Abstract

L'invention porte sur une bicyclette de type à rames, qui comprend un cadre (1), une fourche avant (2), une roue avant (3) montée sur l'avant du cadre par l'intermédiaire de la fourche avant et une roue arrière (4) montée sur l'arrière du cadre. La bicyclette de type à rames comprend également un amortisseur de guidon (6) qui est apte à se rétracter et dont la partie inférieure est montée sur la fourche avant. Un guidon (5) est disposé sur la partie supérieure de l'amortisseur de guidon pour commander la direction d'avance de la bicyclette et entraîner l'amortisseur de guidon en étirement en rétraction. Un dispositif de rappel de force (8) est disposé sur le cadre de manière à permettre un déplacement en va-et-vient. Un câble d'entraînement (9) présente une partie s'enroulant sur le dispositif de rappel de force et dont les deux extrémités sont fixées respectivement sur le guidon et sur le dispositif de rappel de force. Un premier plateau de pédalier (11) est monté sur le dispositif de rappel de force. Un premier volant (13) est disposé sur un côté de la roue arrière pour l'entraîner en rotation. Une première chaîne d'entraînement (12) est reliée au premier plateau de pédalier et au premier volant. Par conséquent, l'utilisateur peut entraîner la bicyclette de type à rames à la manière d'un aviron, de façon à réduire la limitation de la place pour le mouvement d'aviron.
