Its the A-bike , the brainchild （脑力劳动的产物）of British inventor Sir Clive Sinclair, who made history in the 1970s by developing the worlds first pocket calculator.He described his new invention as the worlds smallest, lightest foldable bicycle. “My original thought was that if you could have a bicycle that was dramatically lighter and more firm than the ones that exist today, it would change the way in which bicycles are used, said Sinclair.

You require no extra energy to ride the A-bike and it can go up to 15 miles per hour （24 kilometres per hour）, he said.

Sinclair also invented the first pocket TV in 1984 and the futuristic C5 electric tricycle in 1985. He said he hoped the bicycle would attract common citizens, officials, campers or anyone needing transport for a short trip and he said the next step for the A-bike was to add an electric motor in a few years. 语篇解读普通的自行车人人都见过，可是你见过折叠以后像伞一样的自行车吗现在 有人发明了这种自行车。 1.
