The invention discloses a power output system of a small-sized bicycle. A power input mechanism of the small-sized bicycle is arranged inside a rear wheel rack, so that a chain wheel, a flywheel and a chain or a belt are all under the protection of the rear wheel rack, all-dimensional protection over the power input mechanism is achieved through the rear wheel rack, and the influences of rainy and snowy weather and sunlight on the power input mechanism are reduced; secondly, the power input mechanism can be protected against mechanical damage from foreign objects through the rear wheel rack, and the service life of the power input mechanism is greatly prolonged. The internal space of a bicycle frame is utilized sufficiently, the occupied space of the power output system is smaller, and accordingly the bicycle is smaller in size.
