Hi, I am in UK and building a recumbent trike. Been thinking of building one for about 3 years and finally doing it. I already built one frame with the steetring geometry done right, and rear suspension but the frame was too weak. I had 40mm x 30mm miod steel box section which was 1.2mm thick. I have now bought 40mm x 40mm x 3mm x 5ft long mild steel box section. Much stronger, but the box section is 5kgs (approx 10 pounds in weight. I have bought 2 of them. One for the main frame and some of the other length for the front cross piece. Can someone please tell me what the weight of an average recumbent trike frame would be. Is the box section I have too much overkill for the strength ?
Thanks in advance
