A travel speed controller for use in an electrically powered light weight vehicle with a battery-powered motor and a control circuit. If an operator applies some accelerating force or a physical force, to the vehicle body, the control circuit receives a plus signal from a rotation transmission means attached to its wheel, corresponding to the accelerating force, and calculates an acceleration based on operation treatment of variation of time intervals of the pulse signal, memorizes the acceleration, and supplies to the motor a driving electric current corresponding to the memorized acceleration. If a higher acceleration is calculated, the memorized acceleration is renewed and a driving electric current is supplied to the motor, corresponding to the renewed acceleration.
