteed dhismaha oo dhan wuxuu ku xirmaa hal dhaqdhaqaaq isagoo noqda qaab u dhow cabbirka dallad. Baaskiilka la laalaabay waxaa garabka lagu qaadan karaa ama waxaa loo dhaqaajin karaa sida gaari-gacmeed (trolley).

- Unique Properties
- The SadaBike have 5 strategic points:
1) Hubless bike.
This means: Innovative Design and very good ergonomics and comfort.
2) Hubless and foldable bike:
It has a special fulcrum in the center, all the frame folds, into a compact shape, similar to an umbrella.
3) Foldable with a single movement.
4) Portable on Shoulder:
The small size has the advantage of carrying the bike on the shoulder.
5) Portable as a Trolley:
The backpack presents a central hinge that allows the expansion in the trolley mode. - Dimensions & Packaging
- Sada Bike measurements:
In «open version» Sada Bike is like a «normal» 26 inch bike: 1640mm; 980mm; 530mm
The dimension of only the frame, is like an umbrella and included rims, overall measurements are: 700mm; 600mm; 280mm - Tags
- Hubless, Foldable, Trolley, Umbrella Bike
- Production Technology
- The parts of this bike are in aluminum alloy (7075 Ergal) made by CNC process. The next prototype and the production will be made in Ergal and carbon fiber.
- Design Challenge
- The bicycle without spokes was a challenge between innovation and design. The search for the perfect circle and the study of the laws of physics, yet the commitment, perseverance, with a certain amount of obstacles and falls have made it possible to operate the circle without rays, without constraint to the hub .. and again ... the search of technical and industrial partner, led me to finalize an essential design with extreme innovation.
- Research
- The result of the project is a 26 inch foldable bicycle with a minimum size when folded (the frame dimension is barely the size of an umbrella) for hand-transport.
Sada Bike, despite the sizes of its wheels and the total absence of hubs and spokes, when folded, is the lightest and least cumbersome foldable bike on the market as it can be transported in an elegant trolley. Other foldable bikes have tiny wheels and frame enhancing manageability at the expense of stability and safety. - Inspiration
- Demanding mobility-related service has its consequences on society: street congestion of metropolitan hubs is the everyday challenge commuters have to face and it is a source and stress and delays.
«You never change things by fighting against the existing reality. To change something, build a new model that makes the old model obsolete.» R.Buckminster Fuller
Promoting and enabling virtuous behaviors for smart mobility, intermodality, sustainability for the environment are the values driving Sada Bike - Project Duration
- The main exhibitions are:
SMAU Torino (Torino Italy 05/2014); Napoli Bike Festival (Napoli Italy 09/2014); Forum del Design (Milano Italy 10/2014); TEDx Bologna (Bologna Italy 10/2014); Bike to the future: Design Museum Gent (Belgium 10/2016), Bloomfield Science Museum (Jerusalem Israel 05/2017), Universum Bremen (Germany 04/2018), Citta della Scienza (Napoli Italy 4/2019), Science and Technology Museum (Ottawa Canada 04/2020), Franklin Institute (Philadelphia USA 04/2021). - Operation Flow
- The frame is composed mainly of 4 parts similar to a scissor front and a rear. Each wheel is supported in 3 points: the front ones are inserted in the fender structure, while the rear ones are allocated inside the rim.
The bending system has a central fulcrum around which the front and rear parts of the structure and allows it to close the whole frame in a very compact way.
The Sada Bike has a change in the lower wheel that transmits the motion, which allows multiplying the speed of 3 times. The chain then transmits the motion to the lower wheel that transfers torque to the rear rim. - Patents
