Dave Horsfield made several changes to his Ground Hugger XR2, the most significant of which is the drag-link steering system.  The handelbars pivot on a vertical axis and are connected to the fork by a push-rod link.  Dave got the idea from the page at:

XR2 by Stuart Briber

This photo of the Ground Hugger XR2 came to us from Stuart Briber, who is just finishing up with final details.  Stuart used an internal 3-speed hub to simplify the gearing setup.  He reports:  It's great to ride....

This photo of the Ground Hugger XR2 came to us from John Renzelman. This design is unique. He used a universal joint that is designed to be used in steering systems of stock cars, street rods, etc. Click on the following link for information and pictures... U-Joint.

Patterson's Ground Hugger

Robert Paterson first saw Ground Hugger in the original article in Popular Mechanics magazine.  But he didn't purchase plans until they were republished here in 1998.   He started construction in January 1999, and went for his first ride in April.   Click on the image in the left margin to see a full-size version of the photo.    Click on the following links for additional photos....  Close-up of universal jointFrame parts before they were assembledThe frame after it was assembled.

Kyle McCarraher built this superb example of HydroRunner.  There are lots of custom features, including a steering system of his own design, which is less expensive to build than the original one. Click on the photo in the left margin to get a large collage of Kyle's creation.

Brian Bailey's Tri-Magnum

Brian Bailey built his Tri-Magnum on a Kawasaki Voyager 1200.  He included lots of custom features, including positive cabin ventilation, powered headlights and hatch, and a sunroof.  Notice the mini-spoiler built into the engine room hatch.  

Kirk's Tri-Magnum

Kirk and Pam Nickman own the gorgeous Tri-Magnum to the left.  Kirk used a Kawasaki KZ 1000 motorcycle as a basis.  He installed a safety plate windshield so wipers could be installed.  This type of windshield comes as a flat plate that can be cut to fit the opening.  He wrote that "Rain-X works fine, but wipers are better."

Ray Girard built this Tri-Magnum on a Honda Shadow 1100cc V-Twin.  It took a trophy in a car show in Gainesville Florida for "Most Unusual," which Ray comments: Not sure if that is good or bad.   Ray reports 42.2 mpg, and that it handles like a dream on the open road.  You can reach Ray by email at

Builder Mike Grasso is a resident of Noble Park, Australia.  Mike made a number of changes in order to comply with local motor vehicle code, and to customize it for his personal taste.  He writes: When I started, my intention was to follow your plans exactly, but one thing led to another and it took on a life of its own!   Go Mike!

The Tri-Magnum to the left was built by Greg Donaldson of Piedmont, Alabama.   Greg's innovative design changes are hard to see in the thumbnail.   But clicking on the image will bring up a larger, three-gang photo that shows much more.   Be sure to check out the custom wheel covers. 

This Tri-Magnum, built by James Standiford of San Leandro, California, brings lots of attention - even from friendly policemen who stop him just to find out about it. Click on the image for a larger image and more information about this excellent rendition of Tri-Magnum.

Here's another outstanding Tri-Magnum. This one, built by Dan Hoffine of Lafayette, Indiana, is based on a Honda Gold Wing motorcycle. The Gold Wing is actually a better choice than the Kawasaki KZ900 used for the original vehicle. One year, Dan and his wife drove Tri-Magnum to the Daytona 500 motorcycle races and ended up doing a 10-minute interview about his Tri-Magnum experience in a piece that ran on national television.


This Tri-Magnum, which was built by Louis Hausmann, is presently in the hands of John Probst of Louisville Kentucky.   It is now powered by a stock 1977 KZ1000 motorcycle.  But plans are underway to rebuild the engine to drag-bike specs.   Notice the custom roof treatment, which turns the vehicle into a convertible.   

Tri-Magnum by Art Dodge

Art Dodge built this Tri-Magnum over a period of three years.  He did all the work himself, except for the upholstery.  He attached special fixtures to the frame so it can be towed behind his motor home.  Art says he would like to meet others with similar three-wheel vehicles.  You can reach him by email at:

Paul Latulippe"s Tri-Magnum

Paul Latulippe built this Tri-Magnum as his first foam and fiberglass project.  Paul is a member of the Yahoo Yahoo Tri-Magnum discussion group where he has given and received lots of tips.  According to Paul, Lemon Pledge will remove fine scratches from acrylic windows. 

Paul Latulippe"s Tri-Magnum

This Tri-Magnum, built by Robert Wilkinson, is different from the original design of the Tri-Magnum. He has made the proper changes to add on an air conditioner and regular doors. To read more and see more pictures, click on the following link: Robert Wilkinson's T-Mag

Gluhareff Jet

This photo came to us from Erik Hunter with a message that read:  I think the attached photo says it all....  Okay Erik, so you bolted a Gluhareff G8-2-20 jet engine to your mountain bike.  But doesn't everyone who's really cool have a jet-powered bicycle? 

This Phoenix van was built by Tom Cyr. Tom says: It's not a van that's parked in the garage 350 days a year. It gets out! And wherever I go in the Phoenix II, it's not just a trip - it's a parade. I've taken long distance vacations with the Phoenix II to the beach in Galveston, Texas; the Indianapolis 500; Hollywood, California; Lake City, Colorado; Orlando, Florida. Wherever the Phoenix II is, heads turn and crowds gather.

This restyled Tri-Magnum is a work in progress by Eric Whiting. The rendering was done in PhotoShop. Eric is interested in feedback on his design. You can contact him via email at  Eric recently sent updated renderings made in AutoCAD.

This photo of Pegasus was forwarded to us from Popular Mechanics magazine without the original envelope.  (Pegasus was first introduced as a Popular Mechanics project.) And no one here could make out the name on the handwritten note inside.  So will the mystery Pegasus builder, please step forward.

David Henry

The photo to the left shows a work in progress by David Henry.  David is making lots of modifications that may be of interest to others.  The side-panels are removable and the lift duct is being moved to the front to balance the thrust engine he's installing at the rear.  David has promised to send more photos and information on the results. 

Keith Outwater built this MiniFlyer hovercraft from free plans available on this website.  His kids are now enjoying the most unusual ride in the neighborhood.  He used a plastic shower curtain for the skirt, and made a number of improvements.  Although MiniFlyer is designed for kids, Keith says it will actually lift him too.
