About us



In 2006, with humble beginnings Richard Yelvington entered a niche market within a large, highly competitive industry.  After six years, Richard’s creative ideas, aerospace engineering background, and passion to provide solutions has brought us to today's company, Yelvington Trikes.


In 2011, as a consultant to Jack Lavery, owner of a large manufacturing machine shop, Richard shared his vision for the trike industry.  After Jack’s extensive due diligence examining the trike market, the new Yelvington Trikes was established.


As we move forward in today’s dynamic market place, standing still would actually be falling behind. Yelvington Trikes will consistently endeavor to move forward, continually developing our product offering to a higher, better, or more advanced stage.



Jack Lavery, President


As a successful business executive for over 40 years, Jack has held senior executive positions in the Department of Defense, Lockheed Martin, and more than half a dozen successful small businesses.  Jack has utilized his degrees in mechanical engineering, industrial engineering and operations research to integrate multi-functional disciplines into well functioning  teams and technical businesses to provide military, aerospace, defense, and commercial customers superior high quality products at competitive pricing.

Jack has enjoyed two passions equally throughout his life.  Jack’s entrepreneurial passion is growing small technically-oriented businesses by meeting customer’s needs and desires while also creating new jobs for people.  His second passion is the pursuit of outdoor activities including fresh and salt water fishing, golf, boating, riding dirt bikes, and now riding his new high performance Yelvington Elite Trike!

As Chief Executive Officer of Yelvington Trikes, Jack has combined his passions by integrating aerospace design principles with cutting edge technological manufacturing processes and outdoor recreational activities to produce a competitively priced, highly sought after motorcycle to trike conversion kit which allows riding enthusiasts to continue riding whatever the reason or diverse circumstances.



Richard Yelvington, Inventor

Richard Yelvington comes from a long line of engineers, boat builders, craftsmen, and inventors dating back to 1275.  Born in Atlanta, Georgia, Richard was an associate engineer at 19 years old performing prototype design for Cutler Hammer Control Corporation. Over the past 42 years Richard’s involvement with projects for NASA, DARPA, medical, and aerospace companies has produced over 64 United States Patents. Richard has written projects and papers for Los Alamos National Laboratory and his work includes a published paper on the theory of compressed magnetics while consulting with Argonne National Laboratory.

In 2000, after a two year project with NASA, Richard was introduced to motorcycle accessory and motorcycle trike design.  After two years of exhaustive research including studying and assembling 43 trike conversion kits from different manufacturers, Richard made a full time commitment to motorcycle trike design in 2002.  In the fall of 2011, Richard was asked by Jack Lavery to assist in weapons design projects.  While working with Jack, Richard shared his vision for motorcycle trike design and shortly thereafter Yelvington Trikes was established and is currently manufacturing the patented Yelvington 3.0 motorcycle to trike conversion assembly.

Richard is passionate about trike design with a special focus on helping handicapped riders continue to enjoy the freedom of the open road.  Richard is also an accomplished craftsman having restored antique yachts and Jaguar automobiles as well as an avid sailor with over 10,000 miles of blue water behind him.
