The invention provides a motor-driven bicycle, including a drive motor for generating a self-running power in response to an operated amount of a self-running operation by a driver, capable of achieving a self-running function matched to a walking speed and obtaining an optimum acceleration irrespective of a road condition or a variation in load such as a deadweight. ÄSolving MeansÜ A motor-driven bicycle, which includes a drive motor for generating a self-running power in response to an operated amount of a self-running operation by a driver, is provided with an acceleration detecting portion 203 for detecting an acceleration, and a rapid acceleration suppressing control portion 205 for controlling the self-running power on the basis of the detected acceleration. If the detected acceleration is more than a specific reference acceleration, the rapid acceleration suppressing control portion 205 gradually reduces the self-running power to be supplied to a drive motor M from a reference value determined in response to the amount of the self-running operation, and thereafter, if the acceleration is less than the reference acceleration, the control portion 205 gradually increases the self-running power to be supplied to the drive motor M up to the reference value determined in response to the amount of the self-running operation. <IMAGE> |
