After about ten minutes of reading, I launched the installation of the bike rack on my big C4 Picasso. - First assembly: 15 minutes - Second assembly: 5 minutes, - Installations following: 1 to 2 minutes.
You'll understand once hand made, it is very easy to assemble. And once installed, the bikes are very stable.
Note though that the lower strap is likely to hide the license plate ... the "concealment" of the plate being fined!
