133,78 kmh en pédalant sur un genre de vélo ... sans dopage

Précédent record sur un vélo couché avec les pieds devant, là, toujours couché, mais tête la première.

Oui oui ... drôles de pédales ... mais ça a l'air d'appuyer fort !

World Record Bicycle Speed 83.13 mph 133.78 kph Human Powered Team Delft Sebastiaan Bowier VeloX3 filmed by Lynn D Lehman a local resident of Nevada. For three years, a team of Dutch university students from Technical University of Delft and VU University Amsterdam have come to the World Human Powered Speed Challenge (WHPSC) located on Nevada Highway 305 south of Battle Mountain, Nevada. They built three different two-wheeled streamlined recumbent bicycles, the VeloX1, VeloX2 & VeloX3, each of which was pedaled over 80 mph by Sebastiaan Bowier. Each year they won the competition 2011, 2012, 2013. Their three-year effort culminated on Saturday evening, September 14, 2013, when Sebastiaan pedaled the VeloX3 to a new Flying Start 200 meters world record with a time of 5.382 seconds, which equates to 83.13 mph or 133.78 kph. Human Powered Team Delft became the first student-team since 1979 to hold the top overall speed record. Human Powered Speed records are sanctioned by the IHPVA International Human Powered Vehicle Association. This broke the existing world record of Canadian Sam Whittingham who set a mark of 82.82 mph or 133.28 kph set in 2009. Sam held the top speed record since 2000, a 13-year reign. Each of his world record setting Varna streamliners was built by Georgi Georgiev. Racers pedal one at a time along a 5.5 mile stretch of the highway gaining speed. The road slopes by less than 2/3rds of one percent over its length, which equates to a drop of about 130 feet over the 5 mile stretch. This is the maximum amount of downslope allowed by the rules, a rule created since no roads in the world are truly "flat" over a long distance. The rules also require that the wind be blowing less than 2 meters per second (about 4.5 mph or 7.2 kph). The vehicle can not be drafting another vehicle which would lower the air resistance. Also the vehicle must start within a 15 meter length, after which they can have no further assistance from helpers (volunteers who run alongside the bike as it gets going). Volunteers at the end of the course have to help "catch" the vehicles as they have no third wheel to assist with balance when stopped.
