關於 Sada Bike 摺疊單車

Sada Bike係一款採用26吋車輪嘅無轂摺疊單車。大車輪令騎乘姿勢舒適，同標準單車相近。每個車輪由三個支點固定：前支點設喺擋泥板結構之中，後支點就位於輪圈內側。鏈條將動力傳送至下方嘅小輪，再將扭力傳遞到後輪圈。車架圍繞單一中央支點轉動，令整個結構只需一個動作就可以摺合成接近雨傘大小嘅形狀。摺疊後嘅單車可以孭喺膊頭上，亦可以好似手推車噉拖行。

新聞資料包

由設計師提供嘅製作人員名單、團隊成員同技術詳情。

獨特屬性: 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.
尺寸同包裝: 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
標籤: Hubless, Foldable, Trolley, Umbrella Bike
生產技術: 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.
設計挑戰: 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.
研究: 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.
靈感: 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
項目時長: 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).
操作流程: 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.
