An electric one-bag golf cart that carries a single caddie bag for a player on a golf course is provided. The cart body, including a chassis part, a neck part and a steering device part, is formed as an integral hollow piece using the rotational molding method. The wheel system provided under the chassis consists of one front wheel and two rear wheels, with the front wheel being mounted pivotally on a suspension as a free wheel, while the rear wheels are driving wheels using a differential gear device driven by a motor. At the center of the handlebars, which are made of circular rods, a dial-type speed controller is located, and a brake lever is provided under the steering device, together with a lock mechanism.

1. An electric one-bag golf cart in which a cart body, including a chassis part, a neck part rising from said chassis part and a steering device part at the top of said neck part, is formed as an integral hollow piece by a rotational molding method, characterized in that a wheel system provided under said chassis consists of one front wheel and two rear wheels, said front wheel being mounted pivotally on a suspension as a free wheel, while said rear wheels are driving wheels having a differential gear device driven by a motor, that a battery and a control board are mounted in a battery chamber formed on said chassis together with a lid that can be opened and closed freely, and that a speed control dial is provided at a center of said steering device part made of circular rods and a brake lever is provided under said steering device part together with a lock mechanism. 2. The electric one-bag golf cart stated in claim 1 characterized in that handlebars made of circular rods consist of lower grip parts, which, extending on both sides thereof backward, are curved downward and upper grip parts, which are curved upward from corners where said circular rods are bent to a direction perpendicular to an advancing direction of said front wheel and are connected to a core portion of said steering device part where said speed controller is provided.3. The electric one-bag golf cart stated in claim 1 characterized in that said control board comprises a micro-processing unit and determines a voltage level of said battery by digital signals converted therefrom, that said digital signals from said speed controller are also converted into digital signals and are sent to said micro-processing unit, which has a program incorporated therein to determine a revolution rate to control cart speed in response to said digital signals from said speed controller and to unevenness of a surface of a golf course, and which sends said driving signals to said motor driving circuit so as to make said calculated revolution rate approximately agree with an actual revolution rate detected by a revolution sensor for said motor, that said brake lever has a brake switch through which said driving signals to said motor driving circuit are switched over to reverse driving signals or cut off, and that in said lock mechanism is provided a brake lock switch and if said brake lever is fixed, said micro-processing unit outputs a locked status message on said LED display device.
