Scottish racing cyclist Graeme Obree has made modifications to his supine recumbent, which is made from recycled materials, in a bid to break the human-powered land speed record. Obree made the bike, which is named Beastie, out of recycled materials in his kitchen. The low-slung bike is extremely aerodynamic, and it requires the rider to lay head-first inside a a Kevlar and fiberglass shell.
According to Humans Invent, who have been following Obree’s attempt, the world famous cyclist took his design back to the drawing board after deciding it wasn’t slippery enough. The design now sees “the front section rounded”, so that it “pulls the air back in again with the least amount of energy is to have a laminar (non-turbulent) flow over the sides of it.”
There are other problems hampering the Beastie. In order to get going, Obree needs a push, but the new shape has proven difficult for his helpers to hold onto due to its new sleek design. “I wanted to go at a great speed right away but the guys couldn’t launch me,” said Obree. “Back when I tested it at Machrihanish airport, I only needed one person to launch it so I assumed it wasn’t that hard to keep me upright and push me in a straight line but because it’s now all slippery and fish-shaped it’s hard for them.”
Obree hopes to break Sam Whittingham’s 83mph record. While it is uncertain whether he’ll achieve this, he is expected to break Jason Queally’s British record of 63mph. Beastie was constructed from a steel frame, covered with a Kevlar and fiberglass shell, which Obree made in his kitchen using recycled parts.
