Rob, I second what Kurt is saying about issue reaching the pedal, and suggest that you include the rider in your sketchup drawing to optimize seat placement, pivot clearance, pedal reach... For me, it's weld, try, cut, weld, try...

I have played with sketchup but thanks for the You Tube pointer. I use welding exactly as you use sketchup. Weld, try...weld...try. For me reality is whether, for example, my feet actually reach the pedals :=) But if you are thinking open source production of standardized parts autocad is a great way to go. Expensive to have parts machined for a one off design (unless you are the machinist) but efficient if you are thinking about production.
