81 speed trike in progress

Cool frame design. How you gonna do the rear suspension? bill g

Here is a link to some pictures of my newest trike, in progress. I hope to have it rideable in a
week or two, and actually finished a few weeks after that. The tubing is 3/8" & 1/4" diameter 4130
CrMo. It will have rear suspension, hydraulic front disc brakes, and a mid-drive that allows for a
ridiculous 81 gear combinations. This is a somewhat high riding design to accomadate the position
my neck requires. pictures.care2.com844656287Open ↗ Thanks for looking at my stuff.

The fairing angle is all wrong and that seat...It'll never sell....sheeesh -------just messing with
you---I love it----------- That mid-drive is scarey, the highest I went was 63, 7x3x3 and I have the
same seat, flag mast position, front tires. Love the height of your USS grips though, mine are sooo
low it looks like I am gripping my buttocks. More tadpole details once ur finished....pleeez

Thanks. All is in place except for an air adjustable shock. The mid-drive and swingarm pivot is
shared on a 12mm shaft, thus eliminating drive induced pogo.The shock will go in place of one of
those wood blocks beneath the seat, horizontally. I'll have better pictures later.

I should mention that the completed trike in the photo(me sitting on it with dogs about)is the Tulpa
Trike of Yore. The new trike, dubbed Chaco, will probably be purple. rorschandt

Oh Yeah RU planning on sticking with the VT5000s or will there be any Disc Brakes in the future?

Looks great, Dean! A space-frame recumbent trike. I like it!

How do you like the Swanson seat?

Regards,

Tony

Very Ducati-esqe

Looks great! I wanted to build a space frame similar to that but using a dihedral type of structure.
Unfortunately, aluminum was not a good choice for such a structure. Please post some pictures when
you have it completed.

It seems to me you are out of the homebuilder class and are now at a pro level. The space frame
looks great - wish I had the smarts to design and build something like that.

Oh yeah, I also like the neat garage, the dogs, and the Beemer convertible.

I knew that....eventually. I kept pics of the Tulpa from last year and when I saw it again...at 1st
I thought, damn he has done a clone, even kept the red paint and Drum Brakes...then I thought maybe
you moved the Drums to the clone....then I compared the old pics and the new pics and realized you'd
made an exact clone...then I figured it all out.

Beautiful design. Looks like a sculpture. Is the space frame a stiffer and/or lighter structure than
large-diameter boom tube, or was there another reason?

Definitely post some photos of the finished trike and let us know how it handles.

Theoretically, the spaceframe uses less metal and is much stiffer. If I did it right, the main frame
should behave like a rectangular tube that is 3" by 4" with about a third the weight of a steel tube
that size. Plus it looks cool. (~: Wind resistance may be increased because of "all those little
tubes", but I've some ideas to counteract that.

rorschandt

Counteracting increased wind resistence eh Wonder how much a sheath of Carbon Fiber or Fiberglass
would weigh?...maybe add side sockets to connect Wings.

Saran Wrap would be much cheaper (~: and probably lighter.

rorschandt

Damn...I was going to say Saran Wrap but I thought it would be too simple. How about this one: Make
all the vertical tubes 3 sided with razor sharp edge facing forward to cut through the wind...also
handy for slicing Kosher Salami while sitting there waiting for the Traffic Lights to turn Green.
Just think of all the accolades from female DF cyclists...COOL trike, BIG Salami.

You'd get boundary layer seperation at the trailing corners, and almost certainly more drag than
sticking to round tubes of the same width. Triangles facing the oppositte direction would be better,
but possibly still not as good as circular tubes (even ignoring teh fact that teh circular tubes may
well manage as smaller sections).

You can slice teh salsami whichever way the triangles face.

You might try covering the frame with heat-shrinkable lightweight fabric made for covering model
airplanes. Or even the heavier fabric sold for homebuilt aircraft. Monokote would be even lighter,
but would tear too easily. You might find a translucent color that wouldn't totally hide the
spaceframe.

Beautiful job on the frame. I've always liked spaceframes, like Birdcage Maseratis, 300 SL's,
Ducatis, etc.
