This book is an amazing idea book! The Energy Cycle, as pictured in Figure 3-16 actually became a viable product called the VitaGoat. No, there are no measurements to quickly make one of your own. You will have to figure this out on your own through some trial and error, kinda based on the one made from a bicycle frame. HOWEVER, this book does present a lot of photos and ideas for making and using various mechanical & pedal-powered devices. If you aren't afraid of welding, you could quickly make the basic frame (figure 3-17) out of 1-3/4" square tubing, add a plastic lawn-chair seat that slides forward and back to adjust for leg length to pedals, use the bottom bracket with crank (gears) and pedals from a cheap mountain bike (get a used one), The height of the section below the bottom bracket is based on keeping the pedal at the bottom of it's orbit high enough off the floor that you aren't hitting your foot on the ground, and the rest of the parts are kinda laid out for you. On page 109 I saw my first photo of a SWB recumbent bicycle. This was totally amazing back in 1977. I have since built at least 10 different recumbent bicycles, both Long-Wheel-Base and Short-Wheel-Base. This is one of the few books that I've permanently kept in my library ever since. Not too long ago, I bought another used copy through Amazon ... just in case. :-)
