This attention-getting two-seater was engineered to be built from ONE bicycle, some PVC pipe, and a few miscellaneous parts using typical hand tools many people already have. Use this detailed account of my successes and failures to help you design your own bike. You can spend thousands on a four-wheel commercial bike or you can have the fun of building your own. Sure, you can find plans on the Internet, but the ones I found often required two identical bikes and expensive customized parts from a machine shop (and they still cost more than this book). I will show you how I made mine from a single bicycle I picked up at a yard sale for $10. You'll find many design and construction hints and suggestions along with 38 full-color pictures to guide you. If you are even thinking about attempting such a project, this book is for you.
