The ConferenceBike is a 7-seat human powered vehicle created by artist Eric Staller and manufactured by Velo.Saliko. One person steers and all may pedal . The bike has a circular jointed drive-shaft and rack & pinion steering. In most countries it has the same legal status as a bicycle. There are now 300 ConferenceBikes in 18 countries. They are used primarily for tourism, with a few used on university campuses or for teambuilding.
