With our bikes we are living mainly in the 70th to the 90th of the last century. Most of them have steel frames and shifters at the sub tube. We love the classic way of cycling, hightech isn't ours. However, the car could have a modern look, it's not an oldtimer. But not too bombastic. Main color should stay red, especially in the middle of the car. That part is used as a photo background for our bikes, and red is the best color for that job (see picture 7).
Other colors beside red: white and blue. That are the national colors of The Netherlands, which is name giver of Superfiets (Superbicycle).
Other color option: red, yellow, blue. With some white. That are the colors of the Batavus "Professional", the top model of this honorable dutch brand. Pictures are attached.
If you want to try something else: Please. I won't stop you!

The design should contain our internet adress and our topic: "Klassische Rennräder" (classic road bikes).
PS: The illustrated cyclist attached can be used, too.
PPS: After seeing the first designs I have to thank for the great participation! To bring it in the right direction, please remind the point of using the car as photo background. Red is my color. I bought this car to have a red photo background. Please don't change the color in the lower middle part. With the rest you are free. On picture 7 you can see standing a bike in the "photo position" (next to me). And I prefer to have the logo in white (or ONE other color). Red, white, blue and black is the old version I don't use anymore.
