Here are pictures of a cart that I made out of an old
Coos Bay Flier ( originally designed by Don Harse) style recumbent trike I had built in Cleveland.
This Cart proved itself reliable and useful in a variety of difficult terrains.

I suggest that  this design be adapted to utilize the rear triangles from old bicycle frames and standard bicycle wheels instead of the cantilevered Phil Wood hubs that are used in the existing cart. Although the cantilevered wheel design is simpler,  the wheels will be harder to find and costly if we have to purchase them.
