Sir Clive Sinclair, inventor of the fabled C5 electric tricycle, road tests the revolutionary Segway scooter… and announces secret plans for another pioneering new personal transporter.

When it was unleashed on an unsuspecting public in 1985, the Sinclair C5 was the last word in futuristic transport. Ten months, and £6m of investment, later it was consigned to the commercial scrapheap.

Now its inventor, Sir Clive Sinclair, is working on a “C6” – a top-secret follow-up to the ill-fated C5, to be unveiled next year.

Sir Clive broke the news of his intriguing new invention while road testing the revolutionary new Segway scooter for BBC News Online.

In America, the Segway is becoming the method of transportation du jour for workers who would otherwise have to walk long distances. Postmen in Florida, police officers in Boston and staff at Disney World are among those to have been issued with the upright electric scooter.

Even George Bush took a ride on one, although any White House endorsement was somewhat undermined when he was catapulted over the handlebars.

Chris Grindley, chairman of Planet Moto – the company which started importing the US-made Segways into the UK in February – cautions they are easy to ride, but demand some confidence from the user.

Bearing this in mind, Sir Clive fared well on his first go on the Segway, and declared himself highly impressed.
