Hello! New member here from Italy, I've been thinking about building a cruiser/bobber style bike from scratch since I like the style. I don't have any experience with frame building but I do know how to weld/fabricate. I was planning on using 40mm ERW tubing with a wall thickness of 1.5 mm for the main triangle, since I have some already and it is readily available to me if I need more, Do you think this would be a suitable material?
