I thought about it myself and the following idea.
Pic 1 :
To picture 1: Is it possible to display the bike in 3D? The red line as an example of the background.
Pic 2&3 :

To picture 2 & 3:The red line again as a background and the purple / yellow line as it were cut out, almost without a background.
That the tires stand out from the signature.
I hope I could help a little ^^
