Abstract

La présente invention concerne un tandem comprenant: une roue avant et une roue arrière; un guidon principal pour diriger la roue avant; un cadre séparant la roue avant de la roue arrière; un ensemble selles fait de deux selles dont chacune comporte, d'une part un support des hanches conçu pour supporter les hanches du cycliste, d'autre part un relief réalisé sur le support des hanches et disposé entre les jambes du pilote, le support des hanches de chaque selle étant orientés en opposition l'un par rapport à l'autre et étant supporté indépendamment l'un de l'autre par la partie supérieure du cadre; un arbre de rotation principal conçu pour tourner sur le cadre; une paire de pédales principales qui sont reliées, avec un intervalle, à l'arbre de rotation principal de façon à faire tourner l'arbre de rotation principal; un arbre de roue arrière conçu pour tourner sur le cadre et sur lequel est montée la roue arrière; et une pièce principale de transmission de force qui relie l'arbre de rotation principal à l'arbre de roue arrière et qui transmet à l'arbre de roue arrière la force produite au niveau de l'arbre de rotation principal. L'invention permet ainsi à deux cyclistes, non seulement de s'asseoir en se tournant le dos et de bouger en toute sécurité tout en ayant conscience de la situation à l'avant et à l'arrière, mais aussi de prendre plaisir à rouler à vélo.
