At this time, the braking force acting on each of the wheels 40b and 40c acts the same.

Referring to the effect of the multi-seater bicycle according to the present invention as described above are as follows.

In the process of being used for group and family play in a park or an amusement park, two drivers ride in the rear of themselves and two drivers drive while the driver rides on the driver 10 and the driver 10 The driver will drive while steering and braking, and at this time, the driver can enjoy a sense of speed according to the driving force of the driver.

In addition, in the driving state of the bicycle a, steering and braking are achieved by the driver. At this time, the driving units 30 and 30a are integrally coupled in a state in which the driving units 30 and 30a are arranged at the left and right sides without being connected to one shaft. The driving units 30 and 30a are driven at different rotational speeds according to the driving force of the driver.

That is, even if the driver riding on each of the driving units 30 and 30a does not have the same driving force, the driving units 30 and 30a rotate independently so that each driving unit 30 or 30a is independent of the driving force of the driver. ) Is the ideal rotation.

For example, in consideration of the number of revolutions of each of the wheels 40, 40a, 40b, and 40c during the right turn, the left wheel 40b drives 2.6 revolutions in two rotations of the right wheel 40c. Ideally, the two wheels 40b and 40c are not connected to one shaft, so even if the left wheel 40b is driven at zero rotation, the wheels 40b and 40c achieve ideal rotation. .

On the contrary, in the case of the left turn, the wheels 40b and 40c are in a stable rotation state even though the wheels 40b and 40c are rotated as opposed to the right turn.

In addition, as shown in FIG. 3, when the ground passes through an irregular area while the bicycle is running, the shock transmitted from the ground may be applied to the wheels 40 and 40a of the driving unit 10. 60) and 60a are absorbed, and at the same time, the fixed shaft 21 integrally fixed to the wheel steering body 20 is shifted by the displacement δ by the buffering action of the shock absorber 60 and 60a. The lower the impact of the ground to be transmitted to the handle 13 is blocked.

Therefore, even when the driver passes the irregular area while the bicycle (a) is running, the steering wheel (13) is made to achieve a stable driving state of the bicycle (a).
