<p>A foldable pedaling bicycle is provided. A front wheel (8) which can improve the passing ability of the pedaling bicycle, is a direction wheel and bigger than a rear wheel (66). The rear wheel which can reduce the overall size of the bicycle and is convenient for users to ride, is a driving wheel and smaller than the front wheel. The foldable pedaling bicycle runs by using a chain wheel shaft, a chain wheel disc and a chain to directly drive the rear wheel. The foldable pedaling bicycle is driven by two feet to step the pedals (33) which are arranged at two sides of the bicycle frame and respectively connected with a crank connecting rod on a driving shaft-chain wheel shaft. When the pedals are stepped by two feet, the driving shaft-chain wheel shaft (15) is driven to rotate. Meanwhile, the driving force sequentially drives a second-chain wheel shaft (31) or a third-chain wheel shaft (32) to rotate and finally drives the rear wheel to rotate through a chain on the chain wheel shaft. Therefore, the foldable pedaling bicycle can be driven smoothly and stably.</p> |
