Problems solved by technology

[0002] At present, the popular bicycles on the market generally adopt the rear drive mode. This kind of bicycle generally increases the power performance through the speed change mechanism. People have made various improvements to this traditional bicycle structure, and there are more and more bicycle mechanisms. To meet the needs and uses of different ages, different consumers and different functions, if some transmission mechanisms are changed to other rear drive methods, such as worm drive or crank drive, and some use front drive methods, but these improvements basically still use Only using pedal...

Abstract

The invention discloses a front-driving bicycle consisting of a frame, a front wheel and a rear wheel. A fixed support frame is arranged between the frame and the driving wheel which is arranged on the front wheel. The driving wheel is fixed on the front end of the fixed support frame via a rotation shaft. A rotation connecting device is arranged between the front wheel and a rotation flywheel which is arranged at the outside of the front wheel. A transmission chain connects the driving wheel and the rotation flywheel. A rocker which is arranged on the frame is articulated with the frame. A crankshaft connecting rod is arranged between the driving wheel and the rocker which has a handlebar on the upper end and a pedal on the lower end. The traditional manner of pedaling is changed by arranging the driving wheel on the front wheel, shortening the distance between the front wheel and the rear wheel. Since the rocker is provided with a handlebar at the upper end and a pedal at the lower end, the bicycle can be driven by hands or feet, or both, making the bicycle more convenient to use.
