Briggs and Stratton motorized 6 speed bicycle

March 13, 2022

This was the Hardley Davidson. Hardley, not Harley, get it?  It was one of my favorite Burningman rigs. The engine and transmission design was borrowed from my first Burningman motorized trike which had a 3 hp motor. This has a 2 hp motor with a small pulley driving a BIG 12″ washing machine pulley which…

Lumber hauling bicycle

January 8, 2022

Since making a wood rack for my bike that carried 6 totes of belongings I’ve always thought that carrying lumber or long loads  wouldn’t be that difficult with the right supports. At first I was going to weld these two brackets to the frame, but after some thinking I realized it wouldn’t be that difficult…

The Bike Box

January 3, 2022

The defunct Donkey Boxx company use to make durable fluted plastic bike panniers. Too bad they didn’t make it.  I’ve always thought if you don’t have any brake or shifting cables in the way the mid section of a bike frame would make for a convenient and balanced storage space. The 4.5″ width keeps the leg-rub…

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

Itching to have a test ride. Of all the recumbent bikes I’ve made, this was my favorite and most used. I later added a 3 speed wheel with drum brakes up front, then added pontoons for a kinetic race, which never happened. A minute after this image was taken everything went South. The pontoons flipped…
