Using the principle of automobile differential, by improving the central axis system of the bicycle, the left and right differentials are realized by using one-way bearings, and the two large and small gears and the bridge gear are combined to form A differential system. This allows the pedals to rotate at will and charge the bicycle with force. When it is on a slope, one foot is perpendicular to the horizontal plane, while the other foot is not perpendicular to the horizontal plane and has a certain angle with the axis. Now, lean backwards on the other side. At this time, pressing down can drive the bicycle forward.
The advantages of riding a bicycle at will are fast starting, strong climbing ability, good cruising ability, and more comfortable and safer riding, which is helpful to all bicycle enthusiasts.
With traditional bicycles, there is no response when pedaling forward or backward. Of course, there is also a kind of dead flying, where pedaling backward is the brake. However, a 56-year-old uncle in Chongqing invented a bicycle called any pedaling. , the reason why this bicycle is called "free pedaling" is because whether it is pedaling forward or backward, the bicycle moves forward, subverting the traditional bicycle riding method.
The uncle has also applied for a patent for this bicycle and opened his own company. The sales of this bicycle are still good.
