We are an engineering company dedicated to increasing the understanding of utilty of human powered transportation.

Currently offering:

A rear suspension unit for the Linear Recumbent bicycle. This Unit adds a plush ride and rigidity to the drive train of the venerable linear.






A suspended recumbent tandem is a boon to every marriage.

Note the ability to use a rack with the unit.


The unit replaces the folding Linear chain stays. The folding capability is lost. A 20 inch wheel must be added as well as the brakes, derailleur and seat stay nipples.




We offer the class notes for "Single Track Vehicle Design" ME-441 at the California Polytechnic State University at San Luis Obispo. These notes are a compendeum of 10 years of bicycle design experiments. As well as the Professors experience as a military pilot and engineering consultant at The Air Force Flight Test Center at Edwards Air Force Base and NASA Flight Simulation at Ames Research Laboratory at Mountain View California.

The notes include the theoretical background for the engineer and information for the designer as the the effect of changing frame geometry on vehicle handling qualities. Numerous photographic examples are included.

Weird bike parade day for the Me 441 bike design class.

These are a few of the folks that have successfully used the handling qualities theories in the "Chronicles of the Lords of the Chainring".


You can own the suspension unit for: 415 $ + 21 $ shipping

The "Chronicles of the Lords of the Chainring" is: 32 $ + 2 $ shipping

A computer program to accompany the "Lords" is available in either qbasic or xl. 10 $.
