Burningman pedal car

May 13, 2019

    When my wife decided to come with me to the Burningman art festival I started looking for ideas on a two person pedal vehicle that I could make for the event. I spied on this picture. During WWII when France was occupied by the Germans and fuel was confiscated for the war effort,…

FWD recumbent trike

May 13, 2019

    I had an idea of making a skate type quadracycle. I felt this would be a fun racing vehicle on a short tight-turn course. Before making a full scale mock-up I wanted to test out the idea of using neoprene wheels. I purchased two wheels from a push scooter outfit and decided to…

The Cycle Kart

May 13, 2019

For PDF plans, click here! Once my other prototype proved the neoprene wheels would work, I ordered 4 wheels from a push scooter outfit. These are 9″ in diameter, which are bigger than most. A BMX free wheel hub was added to the drive wheel. I don’t have proper machining tools for accuracy, but I…

Teardrop bicycle cover

May 8, 2019

  This was an attempt to make a teardrop shell fiberglass plug for my road bike. Plywood ribs were attached together using 90 degree brackets. Holes spaced 4″ apart were drilled on the rib edges. 1/8″ wire was treaded thru the holes. Thin wire was used to attach the chicken wire to the 1/8″ wire…

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.

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…
