A motorized vehicle has wheels mounted on a vehicle body for undergoing rotation to cause the motorized vehicle to undergo travelling, electric motors for selectively undergoing forward and reverse rotation to rotationally drive respective ones of the wheels, brakes for applying brake forces to respective ones of the wheels, handlebars extending from the vehicle body, and turn control levers mounted on the handlebars to undergo angular movement within a range of preselected angular positions. The turn control levers are connected to respective ones of the brakes and respective ones of the electric motors so that the electric motors undergo rotation simultaneously in opposite directions in accordance with the preselected angular positions of the turn control levers to turn the motorized vehicle while the motorized does not undergo travelling.
