I just went for a test ride with about 120 pounds. The ride felt very rubber band like at slower speeds. Is this common?
I know what you mean. 120+35lbs is a very large load. I wouldn't be at all surprised if the rubbery feeling is from frame bending and rear tyre deformation. I get lurching with my trailer when fully loaded, and I assume it's just because the transmission of power during cycling is typically uneven, and you have a large passive load behind you, the inertia of which is appreciable. There may a significant lag in the power transmission too, which may give the lurchy feeling.
It's a very nice conversion. You're not in Ann Arbor by any chance?
