A bicycle with an oval small crankset driving system comprises the oval small crankset driving system, and the oval small crankset driving system comprises a flywheel, a main chain, a left pedal, a left crank, a main crankset, an auxiliary crankset, a main shaft, an auxiliary chain, an oval small crankset, a middle shaft, a right crank and a right pedal. Compared with a common bicycle, the bicycle saves labor during riding, is easy to tread, can quickly pass through a difficult-to-tread area after being easily treaded in a highest point or lowest point interval where force is difficult to apply, further improves the treading frequency, further improves the bicycle speed, and is convenient to use. And meanwhile, the defects that the chain shakes and is easy to fall off, and the bicycle is treaded easily and seriously due to the fact that the bicycle purely adopts an elliptical crankset are thoroughly overcome.
