Rear steer recumbent bike

April 12, 2019

When I was eighteen I read an article in Popular Mechanics of a rear steer bike. It looked like a good idea for saving weight with the shorter chain. I spent 4 years designing and redesigning this bike. Once it was built it took me 2 hours to get both feet on the pedals. Once…

My first recumbent bike

April 12, 2019

To the best of my memory, this was the first recumbent I built back in 1975. I made it in my metal class when I was 16. I never did get a picture of it, and I never finished it, but it was to be a two position bike either riding upright or reclined.

Burningman trike

April 12, 2019

My first motorized trike was made for my first Burningman experience back in 2000. I used a 3 hp Briggs and Stratton motor with belt drive. This went to a 12″ pulley which drove a 13 tooth sprocket to my rear 6 speed cluster. It could easily carry 3 people, and it topped out at…

Burningman box shelter

April 12, 2019

This was my first use of Coroplast, or better known as fluted plastic or plastic cardboard. This 2-1/2 sheet 4 ft square box used 2×2’s for corner framing. Button head screws fastened the panels to the frame. For transport the shelter was made modular. All I had to do was attach the corner frame to…

MWB recumbent

April 12, 2019

Of all my recumbent bike I made, this was my favorite. I later turned it into a 3 speed with drum brakes up front, then added pontoons for a kinetic race. A young next-door-neighbor boy was dying to have a bike just like mine, so I put this together using his old BMX bike and…

MWB recumbent bike

April 12, 2019

This was my third recumbent build. I wanted to keep the design simple, yet compact. I first ordered a King Cycle recumbent bike seat, but found this too flimsy for my liking. I found this old plastic dining chair and used it for several years. I shouldn’t have cut the sides down, as they turned…

Aluminum SWB recumbent bike

April 12, 2019

This recumbent weighed in at 25 pounds. The main boom was made using 2″ aluminum tubing. To eliminate stress on the aluminum frame I placed the seat mounds directly over the steering tube and rear wheel stays. The crank length was adjustable, but often the hose clamps used to secure the crank tube would fail…

Micro push bike

April 12, 2019

This prototype was my version of a modern micro Hobby Horse. It was intended for short trips to the bus stop, train station or subway. Unfortunately the seat put undue pressure on one’s prostate area. A later version would have included a poly suspension on the rear arm, also having the steering tube and rear…

Attached to the exterior green house is a pole that holds the gravity fed solar shower bag positioned toward the sun. Rain water is harvested for taking showers. To keep…
