The present invention is in the reverse three-wheel bicycle in which a pair of front and rear wheels are coupled

It relates to an inverted three-wheeled bicycle that has three driving units each having a crankshaft by changing the paradigm of a conventional bicycle, and realizes a tilting function by a natural angle at the same time as the front pair of front wheels inclined toward the rear wheels at a certain angle.

Conventional bicycles perform direction change by manipulating the handlebars on the front vertical frame with two hands, and the drive is made of one driving device made only by the force of the lower body to step on the pedal.

In addition, there is a difficulty in providing a separate heavy tilting device in order to solve the decisive weakness of lifting one wheel on the front wheel when changing direction.

In addition, bicycles are being attempted in several structures such as recumbent, several reverse tricycles and hand-footed bicycles other than the general two-wheeled bicycle, but they do not have mobility and convenience compared to two-wheeled bicycles, and they do not have a good marketability because they do not make any special merits.

In addition, the role of modern bicycles is not limited to simply means of transportation, and the functions of exercise and leisure are more important virtues. However, conventional bicycles consist of one limited drive unit that uses only a part of the lower body, so the effect of exercise is limited. It has to be.

Accordingly, in the present invention, a tilting device for the stability of an existing reverse tricycle is implemented more simply and a new driving unit is added to greatly increase the driving force.

In addition, by expanding the limited driving part, it is trying to come up with a wider range of exercise parts.

In addition, by converting the compression power of the body parts (prostate, wrist) supported by the bicycle into driving power, the driving force is improved and the side effect of compression is minimized.

Therefore, by changing the paradigm of the conventional bicycle, the function of the handle part in front of the frame and the saddle part that supports the body in the rear was eliminated, and by creating three driving parts, it produced 3.5 times -4 times (estimated) driving force and created an inclination to the front wheel. A new concept reverse tricycle that generates both steering and tilting; Preferably, the power of the whole body is utilized as a driving force, thereby providing an inverted three-wheeled bicycle that can achieve the maximum full-body exercise effect.
