The Bamboo Travois is designed to be a simple open-source** blueprint. So simple that villagers all over the world can build it by just looking at a photo of it. The dimensions of the travois, the types of wheels used, etc., all can be determined by the builder, given the type of use(s) to which the travois will be put, the resources available in the local area, etc.
**The inventor holds a U.S. patent on the travois on wheels (includes the Bamboo Travois). Outside of the United States, anyone is free to use the design. For those interested in selling or distributing the travois on wheels in the U.S., please contact Alexis Lewis (firstname.lastname@example.org).
Here are photos of the Bamboo Travois built by inventor Alexis Lewis:
Two 3-meter lengths of bamboo with a 5 cm diameter
One 1.5-meter length of bamboo with a 5 cm diameter
Rope for lashing.
Rope for the cargo net (preferably rope that does not stretch too much).
1.5-meter length of bamboo cut so there is about
16-18 cm between end of the pole and first diaphragm
Two 15 cm lengths of 1.9 cm diameter steel rod, with
a hole drilled in it to hold a cotter pin
Two cotter pins
Two washers with a 2 cm diameter and a

Two 50 cm non-pneumatic wheels with 1.9 cm precision bearings (by Marathon Industries in the United States) [NOTE: The Bamboo Travois also could be built using bicycle wheels.]
