Rotation drives the right slider 1'to move upwards, so that the right pedal also moves upwards. The intermediate flywheel 23 between the left slider 1 and the right slider 1'rotates counterclockwise, driving the transmission shaft to rotate counterclockwise, and the The vertically distributed bevel gears also rotate counterclockwise, which drives the horizontally distributed bevel gears on the axle of the rear wheel 14 to also rotate counterclockwise, thereby driving the rear wheels 14 to rotate counterclockwise, that is, the rear wheels 14 are forwarded and the rear wheels 14 are forwarded The movement drives the entire car body to move forward.

[0049] When the right foot is stepped on the pedal forcefully, the right slider 1'moves downwards, and the flywheel 23 between the left slider 1 and the right slider 1'rotates clockwise, driving the left slider 1 to move upward, thus the left pedal 2 also moves upward. The intermediate flywheel 23 between the left slider 1 and the right slider 1'rotates counterclockwise. At this time, the flywheel shaft of the intermediate flywheel 23 does not rotate with the rotation of the flywheel, so the transmission shaft is also fixed. That is, the rear wheel does not rotate and the bicycle does not move. That is, when the right foot is exerting force, no work is done on the bicycle.
