Hi, in plus of what are already replied, I want to put emphasy on taking the image with the less distortion possible.
Near shots put lot of distortion, which is null at the center and high at the edges, the ideal are shots taken from as far as possible, maybe with a teleobjective
Also the bike should be perfectly perpendicular to the camera sight as possible.

Other than that, as explained in the other posts, it is just a matter of inserting the image and drawing, scaling and measuring over it.
