Watch Out! Meet the World's Fastest Bike

The newest offering from Aerovelo promises to be the world's fastest bike. The Eta bike, with a human power speed of 89.59 miles per hour, has already brokeb a world record. Last Sept. 17, Eta won the World Human Powered Speed Challenge held in Battle Mountain, Nevada. Todd Reichart, Aerovelo's co-founder, rode Eta to victory.

The Canadian engineering company designed Eta to be lightweight, only weighing about 55 pounds. The makers use computational fluid dynamics and optimal aerodynamic shaping techniques for creating this fast bike, according to Aerovelo.

In quest for ultimate efficiency, Aerovalo's unusual design of Eta will not fail to catch an eye. This recumbent bike might look uncomfortable to ride on, but its design has already been proven-tested to maximize the new improvements made.

Eta's bullet-shaped outer housing is made of carbon fiber helps minimize rolling friction and wind resistance.This outer shelling drops down the drag more than 100 times than any streamlined cars. Eta bike had 198 watts of pedal power at 90km/hr. The bike had razor-thin tires with dual SD cameras and on-screen display.

"This was another massive leap in an event that had been fighting for 0.16 km/h (0.1 mph) gains over the last decade," wrote the Aerovelo team on its company blog. "Breaking into this new range of speeds, Eta has truly earned its name and its title as the world's most efficient vehicle."

To achieve insane speeds, an Eta rider should be athletic and fit. Other important issues on Eta are minimizing friction and wind resistance. Without a rider, Eta weights 25 kilograms (55 pounds) and is built with a very low center of gravity and handmade tires.

Aerovelo co-founders, Todd Reichert and Cameron Robertson, are fond of racing bikes since 2009. They already built two innovations: Atlas, world's first human-powered helicopter in 2013, and Snowbird, world's first ornithopter in 2010.
