Abstract: A stroller includes a first wheel assembly, a second wheel assembly, and a handle bar assembly, with each respective assembly being configured to connect to respective first, second, and third rotatable elements of a folding mechanism. Each of the first, second, and third rotatable elements are rotatably supported by a common axle. The stroller further includes a leverage element rotatably supported by a leverage axle, with the leverage axle being supported by the third rotatable element and being arranged in a parallel relationship with the common axle. The leverage element includes an axle slot for accommodating movement of the common axle. The leverage element also includes a first pin and a second pin, with the first pin being rotatably supported by the first rotatable element in a receptacle arranged at a first distance from the common axle, and the second pin being rotatably supported by the second rotatable element in a second receptacle at a second distance from the common axle.
