Welcome to my web page hosted by the IHPVA. My name is Rickey Horwitz, the former owner of Practical Innovations. Contained at this site are detailed plans on how to design and build a recumbent tricycle. The contents of this site used to reside on my own web page, but I have little time now to support it directly. However, if you have any questions concerning this material, please contact me at email@example.com. To learn more about me and my former company select Who Am I? .
The drawings and specifications offered on this web page are for building an advanced version of the tried and true Thunderbolt Sports Recumbent Trike. The original design dates back to 1994. However, even today the performance of this trike is still impressive. I am confident that you shall find my documents exceed in quality and detail to any plans available free or not.
For a specification of this trike, please checkout my old Thunderbolt brochure.
If you have any questions concerning these plans, please email me at firstname.lastname@example.org
After 6/15/2002, I will no longer update this project. Several years ago I made a promise to make these plans available to the public at no cost. I have succeeded in doing this with no compensation other than the bragging rights to claim I have ‘wrote the book on recumbent tricycles’. Please enjoy.
