I have been wanting to build a recumbent for a few months now and I came across this design:

That's it!! Game over. I'm in love! I want one. I have a welder/fabricator who has the skills to build it for me and he's just about ready to go. I have an old schwinn mountain bike for parts, mainly the crankset and derailures, maybe the rear hangers.

The builder, who is not in the same state even, wants me to spec it out so he knows how to build it. I basically need to come up with the frame dimensions. No problem! Right....

So, here I am. Where do I start? I have a 20" kids bike to use for parts, too, mainly the front fork and headset. I imagine that most of the rest will be fabricated, as he builds custom 4x4's and other automotive masterpieces from scratch. www.wickedfabrication.com is his site.

Any advice you all can give would be most appreciated!

Oh yeah, what about a seat? Would a car seat be too much?? I could find a light one
