The four-wheeler is a recreational off-road vehicle similar to a motorcycle in size and functionality. Three-wheelers became popular among the consumer market in the 1960s and 1970s, but its design proved to be dangerous among average riders. The four-wheel design was introduced in the early 1980s, and this improved setup remains used in modern recreational vehicles.
Browse through a collection of four-wheelers and choose one that will best assist with your drawing. To ensure your drawing is proportional with the dimensions of a real four-wheeler, use the rule to create a grid on the picture to divide each detailed section into focused squares for reproduction.
Sketch out the basic body of the four-wheeler, as pictured in the chosen photograph. Keep the pencil marks of the body light during this rough draft of the drawing. Sketch out the wheels as they are positioned in the picture. You should have a basic shape of the four-wheeler at this point.
Add detail to each gridded section of the four-wheeler you are drawing, using light pencil marks through this section as well. Study the picture of the four-wheeler and ensure that the details in your drawing portray the vehicle in a realistic manner. Once you have sketched out the appropriate details and are confident in the general shape, use darker pencil lines to more clearly define these sections.
Outline the four-wheeler and detailed areas with an ink pen to make your drawing stand out from the page. Let the ink dry for a few minutes, then erase all of the erratic pencil lines that you used to roughly shape the four-wheeler in the beginning stages.
Determine a single light source point on the picture to add shading and realism to the drawing of the four-wheeler. It is likely that there is a single light source on the picture you are using as a reference, so you may use the shading in the photograph to guide you through this method in the drawing.
Use a pencil or pen to create shading on the four-wheeler. With pens, use interlacing lines to create a shadow-like effect in the darker areas. This process becomes more familiar the more you use it. Pencil shading is more forgiving, as the lead can transfer to the paper in dark or light strokes.
Clean up any areas of the drawing that may appear rough. Erase any remaining pencil marks that are unnecessary to the final product at this time.
