A trolley includes a pair of vertical bars defining a pair of legs at lower ends thereof, a supporting plate attached to the lower ends of the vertical bars for carrying articles, such as a golf bag, a sleeve securely mounted to an upper portion of the vertical bars, a lever pivotally mounted to the sleeve, a bracket member mounted on the vertical bars, a pair of arms extending outward from the bracket member and away from the supporting plate and each has a first end pivotally connected to the bracket member and a second end pivotally connected to a connecting member, a linking bar with first end thereof pivotally connected to the lever and a second end thereof pivotally connected to the connecting member, and a wheel removably attached to each connecting member. When pulling down the lever from a lifted position to a lowered position, the wheels move inward and downward onto the ground for supporting the trolley and the article there-on.
