Abstract: A wheeled vehicle includes wheels. A frame supports the wheels. First and second covers cover the wheels or the frame. The first cover includes first, second and third openings. The openings are preferably slots. The respective openings are arranged to form a triangle. The second cover includes first, second and third projections corresponding to the first, second and third openings of the first cover, respectively. The first, second and third projections are inserted into the associated first, second and third openings to couple the second cover with the first cover.

Abstract: A wheeled vehicle includes a seat. A frame supports at least the seat. The frame includes at least a first horizontal section extending substantially horizontally in front of the seat. At least first, second and third covers overlay the frame. The first horizontal section includes a reference position. The first and second covers abut against each other to form a flush surface and overlap with each other to cover the reference position. The first and second covers are attached together to the first horizontal section at the reference position. The third cover is attached to the first cover or the frame at a second location that is spaced apart from the reference position and is determined with less precision than the reference position.
