Guide system and bicycle using the same

The present invention relates to a bicycle, and more particularly to a bicycle guiding system.

Bicycle is a common means of transportation in our daily life. It has the characteristics of being light and dexterous and non-polluting. It has a good application prospect in the modern society that advocates environmental protection.

In general, bicycles include a steering system, a drive system, and a braking system. Among them, the guiding system includes components such as a frame, a handlebar, a front fork, a front axle and a front wheel. The rider can change the direction of travel and maintain the balance of the car by manipulating the handlebars. The existing handlebars are mainly divided into curved handles and rest handles. Among them, the aero handlebars include an inner handle and an outer handle, and the bicycle with the rest handle can obtain better aerodynamic performance (small wind resistance) when the rider's elbow rests on the inner handle, and is more capable. Combining comfort and riding efficiency, bicycles with more curved handles are more popular with consumers.

However, when the bicycle with the rest rest is on the inner handle of the rider's elbow, the steering will be sluggish and it is difficult to cope with the sudden situation. It is necessary to move the elbow to the outer handle to control the steering more easily, but This will cause the wind resistance to become larger and the riding efficiency to decrease.

The invention provides a guiding system for a bicycle with high riding efficiency and flexible steering.

In addition, the present invention also provides a bicycle using the above guiding system.

In order to achieve the above advantages, the present invention provides a guiding system including a front fork, a front wheel, a frame, first to second handles, and first to second transmission portions. The frame includes a support portion and first and second elbow portions respectively located at opposite ends of the support portion. Each of the handles includes a grip portion and a connecting portion, and the connecting portion is connected to the grip portion through the corresponding elbow portion, and each of the transmission portions is connected with the corresponding handle and the front fork for being used according to the corresponding grip portion The swing direction controls the direction of rotation of the front fork to control the direction of movement of the front wheel.
