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…

Briggs and Stratton powered bicycle

November 15, 2021

I’ve been wanting to have a powered bicycle (with usable pedals) to tow my bicycle campers with. Electric to me is too much money and a hassle, plus on a long journey when the juice runs out you’re stuck pedaling. I favor the old briggs motors. They’re 4 cycle (no need to add oil to…

Economical Reverse trike

March 31, 2021

My dream project conceived over 40 years ago. This is my third attempt at creating a high mileage one person trike. Borrowing ideas from Dale Malewicki’s California Commuter trike I fashioned a basic rigid front swing arm. This helps stabilize the trike in corners but also makes for a bumpy ride. To do it again…

DIY car top carrier

May 9, 2019

Here I am playing around again with a $20 sheet of 4×8 foot 4mm thick fluted plastic. I thought I’d make a car top carrier. I buy my fluted plastic at Laird Plastics Inc. (206-623-4900) in downtown Seattle Washington where they stock several thicknesses, sizes and color choices. Made with zip ties and held down…

Electric recumbent scooter

April 13, 2019

  This is the first stand up scooter I made into a recumbent. It was a hoot to ride for about 4 miles, then the battery would drain and soon you were forced to walk the rig home.

Little burningman trike

April 12, 2019

  The second time I went to Burningman I brought my older brother. I brought the big trike and made this little sail trike adding a 2hp Briggs and Stratton edger motor for back-up power. I pounded on a roughed-up tube onto the drive axle for front wheel food activated friction drive. I made a…

High mileage trike #2

April 12, 2019

This was my second attempt at making my dream 150+ mpg one passenger vehicle. I started out with a rear engine design but opted to try a front engine placement for better cooling and balancing.   Later I tried to make it a rat rod type vehicle, but eventually abandoned the idea all together. Fast…

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…

Recumbent scooter

April 11, 2019

This was the third of my stand-up scooter recumbent conversions. This Zooma was built a bit cheaper than the Goped. The Goped had single forks for easy access to the wheels in case of a flat, and it had a big rear disk brake. The Zoom however had dual drum brakes on both wheels, rear suspension…

Recumbent Goped

April 11, 2019

    This was the second time I turned a stand-up scooter into a recumbent scooter. I cut the Goped in two and welded on an 11″ extension. I shortened the steering column, added rake to the single front fork and added an extended tube for the foot peg ‘T’ bar. A seat post was…
