1954 Mercury Sabre Flite.

It looks good, just be careful with those fenders they've been known to rattle loose and get shot into the spokes which can kinda ruin your day.

Before you get too excited, that's a reproduction bike, made in china, late 90's, early 2000.

You can tell by the parts. Reflectors, etc.

It's really not much of a reproduction, either, as mercury was a murray brand (murray actually made great bikes up to the 50's, along with huffy, which used to be huffman) and would of been a straight bar before 1950, and a middleweight cantelever schwinn-type frame in the 50's, but without the oversized tubing like the one you posted.

Value, on a good day is 100-150.

if you like it, go for it. $75's not a bad price.
