Greetings, @franck_R , and welcome to the V1 community forums!
I’m not in France, but am responding in part to generate some traffic so that the topic has activity- which pulls in more members’ participation.
We do have folks in our community who have built LowRiders in France.
One who comes immediately to mind is @Fabien , who I’m tagging here and I’m linking a thread about that activity.
Good luck with your build, and I’m looking forward to seeing your progress and learning more about what you plan to do with your machine.
