Hey Rat Rod-
Just a CL find. Did some research on Jamis, The Earth Cruiser, and Boss Cruiser. Thier successes were primarily due to good market place time entry - catching the '78-'82 cruiser craze. It's got some cool specs. Other than that - completely stock. Serial numbers are easy to date on these with an "83" clearly marked.
