There was also a Bay Area builder named something like "Hovey" who built similar bikes in the earlier 1970's. We sold a few Rigis at Bike Gallery ca. 1982. One of them went to a high-mileage owner of several nice bikes. He rode the Rigi on one major ride which involved a descent of Larch Mountain in the Columbia Gorge, and had a couple of "thought I was gonna die" moments; the 77 degree head angle took some getting used tof!
