The rider lies on the reclining seat cushion 9 of the 2-wheel drive reclining bicycle, and the hands naturally hang down. The bicycle handlebar 8 is placed on the pedal 12 to drive the front wheel 11 forward.

Figure 8 shows the driving process of the front wheel 11: The rider's thighs force the pedal 12, the pedal 12 drives the front wheel rack 21 inside the front wheel drive 13 to move forward, the front wheel rack 21 drives the ratchet 22 and the front wheel 11 turn forward.

The 2-wheel drive reclining bicycle relies on the arm traction device to drive and turn the rear wheel 2 (ie, the bicycle turns).

Please see Figure 3 and Figure 4:

In Figs. 3 and 4, the arm pulling device is composed of a fixed arm 5, a rotating shaft 6, a crank 7, a handle 8, and a pulling arm 14. The arm traction device converts the force of the rider's arm contracted upward into a force that pulls the rack forward, driving the ratchet and the rear wheel to rotate forward. The specific description is as follows: The fixed arm 5 fixes the rotating shaft 6 of the arm pulling device and the two-wheel driving rear fork 3 together. One end of the crank 7 is a handlebar 8 and the other end projects into the rotating shaft 6, and the crank 7 and the handlebar 8 can be Rotate upward with the shaft 6 as the center. The other end of the portion of the crank 7 that extends into the shaft 6 fixes the trailing arm 14. The angle between the trailing arm 14 and the crank 7 is fixed.
