Italia Veloce (with 12 options) provides a LEGO-like configuration experience, where customers literally build a custom bike piece by piece. In this case, well-chosen presets (not provided on the website) would be as helpful as a preview of the actual product. Choosing a handle without seeing the bike might make sense for seasoned professionals, but not necessarily for everybody else. Besides, because there are many ways to design a pretty bad bike just by putting seemingly matching components together, without proper guidance, the entire interaction might not lead to the desired outcome: The final product just won’t be as functional or appealing as it should be. A blank start wouldn’t work here. (http://www.italiaveloce.it/index.php)
