Video: British man creates jet-powered bicycle Colin Furze, 32, had the idea for this latest invention after saving his friend's mother's cycle from the scrap-heap. By attaching a crude jet engine to the back of the old Raleigh bike and extending the frame to put the rider a safe distance from the heat, the 32-year-old managed to reach speeds of 50mph on-board the modified bike that he has named "Norah." Footage of his test ride has been viewed just under 150,000 times on YouTube since it was uploaded on Thursday. The speed-loving self-styled "garage inventor" also lays claim to Guinness World Records for the world's longest motorbike and the world's fastest mobility scooter.
