I tried the Nishiki Tamarack from Dick's Sporting goods, and hated it. Dick's was good enough to take it back. I got it for $217 with tax, I thought I got a great deal. But it turned out to be too uncomfortable, and I did not think I could fix that.
The saddle position has the front up too high, and the only way to adjust it, is to make it worse.
Strangely, "comfort bikes" seem to be the least comfortable.
