Light transport vehicle

The invention provides an adjustable suspension system (49,50) for a light transport vehicle useful for transporting children and cargo. The adjustable suspension system comprises a suspension body for operative connection to the vehicle frame, and a pivot arm (316) pivotally connected to the suspension body. The pivot arm has a first end for connection to the transportation apparatus, and a first suspension connector for connection with a main suspension member. The main suspension member has a pivoting end for pivotal connection to the first suspension connector, and a sliding end for sliding support and engagement within an adjustment track within the suspension body. Movement of the pivot arm with respect to the suspension body requires a different force depending on a relative angle of the main suspension member with respect to the first suspension connector.
