location on 12 May 2002 when he reached on a serial production bicycle and , on a prototype bicycle, a world record. Markus Stöckl did beat the serial production bicycle record in 2011 when he reached on a volcano in Nicaragua and again in 2017 when he reached down a volcano in Chile. The prototype bicycle record, on a volcano, still belongs to Barone. Hour records The hour record for bicycles is the record for the longest distance cycled in one hour on a bicycle. The most famous type of record is for upright bicycles meeting the requirements of the Union Cycliste Internationale (UCI). Hour-record attempts are made in a velodrome, frequently at high elevation for the aerodynamic benefit of thinner air. Between 1997 and 2014 the UCI retrospectively restricted hour record competitors to roughly the same equipment as was used by Eddy Merckx in his 1972 record. In 2014, the UCI changed the hour record rules to permit using any upright bike allowed for endurance track events. However, other retrospective changes to hour record regulations are why the current hour records are not the farthest absolute distance. The UCI hour records are: UCI men's record: Filippo Ganna , 2022, UCI women's record: Ellen van Dijk , 2022, UCI farthest distance men's: Chris Boardman , 1996, Another type of record registered by the International Human Powered Vehicle Association (IHPVA) and the World Human Powered Vehicle Association (WHPVA) is for human-powered machines, typically fully streamlined recumbent bicycles. These feature a lower frontal area than a UCI bicycle due to their recumbent seating design of the rider. They enclose the rider and machine in aerodynamic shapes made of carbon fiber, Kevlar, or fiberglass to reduce air resistance. A further type of record is for partially streamlined recumbents, which are open but have either a windshield in front or a streamlined tail-box in the rear. This is registered by the World Recumbent Racing Association (WRRA). Streamlined recumbent bicycle (bicycle and rider enclosed in an aerodynamic shell): Francesco Russo of Switzerland set a new World Record by covering in one hour at the DEKRA test track in Germany on 2 August 2011. This record is approved by the WHPVA. On 19 July 2009, Sam Whittingham at the Ford Motor Company's 5-mile oval test track in Romeo, Michigan, achieved 90.598 km. This record was approved by the IHPVA and WHPVA committees. In 2008, Damjan Zabovnik
