<p>A dual-drive hub device is mounted on a rear wheel (10) of a bicycle and has a hub (20), a main shaft (25) mounted through the hub (20), and two rear pedals (28) connected to the main shaft (25). At least one one-way bearing (251) is tightly fitted between the hub (20) and the main shaft (25). A rear transmission wheel (30) of a transmission system of the bicycle is mounted around the hub (20). When two front pedals (34) of the bicycle are pedaled, the hub (20) and the rear wheel (10) rotate accordingly. When the rear pedals (28) are pedaled, the main shaft (25), the hub (20) and the rear wheel (10) rotate accordingly. Thus, a rider and a passenger can pedal the front pedals (34) and the rear pedals (28) simultaneously and enjoy ease of bicycle pooling. Fig. 2</p> |
