Beschreibung
Zusammenfassung:	A lever/gear transmission bicycle, comprising a bicycle frame (1), and a front wheel and a rear wheel (6) mounted on the bicycle frame (1). The rear wheel is driven to rotate by means of a lever mechanism and a gear mechanism. The lever mechanism swings up and down to drive the gear mechanism to rotate. The gear mechanism is connected to the rear wheel, and at this time, the rotating gear mechanism drives the rear wheel (6) to rotate. A reasonable transmission ratio and the position of the fulcrum on the lever allow the lever gear transmission structure to be more labor-saving and have higher riding efficiency. Le présent modèle d'utilité concerne une bicyclette à transmission par engrenage et levier, comprenant un cadre de bicyclette (1), et une roue avant et une roue arrière (6) montées sur le cadre de bicyclette (1). La roue arrière est entraînée en rotation au moyen d'un mécanisme de levier et d'un mécanisme d'engrenage. Le mécanisme de levier oscille vers le haut et vers le bas pour entraîner le mécanism
