PROBLEM TO BE SOLVED: To provide a two-wheeled vehicle with an auxiliary power device for cruise traveling by an appropriate driving force without using an acceleration sensor. SOLUTION: A controller 46 performs cruise traveling for driving a driving motor 24 so that a target vehicle speed MT corresponding to a peak value of a detected pedal force is maintained or gradually reduced, determines a gradient state of a road surface based on a correspondence relationship between a current vehicle speed V and the target vehicle speed MT detected by a vehicle speed sensor 37, and updates the target vehicle speed MT according to the gradient state during the cruise traveling. The target vehicle speed is updated by setting the current vehicle speed V to be a new target vehicle speed MT2, 3 when the current vehicle speed V is decreased to a predetermined value or less relative to a previously-set target vehicle speed MT1 during the cruise traveling. On the other hand, when the current vehicle speed V is increased to the predetermined value or more relative to the previously-set target vehicle speed MT3 during the cruise traveling, a vehicle speed smaller than the current vehicle speed V by a predetermined amount is set as a new target vehicle speed MT4, 5.
