ABSTRACT:
The invention relates to a light vehicle such as a golf caddie which includes a body and at least two wheels that are respectively connected to the body by first and second axles. The axles can be pivoted in a first position in which they are tilted against the body and in a second position in which they extend away from the body, where the second position is defined as the driving position of the vehicle. At least one spring acts on the body and on the axles, maintaining the driving position of the axles only by the elastic force thereof, without additional transversal supports and bracing.
