Abstract

La présente invention concerne une bicyclette pouvant produire une énergie auxiliaire au moyen du mouvement alternatif vertical d'une poignée. La bicyclette comprend : une structure permettant de conférer aux pédales une énergie auxiliaire produite par le mouvement alternatif de chaque manche de poignée dans des directions verticalement opposées ; une structure permettant de changer la direction de la bicyclette sans commander un dispositif d'énergie auxiliaire ; et une structure empêchant la vibration du haut du corps d'un utilisateur. Ainsi, la puissance d'entraînement est augmentée, un changement de direction peut être facilement réalisé, et le haut et le bas du corps de l'utilisateur peuvent être entraînés respectivement d'une façon équilibrée.
