A bicycle comprising a vehicle frame having a front wheel, a rear wheel, a pedal crank shaft connected, for manual drive, to the rear wheel, and an internal combustion engine connected, for a mechanical power drive, to the rear wheel. A gear train is interposed between the pedal crank shaft and the rear wheel and comrises an input gear, an output gear and an intermediate gear, the latter being rotatably mounted on a rotatable supporting shaft and interposed between the pedal crank shaft and a driving sprocket connected to the rear wheel such that upon transmission of a torque through the gear train, the supporting shaft is turned in proportion to the torque. There is provided on one side of the supporting shaft a rotary shaft which is arranged to be driven with the intermediate gear so as to be turned in correspondence with the rotation speed of the intermediate gear. A swingable lever is connected at one end to the supporting shaft and at its other end to the rotary shaft, the lever being additionally connected at a middle portion to a throttle control member for the engine.
