A blow-up bike? Yes, wheely... and no, it doesn't need a giant puncture repair kit! Ford engineers design an inflatable frame so cycles can go in the car boot

become a whole lot more serious – as boffins have invented a blow-up bike

  엔지니어들이 자전거에 쉽게 바람을 넣을 수 있는 자전거를 개발했다.

바퀴에 바람을 넣는게 아니라 본체에 바람을 주입할 수 있는 프레임으로 되어있다.

따라서 바람이 빠지면 차에 반으로 접어 쉽게 넣을 수 있으며 빼서 세우면 낮은 압력으로

공기가 주입된다.

이 특수한 튜브 프레임은 방탄복에 사용되는 파라계 방향족 폴리아마이드 고강력 

케블라 섬유로 만들어진 7개의 고무 튜브로 구성되어 있으며 땅에 닿지 않는 한 

날카로운 물체에 의해 펑크날 염려는 없다.

The chance of getting a puncture has always been a headache for cyclists. But now the problem could be about to become a whole lot more serious – as boffins have invented a blow-up bike.

Engineers at Ford have designed the inflatable frame to make it easier to stow cycles in a car boot.

The bike has a traditional rigid steering column but the other parts of the frame – including the top tube, down tube and seat tube – are made from inflatable segments.

These segments consist of seven rubber tubes arranged in a petal shape enclosed in a larger tube made from Kevlar, which becomes rigid when the inner tubes are inflated.

Boffins insist that the Kevlar sheath – the same material used in bulletproof vests – would be tough enough to stop the inflatable sections from being punctured. 

And as the frame does not touch the ground, they say it would be less likely to come into contact with sharp objects anyway.
