Scooterists, when acting manic
Reach for tools in utter panic.
Blood and sweat flow from fanatic
End result? "Commutamatic".
-"Puddin' Tame," July 1998
And Dave Norton reminds us of &quotWestheimer's Discovery:"... &quotA few weeks spent in the lab can frequently save a few hours at the library."

Commutamatic is an example of a tilting trike. Tilting trikes, like so many microcars or minicars, are odd and rare. But besides that, they tend to have these characteristics:

The most famous tilter it seems is GM's Lean Machine. That, and Jephcott's Micro and Tilt Trike were inspirational. Away we go.

The logs.

The principles.

The design.

I mentioned Professor Jephcott above. Tony Foale, whom I thank here (thanks, Tony!) and below, got to drive Jephcott's "Micro." Here is a picture of the Jephcott Micro showing the design, including the tilt. Note that the rear wheels and the drive unit stay comfortably on the ground while the cabin and the front wheel tip just like a motorcycle. Mr. Foale took the photo, and Dr. Jephcott is at the controls.

The steps.

Of course, I had to build my electric snow blower before I could do this. The funny thing is, I started getting parts for this project about 4 years ago. Bob Batson at Electric Vehicles of America helped me locate a used DC motor and a charger a while back, and last year he sold me the Curtis PWM controller. Sometimes a good project takes time to get rolling. Photos, a description of the steps, and running total time may be seen on the Development Log page.

Thanks to these fine people:
