Problems solved by technology

But the existing front-wheel-driven bicycle also has its disadvantages. The one is that the transmission ratio cannot be enlarged, and a larger front wheel must be used to ensure the speed of the vehicle; When skating, the feet have to passively follow the wheels, which makes people feel extremely uncomfortable; the third is to continue to use the bicycle’s rotating driving method, and it is difficult for the two feet to control the running direction of the front wheels, so a handlebar must be added, which will cause It is extremely inconvenient to get on and off the seat bike

Abstract

The invention relates to a chair bicycle, wherein it uses small wheel, low chair, and handle of three-wheel structure; uses front-wheel reciprocal pedal driving method; uses foot steering method; uses transmitter formed by drawing rod, chain, and flywheel; converts the pedal into rotation of front wheel. The invention has safe driving and low power consumption.

Description

Technical field: [0001] The invention relates to a bicycle, a front-wheel driven bicycle with a seat. Background technique: [0002] People yearn for seat-type bicycles, which are as comfortable as riding a car, but traditional bicycles can only use high and small saddles due to structural defects. In order to realize the seatization of bicycles, the most important thing is to change the pedaling posture of the bicycle, from downward pedaling to forward-stretching pedaling, just like stepping on the accelerator when driving a car. And the front-wheel-driven bicycle is the forward-stretching pedaling posture, so the front-wheel-driven bicycle is an effective form to realize the bicycle seat. [0003] The earliest days of bicycle invention were front-wheel drive, and now some trendy bikes are back to basics and also use front-wheel drive. Adopting the front-wheel drive can also shorten the car body, lower the seat and make the structure more cylindrical. But the existing fr...
